Q&A: What is the ‘global stocktake’ and could it accelerate climate action?

As nations gather at the COP28 climate summit in Dubai, top of the agenda will be the culmination of a process known as the “global stocktake”. This core component of the Paris Agreement involves an exhaustive appraisal of how far the world has come in tackling climate change and how far it still has to go. Over the past two years, governments, scientists and civil society groups have submitted thousands of documents into this process and spent hundreds of hours debating their contents. The main technical conclusions emerging from the stocktake are not new. Nations are not cutting emissions fast enough, they are not sufficiently prepared for climate hazards and developed countries are not providing enough support to developing countries, But the stocktake is more than just a review of progress. It is a key part of the Paris Agreement’s “ratchet mechanism”, which encourages countries to scale up their climate ambitions over time so as to avoid dangerous warming. Governments have submitted proposals for how the main, political outcome of the stocktake could accelerate climate action. Ideas include phasing out fossil fuels, tripling renewable energy capacity and raising climate finance to the trillions that developing countries need. At COP28, countries will negotiate which elements make it into the final outcome, which will help determine the pace of change in the coming years. However, one expert tells Carbon Brief that, with so much on the table, the global stocktake risks becoming a “dumping ground” for “politically thorny discussions”, which may hamper its ability to drive meaningful change. What is the global stocktake? The global stocktake (GST) is a five-yearly temperature check that is a vital part of the Paris Agreement, housed under Article 14. Nations that signed on to the agreement in 2015 also agreed to monitor, assess and periodically review collective progress towards meeting the Paris long-term temperature goal and to take stock of their climate actions. The GST is meant to help countries collectively assess where they are, where they want to go and how to get there in terms of climate action and to identify gaps to course correct. It is meant to be an assessment of mitigation and adaptation actions so far, as well as climate finance provided and technology transferred from developed to developing countries, “in the light of equity and the best available science”, per the Paris Agreement. The GST is split into three phases: an information collection phase to gather inputs from all parties and non-parties, a technical assessment phase of these inputs and other evidence, and a “consideration of outputs” phase, for countries to decide what to collectively take away from the process. The final, political phase is scheduled to conclude at COP28, to inform the next round of submissions of countries’ climate pledges in 2024-2025 and to “enhanc[e] international cooperation for international climate action”. Back to top What is the scope of the stocktake? The information feeding into the GST comprised more than 170,000 pages of documents from governments, business and civil society groups, supported by over 252 hours of meetings and discussions. These submissions were categorised into three main areas of climate action, which were decided back in 2018 at COP24 in Katowice, Poland. Nations agreed to evaluate progress on mitigation – cutting emissions – as well as adaptation to climate hazards and “means of implementation and support”. The latter point refers to how much finance has been raised to help developing countries take climate action. It also covers nations sharing low-carbon technologies and increasing their capacities to deal with the challenges ahead. Parties specified numerous “sources of input”, including greenhouse gas inventories, assessments of national climate plans and analysis of adaptation projects. They also agreed that the stocktake “may take into account, as appropriate” two more major topics. These were the unavoidable loss and damage resulting from climate change and “response measures”, which includes the social and economic consequences of climate action, for example on people working in the fossil-fuel industry. In the final synthesis report that emerged from the technical phase of the stocktake, which will inform political decisions taken at COP28, loss and damage was included as part of the section on adaptation. Response measures were filed under mitigation. However, in the draft GST text that has been prepared ahead of COP28, these issues are separated out under their own subheads. Civil society groups have emphasised the importance of ensuring loss and damage, in particular, is prominent in proceedings. How has the stocktake progressed so far? The GST began after COP26 in 2021, with a period of data collection that continued until March 2023. Prior to this, parties had negotiated the rules of the stocktake process and what kind of “inputs” would feed into it. During this period, country reports, scientific studies and other documents were submitted into the stocktake process for consideration. The second phase – the technical assessment – began in June 2022. This consisted of three “dialogues” that took place at the UN intersessional talks in Bonn in 2022 and 2023, and at COP27 in Sharm el-Sheikh. These sessions provided time for evidence to be discussed by country representatives, civil society groups and climate experts. The dialogues proceeded relatively smoothly within the UN talks but, as Carbon Brief has reported, familiar issues emerged within them. Examples include disputes between developed and developing countries over historical responsibility for climate change and civil society groups highlighting the role of fossil-fuel lobbyists in the discussions. The outcomes of each technical dialogue were recorded in summary reports released a few months after the close of each session. These were followed by a 46-page synthesis report prepared by the stocktake’s co-facilitators, with the assistance of the UN Climate Change secretariat. This serves as a “comprehensive overview” of all the inputs and discussions. The evidence laid out in this report will serve as the basis for the political part of the GST at COP28. Nations have already submitted documents to the UN outlining how they interpret the synthesis report’s findings and the stocktake-related outcomes they would like to see emerge from the COP28 summit. How could the global stocktake accelerate climate action? The GST synthesis report concludes that there is a “rapidly narrowing window to raise ambition and implement existing commitments in order to limit warming to 1.5C”. Achieving the 1.5C target, or even the “well below 2C” goal, requires nations to fill the extensive “implementation gaps” between their climate strategies and real-world action. It would also require them to come forward with new strategies that are Paris Agreement-aligned. According to the synthesis report, existing pledges would result in warming of 2.4-2.6C, with the possibility of cutting this to 1.7-2.1C if long-term net-zero targets are fully implemented. As part of the Paris Agreement’s “ratchet mechanism”, the stocktake is explicitly intended to encourage such raising of ambition. There are several ways in which governments and civil society groups are proposing it could achieve this. Much of the focus is on signalling to countries what they should submit in their new, enhanced climate plans, known as nationally determined contributions (NDCs). Nations are obliged to submit NDCs every five years and the next round is due in 2025. The synthesis report notes that “more ambitious mitigation targets in NDCs are needed to reduce emissions more rapidly”. Greater ambition could involve new targets for both 2030 and 2035, and NDCs that cover emissions from entire national economies, not just parts of them. It could also involve NDCs based on absolute emissions reductions rather than cuts in emissions intensity. (Many nations have targets based on reducing emissions per unit of GDP, even as their overall emissions increase.) Article 4.4 of the Paris text says that developed countries should “tak[e] the lead” with “economy-wide absolute emission reduction targets”, whereas developing countries were “encouraged” to move towards “economy-wide emission reduction or limitation targets”. As it stands, many developing countries with high emissions, including China, India and Saudi Arabia, have less comprehensive NDCs, as Tom Evans, a policy advisor on climate diplomacy at E3G, tells Carbon Brief: “There [was] this agreement that developed countries would set economy-wide targets from the get go, and the developing countries would move towards setting them over time… Many of the developed countries – the EU and the US – [say] ‘over time’ is now.” At COP26, nations were “requested” to come forward with more ambitious plans in 2022, but this was largely ignored. The 2025 deadline for new NDCs, on the other hand, is part of the original Paris Agreement and is therefore widely accepted. In their suggestions for the GST outcome, some have made a point of emphasising that new NDCs should be submitted as early as possible – either “well ahead of” or up to a year before COP30, at the end of 2025. Perhaps the most high-profile elements being considered for inclusion in the final stocktake outcome are sector-specific proposals, including targets for phasing out fossil fuels, tripling renewable energy capacity and doubling energy efficiency around the world. (For more on these ideas, and others, see: What are countries and blocs expecting from the stocktake?) Another priority for some is ensuring that, beyond simply committing to global goals, countries use their new NDCs to explain how exactly they would contribute to such targets. Evans tells Carbon Brief that while there is a lot of focus on “flashy” topics such as fossil fuel phaseout, NDCs remain the main mechanism for making the Paris Agreement work. “The NDCs are what you can actually hold everyone accountable to. It’s the agreed terrain,” he says. Alongside measures to cut emissions, developing nations in particular would like to see the GST usher in greater ambition around climate adaptation. The synthesis report concludes that progress on both adaptation and loss and damage “must undergo a step change in fulfilling the ambition set out in the Paris Agreement”. Negotiations over a “global goal on adaptation” (GGA) will still be on-going at COP28. As a result, this component in the international effort to make countries more resilient to climate change will not feed into the stocktake. However, Sandeep Chamling Rai, a global advisor on adaptation policy at WWF, tells Carbon Brief that the stocktake could still work to inform and reinforce the GGA: “For this first round of the GST, parties might create a concrete link with the GGA and might have more concrete links established for the second global stocktake cycle.” A key element of adaptation and mitigation efforts for many developing countries will be assurances that adequate climate finance is provided after the first stocktake. Groups such as the Like-Minded Developing Countries (LMDCs) have made it clear that, from their perspective, any scaling up of mitigation ambition needs to go hand-in-hand with scaling up climate finance. Avantika Goswami, a climate policy researcher at the Centre for Science and Environment in India, tells Carbon Brief: “Without dedicated efforts to ramp up finance, you’re not going to achieve the triple [renewable] energy target, so that’s definitely something that needs to be reckoned with in the global stocktake outcome.” The synthesis report concludes that “accelerated action is required to scale up climate finance from a wide variety of sources, instruments and channels, noting the significant role of public funds”. More broadly, the report also says it is “essential to unlock and redeploy trillions of dollars to meet global investment needs” and make global financial flows consistent with Paris Agreement goals. Countries must finalise a “new collective quantified goal” (NCQG) for developing country climate finance in 2024. Developing countries want to see a goal that is more ambitious and based on an assessment of their needs – rather than picked arbitrarily, as with the previous “$100bn by 2020” target. Many have stated they want to see the analysis from the stocktake inform this new goal. Alongside finance, developing countries have also pushed for the GST outcome to include language that encourages developed countries to share their climate technologies and provide more support for capacity building in developing countries. Back to top What are countries and blocs expecting from the stocktake? From “keeping 1.5C alive” and fossil fuel phase-down language, to addressing unkept climate finance promises, countries’ expectations from the GST are varied. Submissions made this year against the backdrop of increasing climate impacts reveal growing divergence between developed and developing countries. “Without dedicated efforts to ramp up finance, you’re not going to achieve the triple [renewable] energy target, so that’s definitely something that needs to be reckoned with in the global stocktake outcome.” The synthesis report concludes that “accelerated action is required to scale up climate finance from a wide variety of sources, instruments and channels, noting the significant role of public funds”. More broadly, the report also says it is “essential to unlock and redeploy trillions of dollars to meet global investment needs” and make global financial flows consistent with Paris Agreement goals.

Kolkata’s noise, air pollution levels soar on Diwali

Kolkata was once known as a model for controlling noise pollution. This year, the city of joy had a blast, literally, on Diwali night on November 12, 2023, violating Supreme Court of India’s orders on bursting polluting firecrackers. Data, accessed from the Central Pollution Control Board and West Bengal Pollution Control Board (PCB), confirmed that the blasting started to shoot up after 10 pm and reached a crescendo around midnight. It continued till wee hours of November 13, triggering high noise and air pollution. It took about 10 hours for the air pollution to come back to pre-cracker bursting period level, the data showed. Environmentalists alleged the administration did not take action despite the violations. The Supreme Court in 2018 had allowed the use of only green crackers from 8 pm to 10 pm on Diwali night. However, these directions were violated with impunity this year. State PCB officials accepted there were large-scale firework violations on Diwali night, with blasting increasing after the Supreme Court declared the 10 pm deadline. However, they tried to shift the onus on police for action and on people for awareness. Pollution peaked at midnight Both the air and noise pollution peaked close to midnight and only started to settle down around 3 am, showed the official data. The concentrations of PM 2.5, the most toxic ultrafine particulate mattter, had shot up dramatically from evening to midnight. Overall, PM 2.5 took nearly 10 hours to return to the level of the pre-cracker bursting period, showed data generated under the National Clean Air Plan (NCAP) set up by the Union Ministry of Environment, Forest and Climate Change. The data, analysed by think tank Climate Trends, showed an average of PM 2.5 was 82.8 μg/m3 at 8 pm on Diwali night in the city. The levels started to peak from 9 pm — 152.3 μg/m3 — surged to 358 μg/m3 at around 2 am on Monday and then dipped to 79 μg/m3 at 6 am. The national limit for PM 2.5 is 60 μg/m3. Abhijeet Chatterjee, an air pollution expert from Bose Institute and NCAP advisor, pointed out the situation could have been far worse, if the meteorological conditions this Diwali were not favourable. “Firstly, the wind speed was at least 1 metre per second faster than earlier November Diwali evenings, which facilitated the quicker dispersion of the pollutant. Moreover, the planetary boundary layer was also on average 150 metres higher compared to the earlier November Diwali nights, which further facilitated the quicker vertical dispersion of the pollutants,” explained Chatterjee. Pollutants remain confined in the planetary boundary layer and come closer to the surface during the winter, maximising the impact of pollution on humans. “This sudden surge, around four times, has a significant bearing on people, both those already affected and others, increasing heightened ailments, hospitalisations and long-term health problems,” opined Anumita Roy Chowdhury, executive director for clean air and sustainable mobility at the Delhi-based think tank Centre for Science and Environment. Most of the stations also recorded very high noise pollution levels at midnight — much higher compared to national limits. For several stations, the noise levels were higher or similar to those around 10 pm. Bagbazar, in north Calcutta, recorded 88.9 decibels at about 12.30 am, while the level was 76 decibels at about 10 pm. Similarly, Patuli, a residential area off E M Bypass, rose to 68.1 decibels after midnight, while the level was 29 decibels at 10 pm. The limit for residential areas during the night after 10 pm is 45 decibels and a 10 decibel increase in noise doubles the pressure on human ears. At midnight, New Market and Tollygunge — both commercial locations with nearby residential areas — recorded 84.8 and 84.5 decibels, respectively, at 12.30 am. The national limit is 55 decibels. Hospitals — designated silent areas where there is blanket ban on any firework bursting in a 100 metre radius — were not spared either. Noise levels ranging from 52 to 63 decibels were recorded near them even after midnight, against a national night-time limit of 40 decibels. The trend of complaints received by the state pollution control board and green platform Sabuj Mancha also corroborated the data, with more than 50 per cent complaints filed after 10 pm. Illegal fireworks dominated Illegal fireworks were being sold openly within bazi bazaars (firecracker markets) set up by the state government, found experts from Sabuj Mancha. While green crackers have logos and quick-response (QR) codes to verify their green status, the illegal ones manufactured with barium had fake QR codes. Most of the fireworks were brought from Sivakashi, Tamil Nadu as local production was minimal. “If illegal crackers were sold in markets set up by the government, one can imagine the state of the retail shops around the city and other districts, where there was hardly any monitoring,” alleged green activist Naba Dutta from Sabuj Mancha. “In Siliguri, we found fireworks with fake QR codes were sold everywhere,” said Animesh Bose from the non-profit Himalayan Nature and Adventure Foundation. The Sabuj Mancha team also found that some students at the Nil Ratan Sircar Medical College and Hospital were bursting fireworks within the hospital campus, most of which were illegal. High-rises hotbeds On Diwali night, the Sabuj Mancha team discovered that high-rises were the hotspot for violation. “We found that mainly shell fireworks have been burnt from the rooftops of high-rises,” said an activist. “The comparative high cost of green fireworks and the relative non-availability of local fireworks mean the affluent section of society was mainly responsible,” alleged a PCB official. “In my area, the violations mostly happened in high-rises,” admitted a senior police official from a south Kolkata police station. Slums, habitual violators, largely remained silent this year. As the violations increased over the Diwali evening — both the firework bursting and blaring loudspeakers — the administration was largely ineffectual. The police were not found to act on the ground to nab the violators, even in and around hospitals. The state PCB had several mobile teams on the ground and flew three drones in the city to identify the violators, but the exercise remained largely theoretical. “West Bengal used to have a 90 decibel maximum limit compared to 125 decibels in the rest of the country,” said Biswajit Mukherjee, former chief law officer of state PCB. “However, state PCB recently increased the maximum noise level to 125 decibels, so the message has gone across that the administration is no more serious about containing the noise and the violators got encouraged, resulting in both noise and air pollution.” We are a voice to you; you have been a support to us.

FG seeks more collaboration as 48 million Nigerians still engage in open defecation

The Federal government has called for more collective efforts among Nigerians to end open defecation as the number of Nigerians engage in the practice still remains at 48 million. The Minister of Water Resources and Sanitation, Prof. Joseph Utsev and his counterpart in the Environment, Mallam Balarabe Abbas made the call at a joint press briefing on thursday in Abuja to commemorate the 2023 world toilet day. They noted with regret that in Nigeria about 100 million persons lack access to basic sanitation,” while an estimated 48 million practice open defecation which put the country among the countries with the highest number of people involved in this practice.” According to water and sanitation Minister the practice of open defecation which is mostly due to the lack of sanitation facilities has a direct correlation with sanitation-related diseases, and also leading to poor educational outcomes and loss of productivity in the country. To tackle this water and sanitation crisis, Prof. Utsev said the government has initiated several interventions through the Water, Sanitation and Hygiene (WASH) programmes and projects targeted at accelerating progress towards national targets within the context of our global commitment in this Sector. The Minister listed some of the initiatives to include, the launch of the national action plan for the revitalization of the Sector and the Presidential declaration of a state of emergency in the sector. He said: “There is also the Partnership for Expanded Water, Sanitation and Hygiene (PEWASH) programme, the ‘Clean Nigeria: Use the Toilet’ Campaign and the Sustainable Urban and Rural Water, Sanitation and Hygiene Programme were also initiated.” Prof. Utsev who pointed out that access to adequate water, sanitation and hygiene (WASH) services is a critical factor for the socio-economic development of the country, besides the many other negative consequences such as the concomitant lack of dignity, inconvenience and violence experienced by women and girls, when practicing open defecation. While the environment Minister on his part also disclosed that, “The sanitation crisis poses a threat to our natural environment and the health of citizens, particularly women, girls and other vulnerable groups.” Mallam Abbas explained further that, “One of the major consequences of poor excreta and sewage disposal is the high rate of diarrhea disease which is the second cause of high morbidity and mortality rates among children under the age of five. “The persistent re-occurrence of annual incidences of cholera outbreaks in some of our states are also manifestations of inadequate toilet facilities. Yet this could also be prevented through safe excreta disposal by every individual.” According to environment Minister, in order to strengthen the capacity of the environmental health officers in the country , the Ministry has renewed a Memorandum of Understanding with the Centre for Science and Environment (CSE), India on technology transfer, technical assistance, capacity building and research development in areas of water, sanitation and environmental management.

New Delhi think tank partners with Uttar Pradesh government for safe sanitation on World Toilet Day

As the global community gears up to observe World Toilet Day on November 19, the Centre for Science and Environment (CSE), a prominent New Delhi-based think tank, took a stride towards reshaping India's sanitation landscape. In collaboration with the Department of Urban Development of the Uttar Pradesh government, CSE organised a workshop today aimed at advancing the urban sanitation agenda and promoting sustainable and inclusive septage management in the state. Depinder Singh Kapur, the Program Director for Water at CSE, said at the gathering during the workshop, emphasising the need to move beyond conventional toilets and focus on scaling up comprehensive septage management. The event, conducted in partnership with the Uttar Pradesh government, featured notable speakers such as Nitin Bansal, Director of Urban Local Bodies, UP, and P K Srivastava, Additional Mission Director, AMRUT, UP. Attended by officials from 17 municipal corporations, 56 Nagar Palika Parishads, and representatives from various government departments and missions, the workshop delved into critical issues surrounding sanitation. Among the publications unveiled on this occasion was the Septage Management Performance Assessment report covering 56 towns in Uttar Pradesh. A key focus of the workshop was the concept of 'aspirational toilets,' a facet introduced under India's Swachh Bharat Mission 2.0. These toilets aim to elevate standards in terms of cleanliness, hygiene, and user-friendliness. Discussions at the workshop ranged from quality and design to technology integration, accessibility, inclusivity, and sustainability. Safety for sanitation workers took centre stage, with the Uttar Pradesh government expressing its commitment to enhancing the well-being of its workforce. The implementation of 'Emergency Response Sanitation Units' in urban local bodies, aligning with the vision of 'manhole to machine hole,' aims to ensure the safety of sanitation workers. However, Kapur highlighted the challenge faced by households in smaller towns with narrow lanes, emphasizing the need to explore alternative options for mechanical emptying to ensure worker safety. The workshop also addressed the crucial issue of reusing bio-solids from treatment plants. CSE researchers stressed the importance of resource recovery to avoid exponential growth in bio-solids, which could lead to contamination and management issues. The results of a study analyzing sludge samples from 47 treatment plants, including those in Uttar Pradesh, were presented and discussed. Srivastava emphasized the importance of understanding the technical aspects of bio-solids and reuse standards, especially for non-technical personnel, to address the challenges of urban sanitation effectively. Nitin Bansal highlighted Uttar Pradesh's transition from achieving open defecation-free status to addressing broader goals, including sustainability of sanitation infrastructure, septage management, and the inclusion of women and marginalised communities. Depinder Singh Kapur commended the collaboration between CSE and the Uttar Pradesh government, dating back to 2015, and acknowledged World Toilet Day as a crucial occasion to accelerate safe sanitation initiatives throughout the entire sanitation value chain. Srivastava applauded CSE's efforts in supporting the state government in operationalising Faecal Sludge Treatment Plants (FSTPs) and in preparing bye-laws for urban local bodies, marking a significant step towards addressing the challenges of urban sanitation in Uttar Pradesh.

Move beyond toilets towards inclusive sanitation, says CSE on eve of World Toilet Day

As the world gets ready to mark World Toilet Day on November 19, New Delhi-based think tank Centre for Science and Environment (CSE) is offering a pathway towards reimagining India’s sanitation future. Speaking at a workshop on safe sanitation organised here today, Depinder Singh Kapur, programme director, water, CSE said: “This year, the theme for the World Toilet Day is accelerating change to solve the water and sanitation crisis. CSE, in partnership with the Uttar Pradesh government, come together for urban sanitation agenda forward and move beyond toilets – towards ensuring scaling up of sustainable and inclusive septage management in the state.” CSE organised today’s workshop in collaboration with the Uttar Pradesh government’s Department of Urban Development. Besides Kapur, the other speakers included Dr Nitin Bansal, IAS, director, Urban Local Bodies, UP and Dr P K Srivastava, additional mission director, AMRUT, UP. Participants included officials from 17 municipal corporations and 56 nagar palika parishads; state-level functionaries from various missions such as Swachh Bharat Mission, AMRUT, State Mission for Clean Ganga etc; and representatives from various related government departments. Among other publications, a Septage Management Performance Assessment report of 56 towns of Uttar Pradesh, was released on the occasion. One of the issues that the workshop focused on was that of ‘aspirational toilets’. Envisaged under India’s flagship programme, the Swachh Bharat Mission (SBM) 2.0, aspirational toilet is all about “raising the standards and aspirations regarding toilet facilities, aiming for higher levels of cleanliness, hygiene, and user-friendliness”, according to CSE researchers. The workshop discussed some key aspects of these toilets, ranging from quality, design and technology integration, to their accessibility, inclusivity and sustainability. Safety of sanitation workers was another discussion point at the workshop. The Uttar Pradesh government is keen to work on the safety and well-being of its sanitation workers and Safai Mitras to ensure improved livelihood options for them. In line with the Government of India’s vision of ‘manhole to machine hole’, all urban local bodies (ULBs) in the state have set up ‘Emergency Response Sanitation Units’ (ERSU) for ensuring safety of sanitation workers. ULBs are trying to ensure that all manholes/machine holes are cleaned only through mechanical machines and human entry in machine hole is not permitted. Kapur, however, pointed out that “households living in narrow lanes in small and medium towns are facing a challenge in emptying their septic tanks due to difficulties of access — there is, thus, a need to explore alternative options for mechanical emptying to ensure safety of sanitation workers.” The third key subject for deliberations at the workshop was reuse of bio-solids mined in treatment plants. Says Kapur: “India is in the midst of an urban sanitation revolution, where conventional systems of water-based centralised sewerage, designed to transport faecal material from homes through pipes to sewage treatment plants, are being augmented with non-sewered sanitation systems of faecal sludge treatment plants (FSTPs), that are designed to cater to towns and parts of cities where sewerage systems don’t exist.” The challenge is to ensure resource recovery from the faecal sludge or bio-solids in the treatment plants. CSE researchers point out that if this is not done, “the quantity of bio-solids will grow exponentially and will add to problems of contamination and management in the plants”. Working towards finding an answer to the challenge, CSE has collected and analysed sludge samples from 47 FSTPs and co-treatment STPs in seven states, including Uttar Pradesh. The results of the analysis were also discussed at the workshop. The CSE study results showed that FSTPs perform as effectively as conventional STPs, in terms of reducing BOD levels in treated wastewater, meeting the standards. CSE researchers say the challenge is in securing adequate sludge reaching the FSTPs, and effective operations and maintenance. Faecal coliform remains an issue of concern, despite UV treatment at the tertiary level. COD treatment standards are not being met by most FSTPs. However, this is an issue for most STPs in India. Speaking on the issue, Dr Srivastava said: “It is important to understand the technical aspects of bio-solids and reuse standards. This is especially critical for non-technical persons like executive officers and commissioners to enable them to advocate for and implement solutions for addressing second generation challenges of urban sanitation – the reuse of wastewater and bio-solids.” Addressing the gathering, Dr Nitin Bansal said: “From our target of making UP open defecation free, we have now moved towards higher goals – ranging from ensuring sustainability of sanitation infrastructure, addressing septage management, upgrading public toilets, and focusing on inclusion of women and marginalised communities on a priority basis. To do all this, the state government is working together with its partners, including CSE.” Throwing light on the collaboration between CSE and the state government, Kapur said: “Since 2015, CSE has been supporting the Department of Urban Development in Uttar Pradesh and the National Mission for Clean Ganga to address the used water and septage management challenges in UP. Together, we recognises World Toilet Day as an important occasion for initiating as well as culminating actions for accelerating safe sanitation initiatives — not limiting to only to only initiatives around toilets but addressing the whole sanitation value chain, from containments to emptying and transportation to treatment and reuse.” Dr Srivastava commended the efforts made by CSE to support the state government in operationalising the FSTPs and in preparation of the bye-laws for urban local bodies.

NO2 levels nearly 3X higher than safe limit this mth so far, says CPCB data

Gurgaon: The concentration of nitrous dioxide (NO2) in the city’s air has seen an increase between November 1 and 16 with the rise in pollution, breaching the permissible limit at some spots in the city several times. With civic agencies focussing mitigation measures on cutting PM2.5 and PM10 (ultrafine particles) emissions, the concentration of nitrogen oxides (NOx) such as NO2 in the city’s air has largely gone under the radar, despite their levels being nearly thrice the global safe standards, according to data from the Central Pollution Control Board’s (CPCB) pollution monitoring stations across the city. The CPCB has set an annual average limit of 40 µg/m³ for NO2 in the country, while the WHO’s safe limit for NO2 is 25 µg/m³. But at the Sector 51 air monitoring station, the average NO2 concentration at ground-level or tropospheric ozone was 87 µg/m³ on November 1, 97µg/m³ on November 2, 115 µg/m³ on November 3, 162 µg/m³ on November 5 and 87 µg/m³ on November 15. At Gwalpahari station, it was recorded at 115 µg/m³ on November 8 and 114 µg/m³ on November 12. The NO2 levels at Vikas Sadan and Teri Gram were within the safe limit (see graphic). Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease. It may also affect the senses, for example, by reducing a person's ability to smell an odour. High levels of nitrogen dioxide are also harmful to vegetation. According to experts, vehicular emissions are the primary source of NO2 in the city. The Sector 51 station covers the most polluted localities in Gurgaon even in terms of the average AQI, PM2.5 and PM10 levels, apart from NO2, primarily due to the large number of housing societies, vehicular congestion, urban slums, broken roads and construction dust. NO2 and other NOx react with other chemicals in the air to form both particulate matter and ozone. The reactions can also lead to the formation of acid rain, which can harm sensitive ecosystems such as lakes and forests, experts said. The major sources of NO2 are on-road transportation, coal-based energy production and industrial processes. “The high NO2 levels in the city are mainly due to vehicular emissions. Old vehicles and traffic congestion are the key sources of NO2 here. It has been observed that during winter, the air quality oscillates between ‘very poor’ and ‘severe’ as the condensation of fine particulate matter in the lower layer of the atmosphere,” said Shubhansh Tiwari, a research associate at the Centre for Science and Environment. Asked if the authorities are taking any steps to reduce NO2 emissions, the Haryana State Pollution Control Board (HSPCB) said all agencies are actively taking steps to ensure traffic congestion doesn’t occur in the city. “We have also given NOC to a private firm in Manesar to scrap old vehicles. This aims to remove polluting vehicles from the city roads," said Vijay Chaudhary, HSPCB regional officer (Gurgaon). Experts warned that long-term exposure to high NO2 levels causes asthma and increases susceptibility to respiratory infections. People with asthma, as well as children and the elderly are generally at greater risk. “Nitrogen is present in the air in the forms of nitrous oxide, nitric oxide and nitrogen dioxide. Chronic exposure to high concentrations of NO2 can cause alterations to lung metabolism, structure and function, inflammation and increased susceptibility to pulmonary infections and subsequent development of COPD,” said Dr Tushar Tayal, lead consultant (internal medicine) at CK Birla Hospital.

WFH, odd-even: Highest pollution curbs in place in Delhi, no measures on ground

Letting public, municipal and private offices work on 50% strength and the rest to work from home; closure of colleges and “non-emergency commercial activities,”; allowing vehicles to run on odd-even basis — it has been 11 days since Stage IV of the Graded Response Action Plan (GRAP) was imposed, but these measures are yet to be enforced. This, even as Delhi’s air quality deteriorated further on Thursday — the AQI was 440 (‘severe’) at 10 pm. This is also the longest stretch for which the most extreme restrictions under the plan have been suggested, at least from 2021 onwards. Last year, Stage IV — which comes into force when AQI levels are over 450 or the ‘severe plus’ category — was invoked by the Commission for Air Quality Management (CAQM) on November 3 and revoked three days later. In 2021, it was invoked on November 3 and revoked on November 7. The Act that constituted the CAQM for the NCR was passed in 2021. While it takes decisions on imposing stages of GRAP in the NCR, the steps are to be implemented by state governments. While the odd-even scheme has not been implemented in the city after an attempt in 2019, work-from-home for 50% of Delhi government staff was announced in November last year. The Delhi government had earlier announced that the odd-even scheme would kick in from November 13 to 20, only to defer it after the Supreme Court had referred to it as “optics.” When contacted for a comment, the office of Environment Minister Gopal Rai said measures such as the odd-even scheme and 50% work from home in private and government offices are under consideration for implementation subject to the AQI reaching the ‘severe plus’ (more than 450) category. The transport sector, meanwhile, continues to remain a large contributor to PM 2.5 levels in the city, going by data from IIT-Kanpur’s real-time source apportionment study. At 38%, it was the single largest contributor to PM 2.5 levels in the city on Wednesday, followed by 30% from secondary aerosols, and 23% from biomass burning. Anumita Roychowdhury, Executive Director, Research and Advocacy, Centre for Science and Environment (CSE), said, “Evidently, restrictions are applied keeping in mind public reaction. On some measures, there is hesitation to implement action more aggressively. Some restrictions are in place, but keep in mind that at this moment, vehicles are the major contributor to pollution, so when you do have a smog episode, reducing the sheer volume of vehicles on the road is critical. That needs to be addressed during a severe smog episode, and they would have to find ways of dealing with it and implement measures that have already been included.” Meanwhile, Rai Thursday said a six-member special task force, including officials of the environment department, Traffic Police, MCD and PWD, has been constituted to implement GRAP-related restrictions.

Delhi, Greater Noida Top NCR's Pollution Chart So Far This Month

Comparing Delhi's average AQI for the period of November 1–16 against that of 17 other NCR towns and cities—including Noida, Gurgaon, Greater Noida, Ghaziabad, Jind, and Rohtak—we found that Delhi's average was the lowest at 378. New Delhi: According to data from the Central Pollution Control Board (CPCB), Delhi experienced its eighth "severe" air day of the month, making it the most polluted of the 18 major NCR towns and cities so far this month. The overall air quality index (AQI) in Delhi stood at 404 as per the latest data from SAFAR (System of Air Quality and Weather Forecasting and Research)-India. Based on the CPCB's 4 pm bulletins, AQI averages for November thus far indicate that Greater Noida has an average AQI at 367 after Delhi's average AQI, followed by Faridabad at 366, Jind at 344, Noida at 343, Gurgaon at 328, Meerut at 325, and Rohtak and Sonipat at 323. “If you consider the landscape of NCR and Delhi, Delhi becomes the epicentre of the problem given the sheer size and demography, and concentration of activity. This is a combination of Delhi’s own very high local pollution and this being aggravated by regional influence. This means Delhi has to do more to be able to control pollution and its own action needs to get deeper, but action will also have to be tightened across NCR,” said Anumita Roychowdhury, Executive Director, Research and Advocacy, Centre for Science and Environment, as quoted by The Indian Express. Region-Wise AQI Level in parts of Delhi on Friday As of 8 am, the air quality in Delhi's Anand Vihar stood at 448; in Dwarka Sector-8, the AQI fell under the severe' category with an AQI of 491; meanwhile, in the IGI Airport (T3) area, the AQI stood at 465; while Mundka at 483. AQI in Gurugram In the Sector-51 area, the AQI was at 441. In the Teri Gram area, the AQI fell under the very poor' category, while in Vikas Sadan, the AQI was recorded at 393. AQI in Faridabad In Faridabad's New Industrial Town, the AQI stood at 411, while in Sector-11 region, the AQI fell under the 'severe' category. With respect to Sector-30, the AQI stood at 392. AQI in Ghaziabad In Indirapuram, the AQI stood at 401 while in the Loni region, the AQI fell under the 'very poor' category. In Sanjay Nagar, the AQI was recorded at 317 while Vasundhra region recorded an AQI of 384. Noida's AQI With respect to Sector-125, the AQI fell under the ' very poor' category, while Sector-62 recorded an AQI of 370. In Sector-1, the AQI fell under the 'very poor' category. Greater Noida's AQI The AQI level in the Knowledge Park-3 region was recorded at 311 which falls under the 'very poor' category.

Stark rise in farm fires in past few days, delayed harvesting to blame

NEW DELHI: Daily stubble burning instances in Punjab have shown no sign of decreasing yet, although, in previous years the count had dropped after November 15. On the contrary, Punjab recorded 1,776 incidents on Tuesday, 2,554 on Wednesday and 1,271 on Thursday. When compared with figures earlier in November — 639 instances on November 9, 6 on November 10, 104 on November 11 and 987 on November 12 — the rise this week is significant. delayed harvesting Experts said that due to delayed harvesting this year, the concentrated burning of crop residue was happening now. Fire counts are likely to be on the higher side for a week, they said. Satellite data compiled by Indian Agricultural Research Institute (IARI) shows that daily stubble burning in 2022 was less than 1,000 from November 17 onwards and dipped to below 100 on November 24. Similarly, in 2021, the per day counts stayed below 1,000 from November 17 and dropped to below 100 on November 22. Anumita Roychowdhury, executive director of research and advocacy at the Centre for Science and Environment, said: “This spike in stubble burning count in the last three days indicates late harvesting of crops in some areas and delayed burning due to rain and Diwali. This led to concentrated burning in a short time span afterwards.” Gufran Beig, chair professor in the National Institute of Advanced Studies (NIAS) and founder of the System of Air Quality and Weather Forecasting and Research (SAFAR), said: “The area of cultivation remains the same and harvesting started late this year and hence stubble burning counts were low in October. However, peak burning has not yet started, and it is likely to happen next week. As the new crop will be sown by the first week of December, farmers will be in a hurry to empty the field. This is more dangerous as we are extending the burning period by around 10 to 15 days. This may result in more days with AQI in the upper end of ‘very poor’ or severe days in comparison to last year.” The cumulative count compared to the past four years is the lowest in Punjab so far this season. From September 15 to November 16, Punjab has witnessed 31,932 stubble burning counts, when it was 46,822 in 2022. In the same period, Haryana recorded 1,986 farm fires in 2023 and 3,233 in 2022. In contrast, UP has seen a rise in burning instances. UP recorded 2,113 crop residue burning incidents from September 15 to November 16 in 2023, against 1,505 in 2022, the IARI data shows. The IARI follows the notified standard of the Commission for Air Quality Management in national capital region and adjoining areas.

Can India sustainably manufacture and recycle EV batteries?

The adoption of electric vehicles (EVs) is witnessing a swift expansion around the globe, driven by the growing emphasis of governments and demand from consumers for low-emission transportation options. India, a rapidly emerging market for EVs, currently has over 2.3 million EV users. In the financial year 2022-23, India’s annual EV sales surpassed 1.2 million, marking a 174% increase from the previous year. More than 60% of these sales were electric two-wheelers, while passenger electric three-wheelers accounted for 29% of the total units sold, as reported in the Annual India EV Report Card published earlier this year by consulting firm, JMK Research. More than half of the three-wheelers registered in India in 2022 were electric, according to an International Energy Agency (IEA) report published in April. India is rapidly adopting electric vehicles (EVs) with annual sales exceeding 1.2 million in 2022-2023. However, this surge raises concerns about the life and demand of EV batteries. India currently relies heavily on imports for lithium-ion EV batteries. However, there is a growing push to support domestic EV industry development, thereby fostering economic growth and job opportunities. Materials from old EV batteries can be extracted through the recycling process, but battery recycling is highly capital-intensive and there is no existing market guide pricing and supply-demand dynamics. India must therefore, address these gaps to start recycling EV batteries at a large scale. As the use of EVs grows around the world, there is also a growing need for EV batteries. This demand has led to significant growth in battery production. By 2030, it’s expected that there will be over five terawatt hours (TWh) of gigafactory capacity globally each year. ‘Gigafactory’ is a term popularised by the automobile company Tesla, which essentially means a large-scale EV battery manufacturing facility. For context, the country Senegal consumed about five terawatt hours (5,300 gigawatt hours per year) of electricity in 2021. India’s electricity consumption was around 1400 terawatt hours (1,442,000 gigawatt hours per year) as of 2021. EVs are powered by lithium-ion (Li-ion) batteries. Therefore, with the increasing demand for EVs, the demand for Li-ion batteries is also set to increase. In 2021, the global lithium market was valued at $6.83 billion and it is projected to grow at an annual rate of 12 percent from 2022 to 2030. As of 2021, the global lithium production amounted to 100,000 tonnes (equivalent to 90.7 million kilograms), while the worldwide reserves are estimated to be around 22 million tonnes (equivalent to 20 billion kg), according to data from the U.S. Geological Survey. Priti Mahesh, the Chief Program Coordinator of the non-profit Toxics Link, told Mongabay-India, “With such rapid growth expected in the global lithium market, it’s important to understand the necessary materials for the production of EV batteries, its battery recycling market and how this will impact the future of EV batteries.” What are the components of a Li-ion battery? Electric vehicle batteries come in different configurations, encompassing various shapes and sizes. Manufacturers have a multitude of choices when it comes to battery design, spanning from the physical structure of the cells to their chemical composition. Batteries can be categorised into two main groups – primary batteries (also known as single-use batteries), which cannot be recharged and secondary batteries, which are rechargeable. Lithium-ion batteries belong to the latter category, as they can be charged and reused multiple times. Explaining the composition and structure of lithium-ion batteries, Mahesh states, “In addition to lithium, a lithium-ion battery contains various other components and the manufacturing process involves multiple layers. Like most batteries, lithium-ion batteries consist of a positively charged cathode, a negatively charged anode, and an electrolyte that separates them. Typically, the cathode is composed of a mixture of lithium, nickel, cobalt, and manganese, while graphite is the most common choice for the anode. To protect and hold the individual cells together, lithium-ion batteries are enclosed in either an aluminium or steel casing, safeguarding them against mechanical damage.” EV batteries typically consist of hundreds of cells, allowing each battery pack to maintain its charging and discharging capabilities for a range of 100,000 to 200,000 miles (1,60,934 to 3,21,868 kilometres), shares Mahesh. This confidence in battery durability is reflected in manufacturers’ common practice of offering extended warranties, often covering eight years or 100,000 miles for their electric vehicles (EVs). Typically, automobile Original Equipment Manufacturers (OEMs) such as Ola Electric and Ather Energy provide a standard three-year warranty for the batteries in their EVs. However, these batteries can potentially exceed this warranty period and last up to five years or more, contingent on factors such as usage patterns, environmental conditions and the effectiveness of the battery charging process. Batteries used in two and three-wheelers are generally designed to withstand approximately 2,000 cycles of charging and discharging. In cases where EVs are employed for commercial purposes, the battery may wear out in as little as two years. Private vehicle batteries tend to have a longer lifespan, but for those engaging in extended journeys, battery replacement may become necessary within three years. Moreover, current EV batteries have a lifespan of approximately 15 to 20 years within the vehicle, and they may even have a second life after this initial period. This extended longevity is complemented by ongoing advancements in EV battery technology, which are expected to result in batteries that last even longer, while also becoming more cost-effective, smaller in size and easier to transport. Can India become self-reliant in EV battery manufacturing? India’s ambition to expand its EV programme and bolster domestic manufacturing faces a significant challenge in ensuring a stable supply of raw materials for battery cells. At present, India heavily relies on imports, primarily from China, for Li-ion batteries and cells due to limited local cell manufacturing. Rishabh Jain, Senior Programme Lead at The Council on Energy, Environment and Water (CEEW), elaborates, “This dependence on imports makes India’s EV industry vulnerable to global supply chain uncertainties and risks. However, there is a growing push to reduce import reliance and promote self-reliance to keep more of the value chain within India, thereby fostering economic growth and job opportunities. Policy initiatives like the Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles (FAME II) scheme and the Production-Linked Incentives (PLI) scheme are designed to support domestic industry development. FAME II encourages EV equipment manufacturers to source at least 50% of their components locally, while the PLI scheme targets Advanced Chemistry Cell (ACC) manufacturers.” To address material security, India is also focusing on expanding mining exploration both within the country and overseas. India has joined the Minerals Security Partnership (MSP), a global alliance led by the United States, to catalyse investment in critical mineral supply and value chains. These strategies aim to increase domestic battery availability, reduce imports and lower battery costs while ensuring access to key raw materials like lithium, nickel, cobalt, and manganese, which constitute a significant portion of cell costs. A CEEW study, titled How can India Indigenise Lithium-Ion Battery Manufacturing? authored by Rishabh Jain, highlights the critical importance of India gaining more control over the supply chain of lithium-ion batteries. Jain emphasises that considering the complexity of the global supply chain, it becomes imperative to develop an energy storage ecosystem, scale up battery cell manufacturing, and stabilise it to align with India’s decarbonisation objectives. “Additionally, the focus should be squarely on battery recycling as a means to reduce the demand for new minerals,” he adds. Can EV batteries be recycled to mine minerals? When we are producing so many batteries already, can the minerals locked inside the batteries be extracted to produce new batteries? Anumita Roy Chowdhury, Executive Director at the Centre for Science and Environment (CSE), believes this is possible. Studies on a global scale have shown that the material trapped inside batteries can have infinite utility if efficiently extracted, separated, and recycled. “So, when the batteries are no longer suitable for vehicles, the first thing to do is to reuse them in some other application. Then, when the batteries have reached the end of their life, take them back and extract all that material,” she elaborates. Global estimates, including those from the International Council on Clean Transportation (ICCT), suggest that approximately 50 percent of spent battery materials can potentially be mined, presenting an opportunity to significantly reduce the annual demand for these minerals by up to 28 percent over the next two decades (2050). In India, NITI Aayog forecasts that by 2030, there could be as much as 128 gigawatt-hours of recyclable batteries available, with EV batteries constituting 46 percent of this total. India’s current recycling capacity stands at a modest two gigawatt-hours approximately and it would have to increase about 60 times in the next eight years.

印度德里為何在消除霧霾之戰中落後於北京

長期以來,生活在人口稠密的兩個亞洲國家首都的人們,都飽受籠罩其城市的有毒霧霾之苦。 德里和北京都是人口超過2000萬人的繁華都市。在某些日子裏,當它們被霧霾所籠罩,呈現出橙灰色的天際線並彌漫著煙味時,人們說感覺就像生活在一場反烏托邦的夢魘中。北京居民甚至將毒霧稱為「空氣末日」。 如今,德里又來到了一年中的霧霾季,而北京的空氣質量已經好得多。 PM2.5是一種小到可以深入肺部的顆粒物,它們和多種氣體的混合物在內陸城市德里遮天蔽日,使其成為世界上污染最嚴重的城市之一。低風速將污染物截留在低層大氣中,使空氣質量惡化。 當局暫時關閉學校、命令柴油車禁止上路、停止建築施工、要求人們在家工作,以及禁止燃放鞭炮。在印度混亂的民主制度下,這些措施很難執行。居民們咳嗽、喘息、憤怒,生活仍在繼續。 一系列指揮和控制措施幫助北京淨化了空氣。 周一,印度教節日排燈節過後的清晨,狂歡者不顧禁令燃放鞭炮,德里成為世界上污染最嚴重的城市之一。一款政府應用程序顯示,周一上午,一些地方的空氣質量指數(AQI)攀升至520以上(數字低於50為良好)。 同日上午,北京的天空更加湛藍,空氣質量指數不到德里的五分之一。自2013年以來,北京乃至整個中國都通過一系列指揮和控制措施,對空氣污染髮起了一場堅決的戰爭。 一項雄心勃勃的行動計劃限制了新增煤炭產能、關閉居民樓內以煤炭為燃料的供暖系統、提高柴油卡車的燃料和發動機標凖、淘汰污染嚴重的老舊汽車……當局還鼓勵人們在短途通勤時改用電動汽車或騎自行車。 總部位於赫爾辛基的能源與清潔空氣研究中心(CREA)首席分析師柳力(Lauri Myllyvirta)表示,北京曾努力提高市內的空氣質量,但過去十年的顯著改善來自於其將工作範圍擴大到了城市之外。 他表示,通過建立一個覆蓋城市以外的產業集群和主要排放源的「重點控制區」,當局取得了更具影響力的成果。北京治理空氣污染的預算從2013年的4.3億美元(3.5億英鎊)躍升至2017年的26億多美元。 結果令人印象深刻。根據芝加哥大學能源政策研究所編製的空氣質量生活指數(Air Quality Life Index),自2013年以來,北京的空氣污染下降了約50%,全國範圍下降了約40%。 「北京曾在(空氣污染指數)中位居前列,但現在已經有了顯著改善。人們大力推動從煤炭向天然氣和可再生能源轉變。購買電動汽車比購買汽油車更容易。」《經濟學人》智庫(EIU)中國分析師李子謙(Chim Lee)告訴我。 專家們承認,德里20年來改善空氣質量的努力也取得了一些成果。該市淘汰了污染嚴重的行業、關閉了燃煤電廠、推出了全球規模最大的天然氣公共交通項目、強制淘汰老舊商用車、制定了更嚴格的排放標凖,並建設了高效的地鐵。 這些措施是否影響了德里的空氣質量?空氣污染專家、德里科學與環境中心執行總監阿努米塔·羅伊喬杜里(Anumita Roychowdhury)給出了肯定的答覆。 「德里長期的空氣質量趨勢顯示其水平並沒有逐年上升。實際上它正在下降。這意味著德里已經穩定了問題,並扭轉了污染曲線。但這也意味著德里需要將PM2.5水平再降低60%,才能達到潔淨空氣標凖。」她告訴我。 然而,由於規劃不足、政策設計缺陷和黨派政治,德里與空氣污染的鬥爭步履蹣跚。 研究表明,德里一半以上的污染來自車輛排放,其次是燃煤工業產生的煙塵、垃圾焚燒和建築工地的灰塵。 冬季來臨,鄰近的旁遮普邦和哈里亞納邦在收獲季節焚燒秸稈是一種常見的做法。在某些日子裏,根據風速和風向的不同,焚燒秸稈造成的空氣污染可構成德里空氣污染的四分之一。 印度總理納倫德拉·莫迪(Narendra Modi)領導的印度人民黨(BJP)政府現在指責由反對黨執政的旁遮普邦未能解決該問題。 通過禁止老舊車輛上路,德里已將道路上的汽車數量減少了近800萬輛,比2015年減少了三分之一以上。 然而,汽車尾氣排放仍然是造成德里污染的主要原因,因為這座城市的設計更偏向於汽車,而不利於行人和騎自行車的人。 全長近400公里(248英里)的德里地鐵是印度最長、最繁忙的地鐵網絡,但通往家庭和工作場所的最後一公里路仍然不暢。雖然全市7000輛公交車中約有14%是電動車,但諷刺的是由於使用不便,公交車的乘坐率卻在下降。 儘管德里總體規劃的目標是80%的機動出行由公共交通承擔,但地鐵和公交系統之間缺乏整合阻礙了這一目標的實現。 「即使有了解決方案,你也無法使它發揮作用,因為設計不合理。」羅伊喬杜里說。 缺乏區域性的規劃也阻礙了空氣改善。當人們圍繞德里的污染問題展開討論時,廣袤的印度河-恆河平原(橫跨印度北部、巴基斯坦東部、尼泊爾和孟加拉國部分地區)上的鄰近城市也被煙霧籠罩。 研究表明,比哈爾邦的空氣污染水平經常高於德里,但有關這一問題的討論卻十分有限。「對話不能只是關於德里,必須擴大到整個地區。」羅伊喬杜里補充道。

Opinion: India’s chain-smoking states - Pollution is not Delhi’s problem alone

Every winter, when air pollution spikes, Delhi typically hogs the limelight as the epicentre of the problem. But Delhi is not alone in this pollution battle. The entire Indo-Gangetic Plain (IGP), encompassing not just cities but also towns and rural settlements, finds itself enveloped in a blanket of smog. This occurs when cool and calm weather conditions trap dangerous levels of air pollution close to the ground level in the landlocked region of Northern India. In winter, several cities and towns in the Indo-Gangetic Plain experience average levels of particulate matter less than 2.5 micron in size (PM2.5) which is worse than Delhi. PM2.5 are tiny toxic particles that can penetrate deep into our lungs and enter the bloodstream, posing a significant health risk. An analysis by the Centre for Science and Environment (CSE) shows that during the winter of 2022-23 (from October to February), at least 10 lesser-known towns of Bihar had average winter PM2.5 levels that were substantially worse than that of Delhi. These included Begusarai, Siwan, Darbhanga, Katihar, Purnia, Saharsa, Chapra, and Bhagalpur. While Delhi’s winter average hovered around 152 micrograms per cubic meter, these cities experienced a range from 163 to 283 micrograms per cubic meter. This highlights the rapid build-up and peaking of pollution across the Indo-Gangetic Plain within a short timeframe, engulfing both large and small cities, as well as rural settlements. The combination of winter inversion, slower wind patterns, intense local pollution from local and regional sources and the diverse impacts of episodic farm fires contribute to this complex scenario. When the entire region is covered in a blanket of smog, all human settlements get affected. Even smaller towns such as Sirsa, Jind, Karnal, Bathinda, Meerut, and stretching further to Lucknow, Varanasi, Patna, and Gaya, along with cities of West Bengal at the fringe of the Indo-Gangetic Plain, are vulnerable to regional pollution and smog episodes. Many of these cities and towns, despite having much lower annual average levels of PM2.5 compared to Delhi and several bigger cities, still experience significantly high daily pollution levels during winter. Not just a local problem Clearly, air pollution has no boundaries and is not a problem in any one city. Air and pollution move across administrative boundaries with strong local impacts. In Delhi, the hourly forecast of the contribution of different sources to Delhi’s air quality by the Decision Support System of the Indian Institute of Tropical Meteorology reveals a high impact of pollution from NCR -- averaging close to half or more. This fact is further underscored by the 2018 pollution source assessment conducted by the Automotive Research Association of India and the Energy Resource Institute for Delhi. Throughout the year, the contribution of the NCR to Delhi’s PM2.5 level is about 23-24 per cent. Delhi’s own contribution to NCR towns such as Noida can also be high -- as much as 28 per cent during summer and 40 per cent during winter. This demands massive clean-up across all regions to meet clean air benchmarks and prevent deadly smog episodes.

दुनिया के सबसे खराब वायु गुणवत्ता संकट से निपटने के लिए दिल्ली बारिश के समाधान पर विचार कर रही है।

Delhi: प्रदूषण के बढ़ते स्तर के खिलाफ लगातार लड़ाई में, दिल्ली सरकार एक अनूठी रणनीति तलाश रही है: क्लाउड-सीडिंग के माध्यम से बारिश कराना। इस पहल का उद्देश्य न केवल दिल्ली बल्कि व्यापक राष्ट्रीय राजधानी क्षेत्र (NCR) और उत्तरी भारत के व्यापक क्षेत्रों में फैले जहरीले धुएं को धोना है। दिल्ली के पर्यावरण मंत्री गोपाल राय ने सतर्क आशावाद व्यक्त करते हुए कहा कि अगले दो से तीन दिनों में स्थिति की निगरानी के बाद कृत्रिम बारिश पर निर्णय लिया जाएगा। भारत में इस अप्रयुक्त दृष्टिकोण ने विशेषज्ञों से संदेह पैदा किया है, जिसमें एक सलाहकार मोहन पी. जॉर्ज भी शामिल हैं विज्ञान और पर्यावरण केंद्र के लिए। जॉर्ज ने दिल्ली के आसमान में क्लाउड-सीडिंग के लिए उपयुक्त क्लाउड फॉर्मेशन की कमी के बारे में चिंताओं पर प्रकाश डाला और इसकी प्रभावशीलता पर संदेह जताया। संभावित सीमाओं के बावजूद, सरकार वायु प्रदूषण के गंभीर मुद्दे के समाधान के लिए विभिन्न रास्ते तलाश रही है। स्विस वायु निगरानी कंपनी IQI Air के अनुसार, दिल्ली में वर्तमान परिदृश्य गंभीर है, शहर ने हाल ही में दुनिया की सबसे प्रदूषित राजधानी होने का संदिग्ध गौरव अर्जित किया है। घनी आबादी वाला क्षेत्र, जिसमें दिल्ली और उसके विशाल उपनगर शामिल हैं, जिसे एनसीआर के रूप में जाना जाता है, लंबे समय से खतरनाक वायु गुणवत्ता स्तर से जूझ रहा है। जबकि दिल्ली अक्सर अपनी राजधानी की स्थिति और राष्ट्रीय प्रेस कार्यालयों की सघनता के कारण सुर्खियों में रहती है, प्रदूषण संकट शहर की सीमाओं से कहीं आगे तक फैला हुआ है। एनसीआर एक विस्तृत क्षेत्र में फैला है, जिसमें गुरुग्राम, फ़रीदाबाद, नोएडा, ग़ाज़ियाबाद और यहां तक ​​कि मेरठ भी शामिल है। प्रदूषण के बादल राजनीतिक सीमाओं तक नहीं रुकते, उत्तर भारत के अधिकांश हिस्से को अपनी चपेट में ले चुके हैं, पाकिस्तान के लाहौर तक पहुँच चुके हैं और पटना तथा कोलकाता जैसे क्षेत्रों के लिए खतरा बढ़ रहा है। पृथ्वी विज्ञान मंत्रालय की रिपोर्ट के अनुसार, दिल्ली में वायु प्रदूषण के स्रोत बहुआयामी हैं, जिसमें वाहन उत्सर्जन का योगदान 41%, सड़कों, निर्माण और विध्वंस से निकलने वाली धूल का योगदान 21.5% और उद्योगों का योगदान 18% है। थर्मल प्लांटों को बंद करने, ट्रकों पर प्रतिबंध और स्वच्छ ऊर्जा स्रोतों में बदलाव सहित ठोस प्रयासों के बावजूद, प्रदूषण का स्तर बना हुआ है और दिवाली जैसे विशिष्ट आयोजनों के दौरान यह और भी खराब हो गया है। एक महत्वपूर्ण चुनौती दिल्ली का भौगोलिक और जनसांख्यिकीय विस्तार है, जो इसे प्रदूषण के जाल के प्रति संवेदनशील बनाता है और प्रभावी समाधान लागू करने की कठिनाई को बढ़ाता है। पर्यावरणविद इस बात पर जोर देते हैं कि प्रदूषण नियंत्रण उपायों का विस्तार दिल्ली से आगे बढ़कर पूरे उत्तरी क्षेत्र तक होना चाहिए। सेंटर फॉर साइंस एंड एनवायरनमेंट में अनुसंधान और वकालत की कार्यकारी निदेशक अनुमिता चौधरी का कहना है कि लाहौर से ढाका तक फैले भारत-गंगा के मैदान में प्रदूषण का लगातार प्रसार देखा जा रहा है, जो पटना जैसे शहरों को प्रभावित कर रहा है और संभावित रूप से आगे बढ़ रहा है। हवा की गुणवत्ता में सुधार के लिए दिल्ली के प्रयासों में कोयला बिजली संयंत्रों को बंद करना, स्वच्छ परिवहन विकल्प अपनाना और प्रदूषण फैलाने वाले उद्योगों को प्रतिबंधित करना शामिल है। हालाँकि, उप-शहरों में शहर के विस्तार के कारण प्रदूषण फैलाने वाले उद्योग और थर्मल पावर स्टेशन फिर से उभर आए हैं, जिससे स्थिरता के लिए नई चुनौतियाँ पैदा हो गई हैं। वाहन प्रदूषण एक प्राथमिक चिंता बना हुआ है, जो दिल्ली के प्रदूषण संकट का एक महत्वपूर्ण हिस्सा है। हालांकि कई उपाय लागू किए गए हैं, जैसे सार्वजनिक और वाणिज्यिक परिवहन में संपीड़ित प्राकृतिक गैस (सीएनजी) और तरलीकृत प्राकृतिक गैस (एलएनजी) की ओर बदलाव, सड़कों पर वाहनों की भारी संख्या एक चुनौती बनी हुई है। राष्ट्रीय राजधानी क्षेत्र और आसपास के क्षेत्रों में वायु गुणवत्ता प्रबंधन आयोग के प्रमुख के रूप में दिल्ली के पूर्व मुख्य सचिव एम. एम. कुट्टी की नियुक्ति विभिन्न राज्य सरकारों के बीच समन्वित प्रयासों की आवश्यकता को रेखांकित करती है। हालाँकि, इन क्षेत्रों के बीच राजनीतिक विविधता प्रभावी सहयोग के लिए एक कठिन चुनौती प्रस्तुत करती है। जबकि दिल्ली और एनसीआर में 44 निरंतर निगरानी स्टेशनों के साथ प्रदूषण की समस्या की बड़े पैमाने पर निगरानी की गई है, प्रदूषण नियंत्रण के लिए एक क्षेत्रीय दृष्टिकोण की आवश्यकता तेजी से स्पष्ट होती जा रही है। प्रयासों की एकाग्रता ने दीर्घकालिक प्रदूषण वक्र को स्थिर कर दिया है, लेकिन प्रदूषण के स्तर में 60% की कमी हासिल करना एक कठिन कार्य बना हुआ है। निष्कर्षतः, दिल्ली और उत्तरी क्षेत्र में प्रदूषण के खिलाफ लड़ाई एक व्यापक, बहुआयामी दृष्टिकोण की मांग करती है, जो राजनीतिक सीमाओं को पार करती है और सार्वजनिक चेतना में एक आदर्श बदलाव लाती है। जबकि बारिश पैदा करने जैसे अपरंपरागत समाधान विचाराधीन हैं, स्वच्छ हवा की राह के लिए सामूहिक कार्रवाई, सख्त प्रवर्तन और सभी क्षेत्रों में स्थायी प्रथाओं के प्रति प्रतिबद्धता की आवश्यकता है।

Ensure Adequate Hygiene, Safe Toilets By 2030, FG Tasks Stakeholders

In a collaborative effort between the Federal Ministry of Environment (FME) and the Federal Ministry of Water Resources and Sanitation (FMWR&S), stakeholders and the public have been tasked with accelerating efforts to ensure that every Nigerian has access to adequate hygiene and safe toilets by 2030. During the press briefing for the 2023 World Toilet Day (WTD) in Abuja, titled ‘Accelerating Change,’ the Minister of the Federal Ministry of Environment, Malam Balarabe Abbas highlighted that the issues of open defecation in Nigeria are no longer acceptable. He emphasised that sanitation is a human right, and access to these services is crucial for people’s health, business, and the environment. The theme for this year’s World Toilet Day, “Accelerating Change,” aims to inspire individuals to take personal action in improving toilets and sanitation systems. Abbas stressed that every sector and every Nigerian has a role to play in addressing the sanitation crisis. Toilets, according to Abbas, are fundamental to public health, playing a crucial role in protecting the environment by removing human waste away from homes hygienically. However, he lamented that toilets and the supporting sanitation systems are neglected in many parts of the world, including Nigeria, with dire consequences for health, economics and the environment, especially in marginalised communities. Abbas disclosed alarming statistics, noting that about 4.2 billion people worldwide live without safe toilets, and approximately 48 million Nigerians still practice open defecation, using the bush and water bodies for waste disposal. This practice extends to many public and private institutions that lack functional sanitary facilities. The consequences of poor excreta and sewage disposal include a high rate of diarrhoea diseases, the second leading cause of morbidity and mortality among children under the age of five. Cholera outbreaks, according to Abbas, are also a manifestation of inadequate toilet facilities. He emphasised that these issues could be mitigated through safe excreta disposal by individuals. The Federal Government of Nigeria, Abbas assured, remained committed to addressing sanitation challenges and ensuring proper excreta management. The FME will continue interventions to control open defecation and promote the provision of safe and adequate toilets across the country, particularly in public places. To strengthen the capacity of environmental health officers, the Ministry has renewed a memorandum of understanding with the Centre for Science and Environment (CSE), India, focusing on technology transfer, technical assistance, capacity building and research development in water, sanitation and environmental management. The CSE has conducted specialised training on affordable toilet designs and feacal sludge management for Environmental Health Officers and Sanitation Desk Officers. Abbas urged stakeholders and commercial entities, including shopping malls, to take measures to ensure everyone has access to toilets in their domains. He solicited support from development partners, NGOs, CSOs, the organised private sector and the public for the sanitation programmes of the Federal Ministry of Environment. In his address, the Minister of Water Resources and Sanitation, Prof. Joseph Utsev highlighted the global significance of the World Toilet Day theme, “Accelerating Change.” He pointed out the poor progress made globally towards meeting the goals of the water, sanitation and hygiene sector under the targets set by SDG6.1 and 6.2. According to the 2023 update report of the WHO/UNICEF joint monitoring programme, an estimated 3.5 billion people worldwide lack access to safe toilets, and over 40% of wastewater is discharged into the environment without treatment. In Nigeria, over 100 million people lack access to basic sanitation, and an estimated 48 million practice open defecation. Utsev stressed that access to adequate water, sanitation and hygiene (WASH) services is crucial for the socio-economic development of any nation, impacting human capital outcomes such as early childhood survival, health and educational attainment. He encouraged everyone to do more to attain the 2025 target date of ending open defecation in Nigeria. Representing the Minister of Works, David Umahi, the director overseeing the permanent secretary of the ministry, Omotayo Olusanya emphasised the contagious impact of poor sanitation on the environment. He reiterated the importance of World Toilet Day in raising awareness and fostering collective responsibility for improved sanitation practices.
