Delhi’s Pollution Crackdown: Over 31,000 Vehicles Fined During GRAP Restrictions In NCR

Old vehicles are among the biggest contributors to Delhi’s air pollution, and during the winter months, restrictions under the Graded Response Action Plan (GRAP) hit these vehicle owners the hardest. The Delhi Pollution Control Committee (DPCC) revealed that over 31,000 challans were issued to vehicles that violated GRAP norms this winter. Every year, as pollution levels rise in Delhi, especially during winter, the government enforces stricter pollution control measures. Under GRAP Stage 3 and 4, BS-III petrol and BS-IV diesel vehicles are not allowed to operate on city roads. These norms are triggered when the Air Quality Index (AQI) crosses 350 and 400, respectively. The DPCC report stated that GRAP was in force for 42 days this winter, 13 days under Stage 3, and 29 days under Stage 4. During this period, officials cracked down on older vehicles, issuing challans to those caught violating the ban. From January to December 2024, over 4.5 lakh vehicles were checked for compliance. Among them were nearly 50,000 trucks that had no business entering Delhi but attempted to pass through. These were turned away at the city’s borders. Environmental expert Anumita Roy Chowdhury from the Centre for Science and Environment (CSE) believes the long-term solution lies not just in vehicle bans but in improving Delhi’s public transport. She noted that if reliable public transport is available, people will naturally reduce the use of private vehicles, which would help cut down pollution more effectively.

Rework The Economics

India should not take action to combat climate change. As I said this to a group of climate change envoys from various European countries, I could notice signs of confusion on their faces. I explained to them my reasons. Development is the most significant challenge that a country like India faces. We know today that this growth should also be inclusive and sustainable. And if we achieve this, we hit a sweet spot—our actions to reduce local pollution and to drive green livelihoods will also reduce greenhouse gas emissions. In this way, our Nationally Determined Contribution (NDC), which puts together the package of actions to reduce emissions, would be based on co-benefits; development, if done right, will also address the urgent crisis of climate change. We know that it is in our interest to achieve this twin goal. We are vulnerable to climate change impacts. But if we do development differently, it would help us avoid the pitfalls of marginalising actions designed solely for climate change. It would help us deepen the public acceptability for taking steps that may not be easy or convenient. I am not sure if I convinced the group of hardened climate negotiators, as their world is narrowly focused on counting greenhouse gases. But let me explain this to you. India, like many other countries, has to ensure growth. This means providing millions with employment, healthcare, education and housing, and increasing energy supply. This has to be our development priority. But development will require taking action that meets the needs of all. So this calls for a change in strategy. We cannot afford a capital and resource-intensive pathway that adds to environmental degradation and inequity in society. We have learnt over the past decades that we cannot adopt the Western countries’ approach to first pollute and then clean up. We just do not have the financial wherewithal to keep repairing the damage. We have to reinvent growth, and this is what many policies in India have done: they have built inclusive sustainability as an outcome of the development policy. This is a unique opportunity for countries like India—not to pit development against climate action but to subsume it within policies designed for growth. For instance, we know we cannot “fix” air pollution without redesigning mobility because personal vehicles, however clean, take up road space and add to pollution and congestion. The Western world has taken the path to subsidise and electrify personal vehicles, which is leading to disruption in industries as they strive to rework supply chains and re-deploy labour for electric cars. We have the opportunity to think of another route—one that reinvents mobility so that we can move people and not cars. This means investing in electric buses and affordable transport like paratransit and two-wheelers. India’s NDC must be about upscaling and integrating low-carbon public transport, and not just counting electric cars. The policy is driven by cleaning up local air but has the added benefit of combating climate change. It is the same with the hard-to-abate industries. We know from experience that our industry will invest in technology that saves costs and increases competitiveness. The cement industry, for instance, switched to using fly ash, not to decarbonise but to use waste as raw material, substitute limestone and reduce the costs of energy. The future of low-carbon industrialisation lies in similar win-win solutions, such as the reuse of waste materials from iron ore slag to biomass to refuse-derived fuel from municipal garbage—all designed to reduce the use of coal and other fossil fuels and to improve efficiency. Most importantly, we must re-engineer the idea and design of a green economy. We cannot afford to mouth platitudes of green employment, knowing fully well that the renewable energy or electric vehicle transition, per se, does not mean more livelihoods. In fact, recent news shows that thousands of jobs have been lost in the UK because of the shift from blast to electric arc furnaces. This is why we see the pushback in Western countries, where much has been said without substance, and this has prompted people, worried as they are about climate change, to care more about livelihoods. India’s opportunity is in the reworking of its economy so that local resources can be used for local livelihoods. If we do this, we can sequester carbon in trees and soil, build resilience in society, withstand extreme weather shocks and also stem migration. We cannot afford an economy that is driven only by the gross domestic product (GDP), which extracts and exports produce, and not by gross nature product (GNP), which invests in natural resources for livelihoods locally. Our plan for climate change is the one that works for people and the Planet. DTE

दिल्ली के वायु प्रदूषण से इन वाहन मालिकों को ज्यादा नुकसान, काटे गए 31 हजार से अधिक चालान

राज्य ब्यूरो, नई दिल्ली। राजधानी में प्रदूषण के कई कारण हो सकते हैं, लेकिन इसका सबसे बड़ा असर पुराने वाहनों पर पड़ रहा है। ग्रेडेड रिस्पांस एक्शन प्लान (ग्रेप) के तीसरे और चौथे चरण के प्रतिबंध लगते ही बीएस तीन मानकों वाले पेट्रोल से चलने वाले वाहन और बीएस चार मानकों वाले डीजल से चलने वाले वाहनों पर रोक लग जाती है। अगर ये सड़कों पर नजर आते हैं तो इनके खिलाफ कार्रवाई की जाती है। आमतौर पर मानसून को छोड़कर, दिल्ली में प्रदूषण का स्तर ज्यादातर दिनों में सामान्य से ज्यादा रहता है। लेकिन, सर्दियों के दौरान स्थिति और भी खराब हो जाती है। इससे निपटने के लिए राष्ट्रीय राजधानी क्षेत्र में प्रदूषण को रोकने के लिए GRAP प्रतिबंध लगाए जाते हैं। AQI के 350 से ऊपर होने पर GRAP 3 प्रतिबंध लगाए जाते हैं और 400 से ऊपर होने पर GRAP 4 प्रतिबंध लगाए जाते हैं। इस दौरान पुराने वाहन मालिकों को काफी परेशानियों का सामना करना पड़ता है। दिल्ली प्रदूषण नियंत्रण समिति (डीपीसीसी) की हाल ही में जारी रिपोर्ट से पता चलता है कि सर्दियों के दौरान जीआरएपी प्रतिबंधों के मद्देनजर कितने वाहनों को निशाना बनाया गया। सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) की कार्यकारी निदेशक अनुमिता रॉय चौधरी का कहना है कि वाहनों पर प्रतिबंध लगाने के बजाय दिल्ली की खराब परिवहन व्यवस्था को सुधारना बेहतर होगा। अगर ऐसा संभव हुआ तो दिल्लीवासी निजी वाहनों का इस्तेमाल वैसे भी कम कर देंगे। डीपीसीसी की रिपोर्ट के मुताबिक सर्दी के मौसम में कुल 42 दिन तक ग्रैप प्रतिबंध लगाए गए। 13 दिन तक ग्रैप 3 प्रतिबंध लगाए गए, जबकि 29 दिन तक ग्रैप 4 प्रतिबंध लगाए गए। इसके चलते पुराने इंजन वाली गाड़ियों को भी प्रतिबंधों का सामना करना पड़ा। इस दौरान कुल 31 हजार 209 वाहनों का चालान किया गया। वर्ष 2024 में जनवरी से दिसंबर के बीच कुल चार लाख 52 हजार 833 वाहनों की जांच की गई। 49 हजार 484 ऐसे मालवाहक वाहन थे, जिनका गंतव्य दिल्ली नहीं था, लेकिन वे यहां से गुजरना चाहते थे। ऐसे वाहनों को बाहर से ही वापस कर दिया गया।

Environmentalists, activists, and opposition slam the AAP government for pro-industry pollution law ahead of Ludhiana bypoll.

The Bhagwant Mann-led Aam Aadmi Party (AAP) government’s decision to adopt the Centre’s Water (Prevention and Control of Pollution) Amendment Act, 2024 in Punjab—allowing industries to discharge pollutants into water bodies in exchange for financial penalties—has ignited a political and environmental firestorm in the agrarian and river-rich state. The controversy revolves around the state’s recent adoption of the amendment, which replaces provisions of the landmark 1974 law. The Punjab Vidhan Sabha passed a resolution last month to adopt the Water (Prevention and Control of Pollution) Amendment Act, 2024, enacted by the Centre. Critics have labelled the amendment a “license to kill,” warning it could irreversibly damage Punjab’s fragile river and groundwater ecosystems. While the original Act included stringent jail terms of up to six years for violators, the amended version replaces criminal penalties with monetary fines ranging from Rs10,000 to Rs 15 lakh. The Punjab Cabinet approved the amended law on February 27, making Punjab the 19th state to adopt it. The move has drawn sharp criticism from environmentalists and opposition leaders, who questioned the need to amend a law that had been in force for 50 years. They accused the AAP-led state government of yielding to industrial and corporate pressure at the cost of Punjab’s water health—especially ahead of the crucial Ludhiana West by-election, where industrial interests are dominant, and AAP faces a litmus test. Jaskirat Singh, a water activist associated with the “Kale Pani Da Morcha”—a movement protesting water contamination in the Buddha Nallah of Ludhiana—called the amendment a “license to kill” Punjab’s rivers. “This government has shown loyalty to the big corporate houses facing action under the previous Act. The timing of this amendment, ahead of the Ludhiana West bypoll, shows the government is under pressure from industrialists,” he said. Jaskirat, who is leading protests against the amendment in Ludhiana, also accused the AAP government of failing to implement the earlier Act, which mandated strict punishments. “There are around 50 big industrialists accused of violating Section 33A of the Water Act, 1974. This amendment will allow them to escape by paying penalties,” he added. Another activist, Colonel Jasjit Singh Gill (Retd), warned the new law would allow industries to pollute with impunity. “March 28 will be marked as a black day for making Punjab waters black permanently. Shame on such lawmakers who sacrificed Punjab’s right to reject black laws,” he said. While the Act was enacted by the Centre and left optional for states to adopt, environmentalists argue that it is ill-suited for Punjab’s water resources and agriculture. AAP’s Rajya Sabha MP and prominent water activist Balbir Singh Seechewal—who had previously been a vocal critic of the state’s failure to enforce the 1974 Water Act—faced criticism for remaining silent on the issue. However, in the Rajya Sabha, Seechewal expressed dismay, calling the amendment “pro-industry” and emphasised the need to strengthen the original Act and reinstate punitive provisions. He urged the government to at least impose the highest penalties consistently to deter violators. The state government has yet to issue an official response to the backlash. However, when the cabinet approved the amendment on February 27, it defended the move by highlighting that Punjab became the 19th state to adopt the Centre’s law, which is already in force in Himachal Pradesh, Rajasthan and Union Territories. One of the most contentious aspects of the amended law is the shift in control from the state to the Centre. Under the new provisions, the Centre will appoint adjudicating officers to impose penalties, and appeals will go to the National Green Tribunal, with 10% of the penalty amount to be deposited in advance. This shift has raised concerns about the erosion of federal powers, as the state’s role in nominating the chairperson of the State Pollution Control Board has also been removed. Environmental experts say the timing of the amendment couldn’t be worse. The State of the Environment Report 2023, released by the Centre for Science and Environment (CSE) and Down to Earth, revealed that 46% of India’s rivers are already contaminated. Punjab has faced severe criticism over river water pollution and remains under NGT scrutiny due to its failing sewage treatment systems and deteriorating groundwater quality. Social activist and advocate Kamal Anand criticised AAP, stating, “They won the last election on the promise of saving Punjab’s rivers. Now, they’re following the same path as previous governments. Adopting this amendment shows the AAP government has no real concern for Punjab’s water or the health of its people.” Passed by Parliament in February last year, the Water (Prevention and Control of Pollution) Amendment Bill, 2024, amends the original Water (Prevention and Control of Pollution) Act, 1974. The Act establishes the Central and State Pollution Control Boards (CPCB and SPCBs) to prevent and control water pollution. The amendment decriminalises several violations, replacing criminal penalties with monetary fines. Initially, the amended law was implemented in Himachal Pradesh, Rajasthan, and the Union Territories, while other states were given the option to adopt it by passing resolutions.

Overshadowed by Waste: Living Adjacent to Delhi's Okhla Landfill

It has been more than a year now since then chief minister of Delhi Arvind Kejriwal and Lieutenant Governor of Delhi V.K. Saxena inaugurated a sanitary, engineered landfill in Tehkhand Okhla on March 12, 2024. In a social media post announcing the inauguration, Kejriwal called it “a significant step towards sustainable waste management and environmental conservation”. The engineered landfill is now operational and running. While the lives of those living near the landfill have improved slightly, their living conditions still leave much to be desired. The efficacy of the engineered landfill also remains unknown. There are three main landfill sites in Delhi: Ghazipur, Okhla and Bhalswa. As per a press release issued by the Delhi Pollution Control Committee (DPCC), it has not authorised any of these three sites. However, municipal bodies have informed the DPCC that they have no option but to use these sites to dispose of municipal solid waste, as land is unavailable in Delhi. They also claim that a request has been made to the Delhi Development Authority (DDA) to allot land for landfill sites, but to no avail. The South Delhi Municipal Corporation and North Delhi Municipal Corporation have stated that these landfill sites are being continued at the risk of human life. Additionally, Delhi also has three Waste to Energy (WtE) plants: Timarpur-Okhla WtE plant, Ghazipur WtE plant and Narela WtE plant. However, an investigative report by The New York Times cites the WtE plants as a cause of several pollutants. The locals in Okhla and Bawana have previously protested the opening of these plants but to no avail. The engineered landfill has come up as a poignant solution to the problem of ash generated upon processing in a WtE plant. A landfill is a carefully constructed site wherein inert, unprocessable waste is discarded. However, the three ‘landfill sites’ in Delhi operate as unmethodical sites where all municipal solid waste is dumped. In a video posted by the Aam Aadmi party, Durgesh Pathak, the former incharge of MCD has explained the working of the engineered landfill, which offers systemic treatment of waste, in a way that minimises environmental impact. The engineered site has a five-layer membrane, which prevents the contamination of land. The ash generated from WtE plants is dumped at the site, and pressed. The ash is then covered with a layer of dirt and soil. Further, the engineered site has pipes which collect contaminated rainwater and transfer it to a ‘leachate treatment plant’. This prevents groundwater from being contaminated. Once the engineered landfill is at capacity, Pathak claims, the site will be suitable for use, as a recreational park or a land for further development. Kalaam is a 32-year-old migrant worker from Bihar. He owns a tyre repair shop and sits right outside the Okhla landfill. He claims to have watched the landfill transform from a dense jungle to a cement factory and then to the garbage dump it has now become. He affirms the positive effects of the engineered landfill and WtE plants built close to the landfill. “As far as I can tell, the garbage dump has become smaller, even though the trucks seem to be bringing in more waste. I hear that the plant processes the waste into electricity. There used to be a lot of smoke earlier, but that has also decreased since the new (engineered landfill) development.” Kalaam is hopeful but says he fears for the residents of VP Singh Camp, the actual stakeholders of the landfill’s toxins. VP Singh Camp, named after former prime minister Vishwanath Pratap Singh, is a resettlement colony in Tughlakabad, Delhi. According to the Delhi Shelter Board website, VP Singh Camp is registered as a Jhugi-Jhopdi Cluster (JJC) in Ward 197 of South Delhi. It has over 1,709 households, across an area of 38,500 square metres. The lanes are narrow, and the place has a strong stench due to its proximity to the Okhla landfill. Rajnish Singh Das, a 50-year-old man who works as a priest at a mandir on the outskirts of the JJC, claims to have watched the landfill become its present size. “It grows bigger every year. All parties reassure us that they will clear out the area, but to no effect.” He speaks of the foul odour that plagues the area, “The stink is persistent in this area, but we have gotten accustomed to it. It is especially terrible during the monsoon because the rain causes the waste to roll onto the roads. Dark, visibly contaminated water gets logged on the roads, and the entire place reeks terribly.” Talking about the engineered landfill and the WtE plant, he says, “Earlier, a lot of ash and fumes used to rise from the plant, but that has decreased in the past year. It might not be much, but at least there is less solid ash now.” Water crisis The primary problem faced by the residents of the VP Singh camp is the dearth of clean water. The groundwater is pale yellow and has a distinct smell. Bindu, Rajnish Das’s wife, tells The Wire, “The water here is not drinkable. We only use it for cleaning and washing. But washing clothes with this water leads to them losing their colour and turning yellow.” With no clean water supply and no means to purify the contaminated water, most residents of the area resort to buying bottled water for consumption. “Everything you consider pleasant weather only results in hardships for us. As the wind blows, so does dirt and light waste from the landfill, such as poly bags. When the rain falls, so does the garbage,” says Shyam Yadav, the owner of a dhaba on the outskirts of the colony. He talks about buying bottled water to cook the food served at the dhaba. “The water quality here is so bad, even animals wouldn’t want to consume it – it is unappealing to look at, smell and taste. It cannot be used even to rinse vegetables. I spend about Rs 100-200 on water bottles each day.” Yadav alleges that the groundwater does not even allow for detergents to lather. “Sometimes we use bottled water to let soap lather and then rinse with the groundwater.” “The pale yellow colour of the water is possibly due to the landfill leachate seeping into the groundwater,” explains Bhawana Tanwar, the executive director of There is No Earth B, an NGO working towards climate action. Soluble components from the waste dissolve into the rainwater that falls onto the landfill. This contaminated water, called ‘liquid leachate’, causes groundwater to become contaminated. “The usability of the water can only be understood upon studying the microbacterial contaminants, dissolved metals, dissolved oxygen pH value and other impurities present in the water.” Lack of sanitary washrooms To further exacerbate the perils of the colony, there are only two community toilet complexes in the area. As per the data on the Delhi Shelter Board website, the region only has one toilet complex, the status of which is given as “repair required”. Nandini (11) is one of the many young children growing up in the shadows of the towering landfill. “My house does not have a washroom, so we rely on the community toilets, which also close by 11 pm. I avoid going to the washroom too late, but if there’s no other choice, I go to the mountain (landfill).” Several people confessed to open defecation, either near the landfill site or in the jungles surrounding the area. “We walk long distances just to use the washroom. It is scary to do so after sunset because many local men are often under the influence by then. It is common to be harassed,” says Vineeta, a resident. “Some people have built personal washrooms in their houses now, but most of us rely on the community toilets,” says Mintra Thakur, a 35-year-old woman who lives in a rented single-room house in the colony. “If we need to go at night, we either ask the neighbours or find other means,” says the single mother. Mintra says that the children in the colony frequently fall ill, owing to the subpar living conditions. Health impact “A large majority of my family income goes into hospital bills. You can hear it in my voice: the allergens due to the landfill have led me to have persistent coughs and a sore throat,” says Kamlesh, a woman in her mid-50s. She talks about how residents cover their faces while walking, but one can only mask up for so many hours. “Using this water to bathe also causes our hair to become dry and rough.” Dr S.K. Shaha is an Ayurvedic medicine doctor who has a clinic in the camp. He talks about the common ailments in the area: “I often get patients with persistent coughs and difficulty breathing. Bathing with the contaminated groundwater also leads to several common skin ailments, such as eczema.” He also talks about infectious diseases caused due to poor living conditions: “The waste attracts houseflies, which are known vectors of diseases. Hygiene is a luxury the locals don’t have.” Multiple studies cited by the National Institute of Health (NIH) have shown that people living close to landfills have a greater chance of facing illnesses such as asthma, cuts, diarrhoea, stomach pain, recurring flu, cholera, malaria, cough, skin irritation, diarrhoea and tuberculosis. Unsegregated waste Tribhuvan Singh Bisht, deputy programme manager at the Centre for Science and Environment, a research organisation based in New Delhi, explains that the ‘landfills’ in Delhi are garbage dumps. The ‘sanitary landfill’ can be better explained as a ‘monofill’. “Landfills are regulated areas specifically designed to manage waste safely to minimise environmental impact. Most ‘landfills’ in India are unregulated garbage dumps where all organic and inorganic waste is indiscriminately dumped.” Tanwar adds, “Separating the organic and biodegradable waste from the non-biodegradable waste at the source lets us treat it in a scientific matter. Going back to practices such as composting to treat organic waste can be a key step in minimising environmental pollution.” Bisht explains that the WtE plants are supposed to only treat matter which has no way of decomposing by itself – plastics. “In an ideal scenario, only plastic waste would be burnt in WtE plants. This would increase the efficacy in generating electricity and decrease the environmental pollutants. However, the lack of segregation makes this impossible.” While the MCD waste collection truck does have separate compartments for organic and inorganic waste, it has been observed that citizens continue to dump unsegregated waste. Speaking of the engineered landfill or monofill, Bisht explains that the purpose of the project is not to treat the waste, but the ash generated when the waste is processed in WtE plants. “Burning of waste in WtE plants leads to the generation of fly ash. This fly ash contaminates the air, and when the solid matter is disposed of in a garbage dump, it seeps into the groundwater. This is where the monofill plays a key role by offering a space for the ash to be dumped properly. The engineered landfill has a geotextile membrane which prevents the ash from coming in contact with the groundwater.” Bisht maintains that the efficacy of the ‘sanitary landfill’ is a question which would remain unanswered. The Wire reached out to the MCD to ask about living conditions around the sanitary landfill and its efficacy. The article will be updated if a response is received.

Delhi’s Ozone Levels Spike Sharply In Many Areas, Raising Alarms Over Public Health

Ozone pollution has surged to alarming levels in several parts of the capital, reaching nearly twice the permissible limit. According to SAFAR, a monitoring agency under the Ministry of Earth Sciences, ozone concentration near the Major Dhyan Chand National Stadium hit 239 micrograms per cubic meter on Tuesday. As per national air quality standards, this level should not exceed 100 micrograms per cubic meter. Scientists note that while ozone spikes were previously confined to the summer months, the trend has now become a year-round concern in many parts of the country. Elevated ozone levels can damage the lungs and significantly increase the risk of heart disease, making it a growing public health threat. Unlike other pollutants, ozone doesn’t have a single direct source. Instead, during extreme heat, emissions from vehicles and power plants react in the atmosphere to form ozone, leading to a rise in its levels. According to a report by the Centre for Science and Environment (CSE), many Indian cities have witnessed a worrying increase in ozone pollution. This summer, ten major cities recorded dangerously high ozone levels, with Delhi being the most affected. The report, titled “An Invisible Threat: Air Quality Tracker”, analyzed ozone trends in Delhi-NCR, Bengaluru, Mumbai, Chennai, Kolkata, Pune, Greater Ahmedabad, Greater Hyderabad, Greater Jaipur, and Greater Lucknow. The findings revealed that ozone levels rose more sharply between January and March compared to the summer months of April to July. Ahmedabad reported an astonishing 4000-fold increase in ozone levels compared to last year, while Pune saw a 500 per cent rise and Jaipur recorded a 152 per cent jump.

Troubling Ubiquity

Plastic, a versatile material with a lifespan of hundreds of years, has multiple benefits and uses. However, its production, consumption, and disposal have severe environmental consequences, including water pollution, marine life deaths, and a significant carbon footprint due to fossil fuel dependence. According to European Environment Agency (EEA), the average annual plastic consumption in Western Europe is approximately 150 kg per person, exceeding the global average of 60 kg by more than twofold. According to a recent report, the United States generates the most plastic waste per capita worldwide, with an average American producing 130.09 kg annually. In contrast, India’s per capita plastic waste generation stands at around 19.88 kg. As a relatively recent invention, plastic’s affordability and adaptability have made it ubiquitous in modern times. However, its lifecycle poses significant challenges. Alarmingly, only about 9 per cent of all plastic ever produced has been recycled, while 12 per cent has been incinerated. The remainder remains in use or has been disposed of in landfills or released into the environment, including oceans, as per EEA. In March 2022, the fifth session of the UN Environment Assembly adopted a landmark resolution to develop an internationally legally binding instrument addressing plastic pollution, including in marine environments. The resolution tasked the UNEP Executive Director with convening an INC to craft the instrument, adopting a comprehensive approach that encompasses the entire life cycle of plastic, from production and design to disposal. A growing tide of plastic waste is threatening the Ruzizi dam in eastern Congo, leading to frequent power outages in several major cities. Local authorities are scrambling to address the issue, which highlights the devastating environmental consequences of plastic pollution. The environmental impacts of discarded plastics, littering, leaching of toxic components and the contamination of ecosystems and the food chain with micro plastics, are well established. Even after centuries, plastic waste remains, refusing to decompose. Its persistence harms marine life and ecosystems. The toxic chemicals leach into water sources and there are several human health risks from micro plastic consumption. The plastic waste disintegrates into microscopic pieces, contaminating the food chain and endangering humans and animals. Oceans and landscapes are congested with plastic, from the deepest sea beds to the highest mountains. Emissions from production, use, and disposal degrade the environment, accelerating climate change. Despite mounting evidence, plastic production is expected to rise, intensifying the crisis. Urgent action is necessary to mitigate the effects of plastic pollution. Consensus on plastic pollution remains elusive, mirroring challenges in climate talks, due to economic, job, and development concerns. The High Ambition Coalition advocates drastic measures, including a 40 per cent production cut by 2040 and lifecycle interventions. In contrast, oil and petrochemical lobbies resist reductions, promoting recycling and waste management instead. Plastics, primarily made from fossil fuels like petroleum, natural gas, and coal, are at the centre of this debate. The Global Coalition for Plastic Sustainability, an alliance of plastic-producing countries, pushes for a waste management-focused approach. According to a Centre for Science and Environment (CSE) report, Iran’s announcement of Global Coalition for Plastic Sustainability faced opposition at the INC’s third session. The coalition’s status was downgraded to a “like-minded group”. However, Iran’s interventions on behalf of this group garnered support from Russia, India, Cuba, and Western Asian nations, including Saudi Arabia, Bahrain, and Iraq. This coalition advocates for a legally binding instrument prioritising waste management to minimise the impact on plastic-producing countries. India, adhering to the principle of Common but Differentiated Responsibilities (CBDR) on climate issues, emphasises that any legally binding instrument should consider individual countries’ circumstances. Indian officials assert that solutions to pollution should not involve binding targets or production caps.

1.7crUnresolvedOffences Against Pvt VehiclesOutpace Commercial Wheels

New Delhi: While Delhi Trac Police trac-police) is considering ways to tackle the backlog of trac violations by commercial vehicles, private car owners, considered more law-abiding than their commercial counterparts, are ratcheting up a more worrying number of oences. Around 9.3 lakh private vehicles in the city have three or more challans pending against their name for road rule violations. The total bookings awaiting resolution among private vehicles is 1.7 crore, far exceeding the 16 lakh challans pending against commercial vehicles. The top three private vehicles in this dishonour list are yet to pay 601, 509, and 464 challans. Among vehicles with unsettled nes, there are 51.6 challans for speeding beyond permitted limit. The second highest oence is improper parking with 21.5 lakh violations. There are 21 lakh challans pending payment for violations related to riding without a helmet on a two-wheeler. Interestingly, an ongoing study by CSIR-Central Road Research Institute, based on observations of 2,34,740 two-wheeler riders and passengers on dierent road types and urban environments, found that while a signicant proportion of riders wear helmets, only 63% did so correctly. Not holding a valid pollution under control certicate has emerged as the h most common oence, with over 12.9 lakh unresolved oences. Ocials attribute this to increased surveillance and digital enforcement mechanisms that ag expired or missing PUC certicates in real time. How will this huge pendency in bookings be resolved? Experts say a balanced approach is needed — fair to motorists, rule violators and police — else the people will continue violating rules. S Velmurugan, chief scientist and head, Trac Engineering and Safety Division, CSIR-CRRI, said, "From overspeeding to the pollution violations, the pendency on resolving bookings has risen, but private car owners remain indierent. Many wait to pay their nes during the special Lok Adalat camps when the amounts are reduced. Some don't even bother doing that. Without more manpower for impounding end-of-life vehicles and trac ocers being given seizure powers, enforcement will remain weak. We need a cap — say, three challans — beyond which vehicles can be impounded." Vivek Chattopadhyay, principal programme manager (Clean Air and Sustainable Mobility), Centre for Science and Environment, said, "Trac certainly has overwhelmed the city. Building more yovers or underpasses hasn't helped. Central govt thought that increasing penalties for oences would intimidate people into obeying the rules. But today there is almost lawlessness on the roads. Unless we invest in public transport, regulate private vehicle use and redesign roads for people instead of cars, the congestion and pollution will only get worse."

Kochi’s air quality ‘poor’ mostly this year, pollutant levels a worry

Kochi: The air quality index (AQI) of Kochi was more than 100 — which is considered ‘poor' — on most days in the last three months of 2025, according to the index recorded by various monitoring agencies. AQI was more than 100 for 10 days in Jan, 24 days in Feb and 20 days in March. In addition to this, pollutant levels also remain a concern. Experts said that in the last five years, they noticed a trend where AQI levels in the city peak during the months from Jan to April as construction activity increases to finish works before monsoon. Added to this is high atmospheric particulate matter (PM) due to vehicular emissions and road and infrastructure construction activities. Even in the evenings, when the city experienced slight rainfall, AQI ranged between 80 and 85. A recent study by Cusat's atmospheric science department, presented last month at CARE 2025 climate conference, further examined the trend between 2018 and 2023. It was found that the highest level of pollution was observed on Tuesday and Friday — especially during rush hours in the morning and evening — while it was lower on weekends. The morning AQI peaks are influenced by local meteorological conditions and household emissions or burning waste. AQI is lowest at night throughout the year, with even Kochi's noon hours being better with a below-50 AQI. "It's necessary to take proactive and preventive action now as Kochi and the surrounding areas are being urbanised and motorised rapidly and can worsen the air quality trends if the growing sources of pollution like vehicles, construction and waste, among others, are not addressed immediately," said Centre for Science and Environment (Delhi) air pollution and clean transportation programme head Anumita Roychowdhury. Yet, experts said AQI in Kochi is much better than in many other cities in India as the city has an advantage as it is the entry point of the southwest monsoon and changing weather works in its favour and acts as a cleanser. "Due to its geographical and climatic advantages, pollution concentration does not build up here," said Roychowdhury. However, this change in AQI levels has city pulmonologists worried. They said "air pollution is impacting a productive population's quality of life" with an increase in children and young adults reporting complaints of respiratory ailments and allergies. "We are seeing a rise in young asthmatics due to allergies and we have to regularly increase the medicine dosage. Standing even for 10 minutes at a bus stop often causes suffocation due to increased pollution, making the young and middle-aged vulnerable to conditions like chronic lung disease or COPD," said Dr Paramez AR, senior pulmonologist and member of Cochin Thoracic Society, which spreads awareness on the impact of air pollution on health. Kochi: The air quality index (AQI) of Kochi was more than 100 — which is considered ‘poor' — on most days in the last three months of 2025, according to the index recorded by various monitoring agencies. AQI was more than 100 for 10 days in Jan, 24 days in Feb and 20 days in March. In addition to this, pollutant levels also remain a concern. Experts said that in the last five years, they noticed a trend where AQI levels in the city peak during the months from Jan to April as construction activity increases to finish works before monsoon. Added to this is high atmospheric particulate matter (PM) due to vehicular emissions and road and infrastructure construction activities. Even in the evenings, when the city experienced slight rainfall, AQI ranged between 80 and 85. A recent study by Cusat's atmospheric science department, presented last month at CARE 2025 climate conference, further examined the trend between 2018 and 2023. It was found that the highest level of pollution was observed on Tuesday and Friday — especially during rush hours in the morning and evening — while it was lower on weekends. The morning AQI peaks are influenced by local meteorological conditions and household emissions or burning waste. AQI is lowest at night throughout the year, with even Kochi's noon hours being better with a below-50 AQI. "It's necessary to take proactive and preventive action now as Kochi and the surrounding areas are being urbanised and motorised rapidly and can worsen the air quality trends if the growing sources of pollution like vehicles, construction and waste, among others, are not addressed immediately," said Centre for Science and Environment (Delhi) air pollution and clean transportation programme head Anumita Roychowdhury. Yet, experts said AQI in Kochi is much better than in many other cities in India as the city has an advantage as it is the entry point of the southwest monsoon and changing weather works in its favour and acts as a cleanser. "Due to its geographical and climatic advantages, pollution concentration does not build up here," said Roychowdhury. However, this change in AQI levels has city pulmonologists worried. They said "air pollution is impacting a productive population's quality of life" with an increase in children and young adults reporting complaints of respiratory ailments and allergies. "We are seeing a rise in young asthmatics due to allergies and we have to regularly increase the medicine dosage. Standing even for 10 minutes at a bus stop often causes suffocation due to increased pollution, making the young and middle-aged vulnerable to conditions like chronic lung disease or COPD," said Dr Paramez AR, senior pulmonologist and member of Cochin Thoracic Society, which spreads awareness on the impact of air pollution on health.

India should reject full FTA with US, opt for zero-to-zero tariff deal instead: GTRI

As former US President Donald Trump announced a 90-day pause on tariffs to allow trade negotiations, a new report by the Global Trade Research Initiative (GTRI) has advised India to steer clear of signing a full Free Trade Agreement (FTA) with the United States. Instead, GTRI has recommended that India pursue a limited “Zero-for-Zero” tariff deal—covering 90% of industrial goods—to protect its strategic interests and vulnerable sectors. According to the GTRI, a comprehensive India-US FTA could prove costlier than beneficial, as it may force India into damaging trade-offs. The report warns that Washington’s likely demands could compromise India’s economic, agricultural, and digital sovereignty. Key concerns include: Undermining the Minimum Support Price (MSP) system for farmers Allowing genetically modified (GM) food imports Lowering agricultural tariffs, impacting millions of Indian farmers Changing patent laws to extend US pharmaceutical monopolies Permitting direct entry of US e-commerce giants into India’s consumer market Such changes, GTRI said, would endanger farmer incomes, threaten food security and biodiversity, affect public health, and harm small retailers. Reducing farm tariffs could impact the livelihoods of hundreds of millions of Indians. Similarly, cutting duties on automobiles could damage India’s auto industry, which contributes nearly one-third to the country’s manufacturing output. Warning from history: Australia’s car industry collapse The report cites the collapse of Australia’s domestic car industry in the 1990s as a cautionary example. Australia had slashed tariffs under pressure, which eventually led to de-industrialisation in the auto sector. India’s auto industry, which contributes nearly one-third of its manufacturing GDP, could face a similar fate if duties on imported vehicles are reduced under an FTA with the US. Agriculture, pharma & retail sectors at risk Reducing farm tariffs, the report warns, could jeopardise the livelihoods of over 100 million Indians dependent on agriculture. Similarly, changes to India’s patent regime may restrict access to affordable medicines, undermining public health initiatives. Further, letting US e-commerce companies operate without restrictions could devastate India’s small retail businesses, many of which are yet to fully recover from the pandemic. Zero-to-Zero tariff deal: A smarter alternative Instead of a full-blown FTA, GTRI advocates for a “Zero-for-Zero” industrial tariff deal, similar to the model Europe has offered the United States. This type of deal: Focuses only on industrial goods Avoids complex negotiations on agriculture, pharma, and digital services Reduces risk for India’s vulnerable sectors while boosting trade in manufacturing Such a limited, strategic trade deal could help India grow its industrial exports without compromising domestic priorities. Better FTA options: EU, UK, Canada, Japan GTRI further suggests that India focus its trade diplomacy on partners where the risks are lower and complementarities are higher, such as: European Union, United Kingdom, Canada, Japan, South Korea, and ASEAN countries. The think tank also encourages re-engaging with China and Russia, and exploring joint value chains in chemicals, machinery, and electronics, where both economies could benefit from sourcing and exporting together. Trade analysts have praised GTRI’s cautionary stance. Speaking on the matter, Ajay Srivastava, founder of GTRI, emphasised: “India must not bargain away its core interests. The focus should be on smart, limited agreements—not one-sided FTAs that damage agriculture, pharma, or small business.” Dr. Sunita Narain, policy expert and director of a leading think tank, added: “Food security, public health, and digital sovereignty are non-negotiables. The idea of zero-for-zero deals makes sense because they keep us in control of our economic narrative.” While a US-India trade deal sounds attractive on paper, GTRI’s report urges policymakers to tread with caution. A targeted zero-to-zero tariff agreement, rather than a full-scale FTA, may be the best path forward for India in 2025. As global trade dynamics shift rapidly, India’s challenge lies in balancing access with autonomy—ensuring that growth doesn’t come at the cost of national interest.

भीषण गर्मी से रातें भी होने लगीं गर्म, दिल्लीवासियों ने किया तीन वर्षों में सबसे ज्यादा तापमान का अनुभव

राजधानी भीषण गर्मी की चपेट में है और न दिन में चैन है और न रात को चैन। हर कोई गर्मी और लू से बेहाल है। हालात ऐसे हो गए हैं कि दिन ही नहीं, रातें भी गर्म होने लगी हैं। इसका अंदाजा इसी बात से लगाया जा सकता है कि मंगलवार रात का तापमान भी तीन साल में अप्रैल में सबसे ज्यादा रहा। दिल्लीवासियों ने अप्रैल में इस सीजन की पहली गर्म रात पांच इलाकों में झेली। हालांकि, मौसम विभाग ने पश्चिमी विक्षोभ के असर से गुरुवार से मौसम में बदलाव और तापमान में कमी आने का अनुमान जताया है। मौसम विभाग के अनुसार गुरुवार को आमतौर पर आसमान में बादल छाए रहेंगे। बूंदाबांदी या हल्की बारिश हो सकती है।बादलों की गड़गड़ाहट, बिजली चमकने और 30 से 40 किलोमीटर प्रति घंटे की रफ्तार से हवा चलने का पूर्वानुमान है। हवा की गति 50 किलोमीटर प्रति घंटे तक भी जा सकती है। अधिकतम और न्यूनतम तापमान क्रमश: 39 और 25 डिग्री रह सकता है। कमोबेश यही स्थिति शुक्रवार को भी रहेगी। मौसम विभाग ने इन दो दिनों के लिए येलो अलर्ट भी जारी किया है, लेकिन लू चलने का नहीं बल्कि तेज हवाओं के साथ हल्की बारिश का। बुधवार को दिल्ली का तापमान बुधवार को दिल्ली का न्यूनतम तापमान सामान्य से 5.6 डिग्री अधिक 25.6 डिग्री दर्ज किया गया। यह 2022 के बाद तीन साल में अप्रैल में सबसे अधिक न्यूनतम तापमान है। पीतमपुरा में यह 29.5 डिग्री सेल्सियस पर पहुंच गया। अधिकतम तापमान सामान्य से 5.4 डिग्री अधिक 40.5 डिग्री सेल्सियस दर्ज किया गया। यह पिछले दिन से आधा डिग्री कम है। आयानगर में यह सबसे अधिक 40.9 डिग्री रहा। हवा में नमी का स्तर 73 में से 31 दर्ज किया गया। मौसम में बदलाव चिंताजनक गौरतलब है कि अलवर में सेंटर फॉर साइंस एंड एनवायरमेंट (सीएसई) की ओर से हाल ही में आयोजित तीन दिवसीय पर्यावरण सम्मेलन में विशेषज्ञों ने मौसम में आ रहे इस बदलाव पर चिंता जताई थी। मौसम एवं जलवायु वैज्ञानिकों ने बताया कि शहरों में बढ़ती आबादी, कंक्रीट के जंगलों का विस्तार और घटते वन क्षेत्र रातों के गर्म होने के लिए जिम्मेदार हैं। ऊंची इमारतों के बीच फंसने के कारण जमीन से पैदा होने वाली गर्मी रात में भी ऊपर नहीं आ पाती। ऊपर से एयर कंडीशनर की गर्मी भी रातों को और गर्म बना रही है। अगले पांच दिन तक लू नहीं चलेगी उधर, लगातार तीन दिन तक भीषण गर्मी और लू चलने के बाद मौसम विभाग ने पूर्वानुमान जताया है कि गुरुवार से अगले पांच दिन तक लू नहीं चलेगी। इसके साथ ही पश्चिमी विक्षोभ के कारण मौसम में बदलाव और तापमान में गिरावट के भी आसार हैं।

Air pollution level improved in 77 cities since 2017, shows study

Under the National Clean Air Programme, air pollution levels improved in 77 cities but increased in 23 others, a new analysis has found. Compared to baseline year of 2017-18, PM10 (coarse pollution particles; with a diameter of 10 micron) levels increased in 23 cities, remained unchanged in two and improved in 77 cities, an analysis by Centre for Research on Energy and Clean Air (CREA) has found. It also found that out of 130 cities under the National Clean Air Programme (NCAP), 28 still do not have Continuous Ambient Air Quality Monitoring Stations (CAAQMS), indicating critical gaps in real-time air quality monitoring infrastructure. PM10 data from the remaining 102 cities with CAAQMS was analysed for the period April 1, 2024 to March 31, 2025 (FY 24-25) by the CREA team. Delhi recorded the highest annual (FY 24-25) PM10 concentration at 206 micrograms per cubic metres among NCAP cities, followed by Byrnihat (in Meghalaya) at 200 micrograms per cubic metres, and Patna at 180 micrograms per cubic metres--each over three times higher than the national standard of 60 micrograms per cubic metres, the analysis added. Compared to the previous year (FY 23-24), PM10 levels decreased in 69 NCAP cities while 33 saw an increase. Since 2017-18, 10 cities in Uttar Pradesh recorded an over 40% reduction in PM10 levels compared to the baseline year, followed by two cities each in Uttarakhand and Punjab. One city each from Tamil Nadu, Jharkhand, Jammu & Kashmir, Rajasthan, Nagaland, Maharashtra, and West Bengal also achieved an over 40% reduction. Odisha and Maharashtra had the highest number of cities with increased PM10 levels. Assam reported four such cities, Madhya Pradesh , three, and Bihar, West Bengal, and Chhattisgarh , two cities each. “A few Indian cities have shown notable improvement in reducing PM 10 levels, but the majority remain far from meeting the NCAP targets, and with just one year to the deadline. Despite some progress, 91 of the 102 NCAP cities with CAAQMS data still continued to exceed the lenient national annual PM10 standard during FY 2024–25,” said Manoj Kumar, Analyst at CREA. ‘In recent years, NCAP assessments have typically used integrated data from Continuous Ambient Air Quality Monitoring Stations (CAAQMS) and National Air Quality Monitoring Programme (NAMP) networks by averaging values from both systems to evaluate air quality trends. However, this approach risks misrepresenting PM10 levels, as the two systems vary significantly in measurement technique and frequency. To ensure accuracy and avoid underestimation or overestimation, it is important to assess trends using CAAQMS and NAMP data separately,” he added. The union environment ministry launched National Clean Air Programme (NCAP) in January, 2019 with an aim to improve air quality in 131 cities in 24 States/UTs by engaging all stakeholders. The programme envisages reductions up to 40% or achievement of National Ambient Air Quality Standards for PM 10 concentrations by 2025-26. Road dust mitigation has been the primary focus of the NCAP with much lower funding for combustion sources that emit pollutants, a Centre for Science and Environment (CSE) assessment said last year. Of the money spent, 64% ( ₹10,566 crore) has gone into road paving, widening, pothole repair, water sprinkling, mechanical sweepers, etc. Only 14.51% has been used for controlling biomass burning, 12.63% for reducing vehicular pollution and a mere 0.61% for controlling industrial pollution. NCAP was originally planned to tackle both PM10 and PM2.5 concentrations in the 131 non-attainment cities or cities that consistently fail to meet the standard. In practice, only PM10 concentration has been considered for performance assessment. PM2.5, the more harmful pollutant , emitted largely from combustion sources, has been neglected, CSE found.

Gurgaon 7th, Charkhi Dadri 8th in list of cities with worst air quality this March

Charkhi Dadri and Gurgaon from Haryana, for a 12th month in a row, made it to the list of 10 Indian cities with highest air pollution. Pollution data analysed by the Centre for Research on Energy and Clean Air (CREA) this March ranked Gurgaon on the 7th spot, with average particulate matter 2.5 (PM2.5) calculated at 81µg/m³. It was followed by Charkhi Dadri, with average PM2.5 level at 80 µg/m³, in the 8th position. CREA, which studied air pollution data from 142 cities across the country, found that Meghalaya's Byrnihat (160 µg/m³) was the most polluted. Ghaziabad (112 µg/m³) in UP came second, and the others on the list were Hajipur (Bihar), Angul (Odisha), Nalbari (Assam), Guwahati (Assam, Nayagarh (Odisha) and Sasaram (Bihar). PM2.5 levels in these cities consistently breached safe limits of 60µg/m³ set by the Central Pollution Control Board (CPCB) and 15 µg/m³ by the World Health Organization. Experts pointed out that Gurgaon and Charkhi Dadri have been listed among India's most polluted cities in monthly analysis since the past year. "The repeated presence of Haryana's cities among the top 10 most polluted in India is a clear sign that current measures are falling short. Without immediate and sustained intervention, air pollution in the state remains a public health concern," said Manoj Kumar, an analyst at CREA. PM2.5 — tiny airborne particles that can penetrate into the lungs — are cause and worsen respiratory issues and cardiovascular diseases. High exposure, even for a month, can pose serious risks to vulnerable populations, including children and the elderly. "Gurgaon, one of India's major cities, has seen a sharp rise in air pollution level that is paralleled by a growing number of respiratory disorders among residents. Pollutants can irritate every mucous membrane, making any pre-existing respiratory diseases worse, such as asthma, bronchitis and COPD (chronic obstructive pulmonary disease). Long exposure to polluted air can trigger serious health implications such as heart diseases and strokes," said Dr Kuldeep Kumar Grover, head of critical care and pulmonology at CK Birla Hospital, Gurgaon. CREA's report also included comparative analysis of PM2.5 levels recorded in March 2024. Then too, Gurgaon and Charkhi Dadri made it to the top 10 most polluted cities list, though their rankings were worse, at the 5th and 7th spots, respectively. Gurgaon's PM2.5 concentration was the same at 81 µg/m³, and Charkhi Dadri – at 64 µg/m³ — was relatively lower than March 2025. Shubhansh Tiwari, a research associate at the Centre for Science and Environment (CSE), said states need to make a concerted effort to reduce air pollution in cities across the country. "Stricter enforcement of emission standards, promotion of clean technologies and public awareness campaigns are crucial to combat this menace. Though some cities have witnessed a reduction (in PM2.5 levels), it is very minimal," he said. Asked about the CREA's findings, officials of Haryana State Pollution Control Board (HSPCB) said on Tuesday that Gurgaon's air quality has improved compared to last year. "There has been a reduction in pollutants, but it is true that the ground reality has not changed completely. Coal-based industries have been shifted out of NCR cities, and many have converted to PNG. Road infrastructure has also improved in the last four years, and awareness about pollution has also increased. But we still have miles to go. We are working towards achieving clean air," said Vijay Chaudhary, regional officer, Gurgaon (south). Ajay Thakur, a resident of Sector 30 in the city, said living in a polluted area has become a way of life. "Air pollution is not just a seasonal issue. It's a year-round struggle that affects our health and daily lives. It's heartbreaking to see children and elderly suffer. We need more effective measures to ensure cleaner air for everyone," he said.

दिल्ली के कई इलाकों में सामान्य दो गुना तक बढ़ा ओजोन का स्तर, सेहत को पहुंचा रहा नुकसान

राजधानी के कई इलाकों में ओजोन का स्तर सामान्य से दो गुना तक पहुंच गया है। दिल्ली की हवा में प्रदूषण के स्तर पर नजर रखने वाली पृथ्वी विज्ञान मंत्रालय की संस्था सफर की रिपोर्ट के मुताबिक मंगलवार को मेजर ध्यानचंद नेशनल स्टेडियम के आसपास के इलाके में हवा में ओजोन का स्तर 239 माइक्रोग्राम प्रति क्यूबिक मीटर तक पहुंच गया। मानकों के तहत हवा में इसका स्तर अधिकतम 100 माइक्रोग्राम प्रति क्यूबिक मीटर से ज्यादा नहीं होना चाहिए। वैज्ञानिकों के मुताबिक कुछ समय पहले तक गर्मियों के मौसम में ही ओजोन के स्तर में बढ़ोतरी देखी जाती थी। लेकिन देश के कई हिस्सों में ये अब पूरे साल की समस्या बन गया है। हवा में ओजोन की मात्रा ज्यादा होने से हमारे फेफड़ों को नुकसान पहुंचता है। वहीं इससे दिल की बीमारी का भी खतरा बढ़ता है। ओजोन के प्रदूषण का कोई खास सोर्स नहीं होता है। बेहद गर्म मौसम में गाड़ियों और पावर प्लांट से निकलने वाला धुआं आपस में क्रिया करके ओजोन बनाने लगता और हवा में ओजोन का स्तर बढ़ने लगता है। सेंटर फॉर साइंस एंड एनवायरमेंट की एक रिपोर्ट के मुताबिक देश के कई शहरों में ओजोन के प्रदूषण के स्तर में चिंताजनक वृद्धि हुई है। इस साल गर्मियों में भारत के दस प्रमुख शहरों में ओजोन का स्तर खतरनाक स्तर तक बढ़ गया है। इनमें दिल्ली सबसे ज्यादा प्रभावित हुई। एयर क्वालिटी ट्रैकर एन इनविजिबल थ्रेट नाम से आई इस रिपोर्ट में प्रमुख रूप से दिल्ली, एनसीआर, बेंगलुरू, मुंबई, चेन्नई,कोलकाता, पुणे, ग्रेटर अहमदाबाद, ग्रेटर हैदराबाद, ग्रेटर जयपुर और ग्रेटर लखनऊ में ओजोन के स्तर का विश्लेषण किया गया। रिपोर्ट के मुताबिक इन शहरों में अप्रैल से जुलाई की तुलना में जनवरी से मार्च के बीच ओजोन के स्तर में कहीं अधिक बढ़ोतरी दर्ज की गई। अहमदाबाद में पिछले साल की तुलना में ओजोन के स्तर में 4000 गुना की बढ़ोतरी हुई है। वहीं पुणे में 500 और जयपुर में 152 फीसदी की बढ़ोतरी हुई है। सीएसई में वायु प्रदूषण पर लम्बे समय से काम कर रहे डॉक्टर विवेक चटोपाध्याय कहते हैं कि ओजोन के प्रदूषण की समस्या सिर्फ गर्मियों में होती थी, अब ये पूरे साल की समस्या बन गई है। खास तौर पर दक्षिण और पश्चिमी तटीय महानगरीय इलाकों में ये समस्या काफी बढ़ चुकी है। सामान्य तौर पर जब सूरज की रौशनी हो, गर्मी ज्यादा हो और गाड़ियों के धुएं का प्रदूषण हवा में मौजूद हो तो ही ओजोन के प्रदूषण में वृद्धि देखी जाती है। लेकिन हमने अध्ययन में पाया कि महानगरों में सूर्यास्त के बाद भी हवा में ओजोन का स्तर बढ़ा हुआ रहता है। ओजोन के प्रदूषण की खास बात ये है कि ये गैस के रूप में होती है। ऐसे में दिल्ली का ओजोन प्रदूषण हवा के साथ आसपास के ऐसे इलाके में पहुंच सकता है जहां प्रदूषण का कोई स्रोत न हो। ऐसे में इसके प्रदूषण की चपेट में काफी बड़े इलाके के लोग आ जाते हैं। सांसों पर बोझ बढ़ा रही ओजोन दिल्ली मेडिकल काउंसिल की साइंटिफिक कमेटी के चेयरमैन डॉक्टर नरेंद्र सैनी के मुताबिक हवा में ओजोन के स्तर का बढ़ना काफी खतरनाक है। ये सीधे हमारे फेफड़ों पर असर डालता है। हवा में ओजोन बढ़ने से सांस लेते समय छाती में दर्द, खांसी, गले में जलन और सांस की नली में सूजन जैसी दिक्कत हो सकती है। फेफड़ों के काम करने में कमी आ सकती है। ओजोन ब्रोंकाइटिस, अस्थमा इत्यादि को और खराब कर सकता है। ओजोन के कारण कार्डियोवैस्कुलर बीमारी हो सकती है जो दिल को प्रभावित करती है। बहुत लम्बे समय तक ओजोन के सांस के जरिए शरीर में जाने से कैंसर जैसी बीमारियों का खतरा भी हो सकता है। ओजोन का प्रदूषण पौधों को पहुंचा रहा नुकसान ओजोन की परत को नुकसान पहुंचने से दुनिया में मक्के के उत्पादन में कमी आ रही है। ये खुलासा यूएस एग्रीकल्चर डिपार्टमेंट की रिसर्च यूनिट USDA ARS Global Change and Photosynthesis Research Unit की ओर से किए गए अध्ययन में हुआ है। रिपोर्ट के मुताबिक ओजोन के निचले स्तर को नुकसान पहुंचने मक्के की फसल के उत्पादन में कमी आई है। ओजोन की निचली परत को नुकसान पहुंचने से सूरज की बहुत की ऐसी किरणें नीचे आ रही हैं जो मक्के की पत्तियों में कैमिकल संतुलन को बिगाड़ रही हैं। गौरतलब है कि सूरज से आने वाली पराबैंगनी किरणों को रोकने में ओजोन परत की महत्वपूर्ण भूमिका होगी। इस परत के चलते हम कई खतरनाक विकिरणों से बच पाते हैं। ओजोन की परत तब बनती है जब उद्योगों और गाड़ियों के धुएं में मौजूद नाइट्रस ऑक्साइड सूरज की रौशनी से टूट जाता है और ओजोन बनाने के लिए रासायनिक रूप से प्रतिक्रिया करता है। शिकागो स्थित इलिनोइस विश्वविद्यालय के शोधकर्ता 20 सालों से फसलों पर ओजोन प्रदूषण के प्रभावों का अध्ययन एक खास तरह के फॉर्म पर कर रहे हैं जहां ओजोन के अलग अलग स्तर का फसलों पर अध्ययन किया जा रहा है। अध्ययन करने वाले वैज्ञानिकों ने मक्के की तीन प्रजातियों पर अध्ययन किया। इसमें पाया गया कि ओजोन के प्रभाव के कारण हाइब्रिड फसलों की उपज में 25 फीसदी तक की कमी दर्ज की गई। वहीं पारंपरिक प्रजातियों के उत्पादन पर कुछ खास असर नहीं हुआ। वहीं हाइब्रिड मक्के के पौधे ओजोन के प्रभाव के चलते जल्दी बूढ़े होने लगे। ओजोन के चलते पौधों में ये बदलाव क्यों हो रहा है ये जानने के लिए वैज्ञानिकों ने पौधे की पत्तियों की रासायनिक बनावट का अध्ययन किया। स्टडी में पाया गया कि पारंपरिक प्रजाति के पौधे की पत्तियों में ओजोन के प्रभाव के चलते कुछ खास बदलाव नहीं हुआ। वहीं हाइब्रिड पौधे की पत्तियों में टोकोफेरोल और फाइटोस्टेरॉल कैमिकल की मात्रा बढ़ गई। ऐसे में इस स्टडी से साफ पता चला की हाइब्रिड प्रजातियां ओजोन के प्रति बेहद संवेदनशील हैं। पूर्व मुख्य तकनीकी सलाहकार एवं परियोजना प्रबंधक, विश्व खाद्य संगठन, (संयुक्त राष्ट्र संघ) डा. राम चेत चौधरी कहते हैं कि क्लाइमेट चेंज के साथ ही ओजोन की परत को नुकसान पहुंचने का सीधा असर फसलों पर पड़ता है। ओजोन के प्रभाव के चलते पौधे की पत्तियों में बनने वाली बहुत सी ऊर्जा नष्ट हो जाती है। साथ ही पत्तों में टिशूज को भी नुकसान पहुंचता है। हमें पर्यावरण को बेहतर बनाने के साथ ही आने वाले समय के लिए ज्यादा रजिस्ट्रेशन वाली प्रजातियों का विकास करने की जरूरत है। ये है बचाव सीएसई ने ओजोन प्रदूषण पर किए गए अपने अध्ययन में कुछ सुझाव दिए हैं। इसमें कहा गया है कि, ओजोन की जटिल रासायनिक संरचना के कारण इसे ट्रैक और नियंत्रित करना मुश्किल है। इसे ट्रैक और नियंत्रित करने के लिए एक व्यवस्था बनाए जाने की जरूरत है। वैश्विक अनुभवों के मुताबिक जैसे जैसे हवा में मौजूद प्रदूषण के कणों का स्तर गिरता है नाइट्रोजन ऑक्साइड और ग्राउंड लेवल ओजोन का स्तर बढ़ने लगता है। ऐसे में ओजोन को नियंत्रित करने के लिए उद्योगों, वाहनों, घरों और खुले में जलने से होने वाले उत्सर्जन को रोकने के लिए सख्त नियम होने चाहिए। ओजोन शहरों से दूर दूर तक फैल कर प्रदूषण में इजाफा करता है। इसके लिए स्थानीय और क्षेत्रीय स्तर पर निगरानी की जरूरत है।

How Africa can reduce GHG emissions

New study report by India-based think tank Centre for Science and Environment (CSE) highlights the continent’s potential in recycling industrial waste; calls for policy reforms, infrastructure investment, and industry-led collaborations to unlock the possibilities Lagos (Nigeria): Industrial waste contributes 30-40 per cent of total greenhouse gas (GHG) emissions in Africa. A new report released here today says the continent can reduce its emissions significantly if it recycles this waste by initiating and encouraging industrial waste circularity. The report, titled ‘Africa’s Wasted Potential: Unlocking industrial waste in circularity’, has been prepared and published by New Delhi (India)-based think tank Centre for Science and Environment (CSE). It was released in Lagos at a pan-Africa workshop jointly hosted by CSE and Nigeria’s National Environmental Standards and Regulations Enforcement Agency (NESREA). Speaking at the workshop, Ishita Garg, Programme Manager, Industrial Pollution, CSE said: “The CSE report uncovers the unexplored potential of industrial waste, a resource often ignored. Africa’s circular economy efforts have remained focused on plastic and municipal waste, and industrial waste has largely been overlooked. This report emphasises the urgency of addressing this issue and demonstrates how circular solutions can drive both economic growth and environmental sustainability.” Garg added: “The report stresses on the need to prioritise industrial waste and treat it as a resource and a development opportunity. By adopting circular practices, industries can lower raw material costs, improve energy efficiency, and reduce their GHG emissions while creating job opportunities.” A call to action: Lagos workshop brings key regulators together: The workshop in Lagos brought together regulators from Nigeria, Kenya, Ghana, Uganda and Tanzania and is aimed at having focussed discussions on strengthening regulations, encouraging industry participation, and creating financial incentives to enhance circularity across industrial sectors. Dr Christopher N Beka, Director-Inspection and Enforcement with NESREA represented Prof Innocent Barikor, Director General of the Agency, at the workshop. Speaking in the event, Dr Beka said: “Africa’s industrial sector has a unique opportunity to integrate waste circularity -- especially as much of the continent’s industrial infrastructure is yet to be built. Regulatory frameworks need to evolve to support industrial waste circularity at large scale. Strengthening policies and enhancing industry participation will be crucial in industrial waste sustainability goals.” Garg pointed out that “while Africa is projected to double its GHG emissions by 2050 in a business-as-usual scenario, scaling up circularity practices could present a significant opportunity to cut GHG emissions at both country and continent level”. The CSE report indicates that 100 per cent recycling of just four types of industrial waste -- lead acid battery, glass waste, cashew waste and e-waste -- could reduce 8.7 million tonne of CO₂, which is a 2 per cent reduction in total GHG emissions from the continent. While the opportunities are clear, the report also sheds light on the barriers that hinder progress on the ground. One of the major roadblocks in enhancing industrial waste circularity in Africa is the absence of comprehensive waste inventories on the type and quantity of industrial waste generated. The report says that many African countries that are experiencing rapid industrialization, lack data on industrial waste generation, including figures on recycling, reuse and disposal, making it difficult to track material flows and identify opportunities for circularity. Said Garg: “The absence of such information has resulted in dumping of waste like slag, fly ash, plastic, glass, paper, etc which are otherwise easily recyclable.”
