Routematic Accelerates Green Mobility with EV Rollout in Delhi-NCR

A recent Centre for Science and Environment (CSE) study identifies vehicular emissions as the leading cause of Delhi’s winter air pollution, surpassing stubble burning and road dust. With vehicles emitting over 50% more harmful pollutants than any other source, clean mobility is now central to the city’s fight for cleaner air. In a significant step toward building sustainable urban mobility and addressing the pressing issue of air pollution in the National Capital Region, Routematic, India’s leading AI-powered corporate commute platform, today announced the launch of its Electric Vehicle (EV) fleet in Delhi-NCR. This initiative is part of the company’s broader effort to decarbonise corporate transportation across India and aligns with the government’s push toward clean energy adoption. The company aims to deploy 1,000 EVs across Delhi-NCR by the end of the current financial year, reinforcing its commitment to cleaner, greener, and more sustainable corporate mobility solutions. Routematic’s newly launched EV fleet in Delhi-NCR aims to significantly reduce the tailpipe emissions and carbon footprint of corporate employee transportation by gradually replacing traditional fuel-based vehicles with zero-emission electric alternatives. Beyond emissions reduction, the platform’s proprietary AI powered routing algorithms and ride-sharing capabilities help reduce traffic congestion and idle time, two additional contributors to poor air quality in NCR. With Delhi consistently ranking among the most polluted cities in the world, vehicular emissions remain one of the key contributors to deteriorating air quality.

The expansion underscores our commitment to green mobility and further strengthens our role as a trusted partner in corporate transportation.” – said Sriram Kannan, Founder & CEO, Routematic.

Delhi breathes its cleanest July air in 10 years: Data released, here's what made it possible

The Central Pollution Control Board (CPCB) said that Delhi experienced its cleanest July air in a decade, mainly due to consistent rainfall on 23 out of 31 days. As of July 30, the monthly average Air Quality Index (AQI) stood at 79 -- classified as "Satisfactory" under CPCB's air quality rating system. CPCB began calculating the AQI in April 2015. It said July 2025's average AQI of 79 is significantly lower than previous years. In comparison, the average AQI was 96 in July 2024 and 83.67 in July 2023. The CPCB also shared data showing the AQI data for the last few years. Environment Minister credits multi-agency action Delhi's Environment Minister Manjinder Singh Sirsa had claimed on July 23 that the city was on track to witness its cleanest July in a decade. "This is not just a weather-driven phenomenon. It reflects the impact of Delhi’s multi-agency implementation model, sustained landfill action, intensive cleanliness drives, and a firm commitment to results-based governance," he added. Officials also noted that by July 23, Delhi had already seen 118 days of "Good", "Satisfactory" or "Moderate" air in 2025 -- matching the total for the entire year in 2024. Experts point to weather, not just policy However, air pollution experts remain cautious about the claims. Anumita Roychowdhury, air pollution specialist and Executive Director at the Centre for Science and Environment, said the improvement in air quality is largely weather-driven. "Monsoon rains wash away pollutants and bring down pollution levels. This year’s frequent and intense rainfall spells are the key factor," she said. On the government’s role, Roychowdhury added, "We don’t yet have comprehensive emissions data for such a short window. Monsoon is not the right season to measure the long-term effectiveness of policy interventions. We’ll need to watch the pollution levels during the winter to assess real progress.” Rainfall surpasses long-term average Delhi has already received more rainfall than the long-period average for July. As of Wednesday morning (8:30 AM), Safdarjung -- the city’s base weather station -- recorded 220.2 mm of rain, exceeding the long-term July average of 209.7 mm. By 5:30 pm on the same day, another 15 mm had been recorded. Other parts of the city also saw light to moderate showers. Palam weather station logged 4.6 mm in 24 hours until 8:30 am and 28.3 mm from 8:30 am to 5:30 pm. Pusa station recorded 37.5 mm and 12.5 mm during the same periods respectively, while Janakpuri saw 11.5 mm in the late afternoon. An official from the India Meteorological Department (IMD) said light to moderate rain is likely to continue on Thursday, followed by light rainfall, thunder, and lightning from Friday onwards.

Delhi Records Cleanest July Air In A Decade; Monsoon Rains, Gov't Efforts Debated

New Delhi has seen its cleanest air in July in a decade, a welcome development for which overall rainfall throughout the month is largely responsible. The monthly average Air Quality Index (AQI) of the capital was 79 up to July 30, a level that falls into the category of "satisfactory," data made available by the Central Pollution Control Board (CPCB) said. New Delhi has seen its cleanest air in July in a decade, a welcome development for which overall rainfall throughout the month is largely responsible. The monthly average Air Quality Index (AQI) of the capital was 79 up to July 30, a level that falls into the category of "satisfactory," data made available by the Central Pollution Control Board (CPCB) said. Delhi Environment Minister Manjinder Singh Sirsa had, on July 23, already indicated that July 2025 was set to be the cleanest in a decade, attributing the improvement to "Delhi’s multi-agency implementation model, continuous landfill action, intensified sweeping operations, and a clear commitment to outcome-based governance." Officials had also highlighted that Delhi had already clocked 118 days of "good," "satisfactory," or "moderate" air quality by July 23, matching the total recorded for the entire year of 2024. But air pollution specialist Anumita Roychowdhury, executive director at the Centre for Science and Environment, doubted the government's exclusive claim to credit. "The general enhancement in air quality is indeed a function of meteorological conditions. As it stands, the level of pollution decreases during monsoon months because of the washout effect, where pollutants evaporate owing to heavy rains. This year, we have seen regular bouts of heavy rains, which have definitely contributed," Roychowdhury said. She also warned against making final judgments on the long-term effect of the government during the monsoon season. "We do not have all the emissions data to be in a position to make such a comparison in such a short time frame. The monsoon season would not be the right time to make this sort of analysis. We need to observe how the level of pollution recovers during the winter months to determine if measures taken by the government are moving in the right direction." The Safdarjung weather office, the main meteorological observatory of Delhi, had accumulated 220.2mm of rain till 8:30 AM on Wednesday, which surpassed the long-term average for July of 209.7mm. The India Meteorological Department (IMD) added another 15mm of rain at Safdarjung till 5:30 PM on Wednesday. Other areas of the city too saw light to moderate showers, with the IMD predicting the same to prevail for the next couple of days in the form of very light to light rain and thunderstorms along with lightning from Friday onward. 28.3mm and 12.5mm were received at Palam and Pusa, respectively, between 8:30 AM and 5:30 PM on Wednesday.

In July 2025, the average air quality index in major cities like Ahmedabad, Bengaluru, Chennai, Gandhinagar, Jaipur, Mumbai, and Patna was recorded as “satisfactory”. Meanwhile, cities as Vapi, Visakhapatnam, Sri Ganganagar, Pali, Nandesari, Nagaur, Jalore, Jaisalmer, Durgapur, Bikaner, Byrnihat, Chhapra, and Barmer recorded “moderate”. This year, the majority of cities recorded “good” air quality. Interestingly, none fell into the “poor,” “very poor,” or “severe” categories. Highlighting overall improved air quality, an air pollution expert and executive director at the Centre for Science and Environment, Anumita Roychowdhury, in talks with Hindustan Times, stated that frequent rainfalls played a major role in air quality improvement. While the AQI improvement in Delhi is a major relief, we hope that this continues in the coming months, with the right measures, as well.

Cutting Forests, Cutting Corners: India’s forest policy is sabotaging its own climate goals

There is a systematic shift toward “industry-centric, technocratic approaches” that weaken community participation and scientific rigor in forest conservation, according to an earlier governance review by the Centre for Science and Environment, an advocacy group. The central government’s moves to dilute environmental safeguards, especially those governing forest land, may accelerate industrial growth in the short term, but it deeply undermines the country’s long-term climate commitments. This paradox is rooted in a dangerous false equivalence. A key concern is the increasing policy reliance on monoculture plantations as substitutes for natural forests. While plantations may provide fast economic and forestry outputs, scientific analyses consistently show that they fall far short of the carbon storage, biodiversity and ecosystem resilience provided by intact natural forests. This shift threatens the integrity of India’s carbon strategy and risks a major carbon sink shortfall—estimated at over 1 billion tonnes carbon dioxide equivalent by 2030—if current trends continue unchecked. Legislative changes weakening forest protection framework India’s forest protection framework has been weakened by major changes in laws and rules, chiefly through the Forest (Conservation) Amendment Act, 2023, and the Forest Conservation Rules of 2022. The amendment narrows the legal definition of “forest” to only areas officially notified or recorded as forest after October 25, 1980, and exempts lands converted to other uses before December 12, 1996. This excludes vast areas, including substantial “deemed forests,” from protection. It also introduces broad exemptions for strategic projects near borders, public infrastructure in security-affected districts, and certain linear projects, making large tracts of forest legally available for non-forest use. Simultaneously, the Forest Conservation Rules, 2022, erode community rights by removing gram sabha (village council) consent as a mandatory prerequisite for forest land diversion, instead allowing state governments and the Centre to approve projects without direct community consultation at the early stages. The new rules and the amendment Act further expand the list of permitted activities in forests, such as zoos, eco-tourism, and various infrastructure projects—even within ecologically sensitive areas—with most oversight shifted from local communities to central authorities. Fundamental shift These policy shifts represent a fundamental move toward prioritizing industrial, infrastructure and security interests over ecological and community safeguards. The dilution of definitions, removal of early-stage community consultation, and broadened exemptions collectively open up vast areas of forest to commercial and non-forest use, raising serious concerns among conservationists, policy analysts and rights advocates regarding the long-term impacts on biodiversity, local livelihoods, and India's climate commitments. The danger lies in a policy architecture that systematically undermines the carbon sequestration infrastructure upon which India’s climate commitments depend. By treating monoculture plantations as equivalent substitutes for natural forests while weakening the scientific rigor essential for credible climate action, these changes threaten to isolate Indian businesses from the climate-conscious global economy. At the heart of this miscalculation lies a misunderstanding of how carbon sequestration actually works. Research by The Energy and Resources Institute (TERI) on India’s carbon strategy demonstrates that achieving the committed 2.5-3 billion tonnes CO2 equivalent by 2030 requires genuine forest restoration, not plantation substitutes that masquerade as climate solutions. The distinction isn’t academic. It’s the difference between meeting India’s net zero commitments and falling catastrophically short. Erosion of carbon sequestration infrastructure An analysis by the Observer Research Foundation reveals the stark mathematics behind India’s forest challenge. While policy frameworks celebrate tree cover increases, 96 percent of tree cover loss from 2013 to 2019 occurred in natural forests, with intact forests accounting for only 6.7 percent of India’s total tree cover. This isn’t merely an ecological concern. It represents a systematic erosion of India’s carbon sequestration infrastructure when the country needs it most. Forest degradation already costs India 1.4 percent of GDP annually, according to a TERI analysis, a haemorrhaging that hastens as climate impacts intensify. Rather than stemming this loss, current policies appear designed to amplify it through weakened protections and scientifically questionable compensatory mechanisms that prioritize industrial access over economic stability. The global business community has grown increasingly explicit about the risks such policies create. KPMG’s Climate Risk Report emphasizes that ESG (environmental, social, and governance) considerations have become “virtually certain” regulatory requirements, with financial and reputational impacts for non-compliance now integrated as principal risks in enterprise risk management frameworks. The carbon credit market offers perhaps the most telling illustration of how diluted forest policies translate into commercial disadvantage. Nine renewable energy projects from India were among 47 projects worldwide producing “problematic credits” in 2024, with 80 percent of carbon credits from these major projects unable to reliably deliver promised emissions reductions due to lack of additionality, according to a study by Corporate Accountability, a civil society organisation. Quality deficit has commercial consequences When there is a demand for high-quality, verified carbon credits, India’s plantation-heavy approach fails to meet international quality standards. This is exemplified by PwC’s approach to carbon credit quality, with 87 percent of the consultancy’s portfolio coming from projects protecting natural environments. This quality deficit has immediate commercial consequences that extend beyond environmental compliance. In such a scenario, India’s compensatory afforestation programmes would struggle to meet “robust additionality, baseline, and monitoring, reporting, and verification frameworks,” according to a carbon market study by EY, which could potentially exclude Indian businesses from premium carbon markets and the substantial revenues they represent. There is a systematic shift toward “industry-centric, technocratic approaches” that weaken community participation and scientific rigor in forest conservation, according to an earlier governance review by the Centre for Science and Environment, an advocacy group. This trajectory contradicts global trends toward stakeholder engagement and transparency that international investors increasingly demand, signalling institutional weakness rather than business-friendly reform. India has nearly 140 million hectares of potential for forest protection and landscape restoration that could sequester 3-4.3 billion tonnes of above-ground carbon by 2040, found a restoration analysis by the World Resources Institute, a think tank. However, realizing this opportunity requires policy frameworks that recognize the fundamental distinction between genuine restoration and industrial plantation, the distinction that current policies systematically blur. High stakes for net zero ambitions India could potentially provide over 50 percent of total climate mitigation potential through agricultural and forestry interventions, but the integrity of these solutions depends critically on maintaining scientific rigor in distinguishing between natural ecosystems and commercial plantations, said an analysis of nature-based solutions by PwC. The consultancy’s emphasis on verifiable emissions reductions directly contradicts the plantation-as-forest substitution that underlies current policy thinking. India needs to invest $1.5 trillion by 2030 for climate action at scale, according to estimates by a climate investment analysis by Deloitte. Weak forest policies that generate questionable offsets rather than genuine carbon sequestration will exclude Indian businesses from this massive financing opportunity while undermining the country's credibility in international climate negotiations. India’s current forest policy trajectory represents more than an environmental misstep. It’s a strategic blunder that threatens to strand the country’s businesses in an increasingly unforgiving global marketplace where climate credibility determines access to capital, markets and partnerships. India’s forests represent more than carbon sinks. They constitute strategic infrastructure whose protection determines whether the country can honour its climate commitments while preserving economic competitiveness. The current policy trajectory jeopardizes both objectives simultaneously, creating vulnerabilities that extend well beyond environmental concerns to the fundamental architecture of India’s economic future.

Earthquake rocks Russia, ripples reach US; will climate change end geopolitical wars?

“Nature spares no one, not even superpowers,” noted environmentalist Sunita Narain, emphasizing the need for global cooperation. The UN has repeatedly called for collective action to curb emissions, yet major powers remain distracted by arms races and trade wars, diverting resources from climate resilience. The world, on Wednesday, July 30, awoke to chaos as a massive 8.8-magnitude earthquake struck Russia’s Kamchatka Peninsula, the strongest in the region since 1952. Hours later, tsunami waves up to 4 metres high crashed into the coasts of Russia and Japan, triggering evacuations and causing structural damage. The tremors’ ripple effects were felt as far away as the U.S. West Coast, where rising water levels and strong currents sparked alarm. This natural disaster, reminiscent of the catastrophic 2004 Indian Ocean tsunami that killed over 230,000 people across 14 countries, underscores the indiscriminate fury of nature. As geopolitical tensions, from the Ukraine war to U.S.-Russia rivalries, dominate global discourse, the earthquake and tsunami serve as a grim reminder that climate change and natural calamities are humanity’s true common enemies, demanding urgent, united action. The Kamchatka earthquake, centered off Russia’s eastern coast, unleashed waves that battered coastal towns, uprooting infrastructure and forcing thousands to flee to higher ground. Japan, no stranger to seismic activity, activated its early warning systems, evacuating coastal areas in Hokkaido and Tohoku. The Japan Meteorological Agency reported minor injuries but no fatalities, though damaged buildings and disrupted power lines painted a picture of disarray. Across the Pacific, the U.S. National Tsunami Warning Center issued alerts for California, Oregon, and Washington, as tidal surges caused flooding in low-lying areas. The U.S. Geological Survey noted that the quake’s transcontinental impact highlights the interconnectedness of global geophysical systems, a reality often overshadowed by political rivalries. The 2004 Indian Ocean tsunami, triggered by a 9.1–9.3-magnitude quake near Sumatra, remains a haunting benchmark. It devastated coastal communities in Thailand, Sri Lanka, India, and beyond, displacing millions and exposing the vulnerability of densely populated coastlines. India’s Andaman and Nicobar Islands and Tamil Nadu bore heavy losses, with over 12,000 deaths. The 2025 Kamchatka event, while less deadly, reignites fears of such catastrophes, particularly as climate change amplifies their severity. Rising sea levels, melting glaciers, and destabilized coastal sediments—driven by human-induced greenhouse gas emissions—make tsunamis more destructive. In countries like Japan, Indonesia, Bangladesh, and coastal India, even a modest 0.5-meter sea-level rise can double the impact of tsunami surges, according to a 2023 UN Climate Report. Climate change is no longer a distant threat but a present crisis, disrupting economies and lives across every continent. The Paris Agreement, effective since November 4, 2016, urges nations to limit global temperature rise to below 2°C, ideally 1.5°C, to mitigate climate impacts. Yet, global emissions continue to climb, with 2024 recording a 1.3 percent increase in CO2 levels, per the International Energy Agency. Changing weather patterns, rising sea levels, and extreme events like heatwaves and floods are now commonplace. In India, erratic monsoons and coastal erosion threaten livelihoods, with 40 percent of the population living in vulnerable coastal areas, as per the Ministry of Environment. The Kamchatka tsunami underscores how climate factors, such as warming oceans, intensify natural disasters, making them more frequent and far-reaching. The irony is stark: while nations like the US and Russia remain locked in geopolitical tussles—evident in the ongoing Ukraine conflict and Cold War-era rivalries—they face a shared adversary in climate-induced disasters. The US, despite its economic might, saw its Pacific coast rattled by the Kamchatka quake’s aftershocks. Russia, grappling with its own economic sanctions, now faces reconstruction costs in Kamchatka. “Nature spares no one, not even superpowers,” noted environmentalist Sunita Narain, emphasizing the need for global cooperation. The UN has repeatedly called for collective action to curb emissions, yet major powers remain distracted by arms races and trade wars, diverting resources from climate resilience. India, too, is at a crossroads. Its 7,500-km coastline, home to bustling ports and tourist hubs, is increasingly at risk. The National Disaster Management Authority (NDMA) has invested in early warning systems since 2004, saving lives in events like Cyclone Amphan in 2020. However, rising sea levels threaten cities like Mumbai and Chennai, with a 2024 World Bank study estimating USD 1.2 trillion in potential losses by 2050 if climate measures falter. India’s push for renewable energy, targeting 500 GW by 2030, is commendable, but it must accelerate adaptation strategies like mangrove restoration and coastal defenses to mitigate tsunami risks.

दिल्ली में 10 साल बाद सबसे साफ हवा, AQI आंकड़े कर रहे राहत की तस्दीक

विशेषज्ञ इस दावे को लेकर संदेह में हैं. सेंटर फॉर साइंस एंड एनवायरनमेंट की वायु प्रदूषण विशेषज्ञ और कार्यकारी निदेशक अनुमिता रॉयचौधरी ने बताया कि वायु गुणवत्ता में सुधार मौसम की परिस्थितियों का परिणाम है. उन्होंने कहा कि मानसून के दौरान भारी बारिश के कारण प्रदूषक पानी में मिल जाते हैं, जिससे प्रदूषण का स्तर घटता है. इस वर्ष लगातार हो रही तीव्र बारिश को इस स्थिति का मुख्य कारण माना गया है. पिछले एक दशक में जुलाई का महीना दिल्ली के लिए सबसे स्वच्छ रहा, जहां औसत वायु गुणवत्ता सूचकांक (AQI) 79 दर्ज किया गया, जो 2015 के बाद का सबसे कम आंकड़ा है. हाल ही में हुई रुक-रुक कर बारिश ने दिल्ली की वायु को साफ करने में महत्वपूर्ण भूमिका निभाई है, जिससे पूरे सप्ताह के दौरान वायु गुणवत्ता में सुधार देखने को मिला है. AQI में सुधार के पीछे बारिश का एक महत्वपूर्ण कारण है. केंद्रीय प्रदूषण नियंत्रण बोर्ड के आंकड़ों के अनुसार, दिल्ली में पिछले दस वर्षों में जुलाई का महीना सबसे अधिक स्वच्छ रहा. लगातार हो रही बारिश के कारण वायु गुणवत्ता में सुधार होता रहा, जिससे दिल्ली की हवा ने पिछले एक दशक के रिकॉर्ड को तोड़ दिया. बीते सालों में जुलाई के महीने में दिल्ली की हवा बीते वर्षों में जुलाई के दौरान दिल्ली का वायु गुणवत्ता सूचकांक (AQI) विभिन्न स्तरों पर रहा है. 2015 में यह 138.13, 2016 में 145.64, 2017 में 98.39, 2018 में 103.83, 2019 में 134, 2020 में 83.80, 2021 में 110.06, 2022 में 87.29, 2023 में 83.67, 2024 में 96 और 2025 में 79 दर्ज किया गया है. यह 2025 का AQI पिछले वर्षों की तुलना में सबसे कम है, जो वायु गुणवत्ता में सुधार का संकेत देता है. सामान्य से अधिक हुई बारिश जुलाई महीने में बारिश की मात्रा औसत से अधिक रही है, और शहर के विभिन्न क्षेत्रों में लगातार वर्षा हो रही है. भारत मौसम विज्ञान विभाग (IMD) ने आज दिल्ली और उसके आसपास के क्षेत्रों में तेज बारिश की संभावना जताई है. इसके साथ ही, 31 जुलाई को बारिश के लिए यलो अलर्ट भी जारी किया गया है. AQI कितना बेहतर दिल्ली और एनसीआर में लगातार बारिश के कारण वायु गुणवत्ता सूचकांक में सुधार हुआ है. जुलाई महीने में औसत AQI 79 दर्ज किया गया, जो 2015 के बाद से सबसे कम है. यह AQI संतोषजनक श्रेणी में आता है. केंद्रीय प्रदूषण नियंत्रण बोर्ड (सीपीसीबी) के अनुसार, AQI को 0 से 50 के बीच अच्छा, 51 से 100 के बीच संतोषजनक, 101 से 200 के बीच मध्यम, 201 से 300 के बीच खराब, 301 से 400 के बीच बहुत खराब और 401 से 500 के बीच गंभीर माना जाता है. वायु प्रदूषण विशेषज्ञ ने क्या कहा? विशेषज्ञ इस दावे को लेकर संदेह में हैं. सेंटर फॉर साइंस एंड एनवायरनमेंट की वायु प्रदूषण विशेषज्ञ और कार्यकारी निदेशक अनुमिता रॉयचौधरी ने बताया कि वायु गुणवत्ता में सुधार मौसम की परिस्थितियों का परिणाम है. उन्होंने कहा कि मानसून के दौरान भारी बारिश के कारण प्रदूषक पानी में मिल जाते हैं, जिससे प्रदूषण का स्तर घटता है. इस वर्ष लगातार हो रही तीव्र बारिश को इस स्थिति का मुख्य कारण माना गया है. रॉयचौधरी ने सरकार के योगदान पर टिप्पणी करते हुए कहा कि सीमित समय में सभी उत्सर्जन डेटा की तुलना करना संभव नहीं है. मानसून के मौसम में इस तरह के आकलन करना उचित नहीं होगा. सर्दियों के महीनों में प्रदूषण के स्तरों का विश्लेषण करना आवश्यक है, ताकि यह पता चल सके कि सरकार की पहल सही दिशा में प्रगति कर रही हैं या नहीं. सामान्य से अधिक हुई बारिश जुलाई में बारिश की मात्रा पहले के औसत से अधिक रही है. दिल्ली के सफदरजंग मौसम केंद्र ने बुधवार सुबह 8:30 बजे तक 220.2 मिमी बारिश रिकॉर्ड की, जबकि इसका लंबा अवधि का औसत 209.7 मिमी है. इसी दिन शाम 5:30 बजे तक इस केंद्र ने 15 मिमी और बारिश दर्ज की. शहर के विभिन्न क्षेत्रों में हल्की से मध्यम बारिश हुई. पालम मौसम केंद्र ने बुधवार सुबह 8:30 बजे तक पिछले 24 घंटों में 4.6 मिमी और सुबह 8:30 से शाम 5:30 बजे के बीच 28.3 मिमी बारिश रिकॉर्ड की. इसी समय में पूसा स्टेशन पर क्रमशः 37.5 मिमी और 12.5 मिमी बारिश हुई, जबकि जनकपुरी स्टेशन में देर दोपहर 11.5 मिमी बारिश हुई. भारत मौसम विज्ञान विभाग (IMD) के एक अधिकारी के अनुसार, गुरुवार को भी हल्की से मध्यम बारिश की संभावना बनी रहेगी, जबकि शुक्रवार से बहुत हल्की से हल्की बारिश, गरज और बिजली गिरने की घटनाएं देखी जा सकती हैं.

Delhi breathes its cleanest July air in 10 years

Anumita Roychowdhury, an air pollution expert and executive director at the Centre for Science and Environment, said, “The overall improvement in air quality is certainly a reflection of meteorological conditions. As it is, the pollution levels go down during the monsoon months due to the wash-out effect, whereby pollutants dissipate because of heavy showers. This year, we have observed frequent spells of intense rain, which have certainly played a role.” Propelled by regular rainfall on 23 of 31 days this month, the Capital has recorded its cleanest air for the month of July over the past 10 years, according to data shared by the Central Pollution Control Board (CPCB). Until July 30, the monthly average air quality index (AQI) has been 79, which is classified as “satisfactory”, according to CPCB’s categorisation. The average AQI in July 2024 was 96, and in July 2023, it was 83.67. To be sure, CPCB began calculating AQI from April 2015. CPCB classifies AQI between 0 and 50 as “good”, between 51 and 100 as “satisfactory”, between 101 and 200 as “moderate”, between 201 and 300 as “poor”, between 301 and 400 as “very poor”, and over 400 as “severe”. The highest AQI average in July was 145.64, recorded in 2016. The average AQI for July in 2022 was 87.29; 110.06 in 2021; 83.80 in 2020; 134 in 2019; 103.83 in 2018; 98.39 in 2017; and 138.13 in 2015. In July 2025, until the 30th, Delhi recorded 28 “satisfactory” air days and two “moderate” air days. The best AQI recorded this month was 51—on the brink of good air—on July 15, and the worst was 136, recorded on July 26. In July 2024, Delhi recorded 14 “moderate” air days and 17 “satisfactory” air days, with the highest AQI, at 138, recorded on July 11. The lowest AQI recorded in July last year was 56, clocked between July 8 and 9. Delhi environment minister Manjinder Singh Sirsa, on July 23, said that Delhi was on its way to record its cleanest July in a decade. He had said, “This is not a seasonal blip — it is the result of Delhi’s multi-agency implementation model, continuous landfill action, intensified sweeping operations, and a clear commitment to outcome-based governance.” Providing data on the same, officials had also said that Delhi had been witnessing a major turnaround in its air quality, with 2025 already having clocked 118 days of “good”, “satisfactory” or “moderate” air quality — matching the total number recorded in all of 2024, as of July 23. However, experts remained sceptical. Anumita Roychowdhury, an air pollution expert and executive director at the Centre for Science and Environment, said, “The overall improvement in air quality is certainly a reflection of meteorological conditions. As it is, the pollution levels go down during the monsoon months due to the wash-out effect, whereby pollutants dissipate because of heavy showers. This year, we have observed frequent spells of intense rain, which have certainly played a role.”

Policy experts, civil society from Asia Pacific discuss country positions ahead of plastics treaty talks

Siddharth Ghanshyam Singh, Centre for Science & Environment (CSE) said, “The moment to push for ambition is now. Opportunities like this don’t come often, and countries must remember who they are negotiating for; their people and our shared planet. We cannot allow a few vocal opponents to derail and delay progress. It’s time to stand firm and take a decisive step toward ending plastic pollution.” Regional policy experts discussed country positions and negotiation dynamics of the Asia Pacific region, in a briefing by Break free from Plastic (BFFP), the global movement working to achieve a future free from plastic pollution, ahead of the INC 5.2 negotiations for the Global Plastic Treaty in Geneva, Switzerland from August 5-14, 2025. INC-5.2 refers to the second part of the fifth session of the Intergovernmental Negotiating Committee (INC). It discussed how countries frame their priorities around economic development, environmental protection, and regional and international cooperation. Asia Pacific countries sit at the epicentre of both plastic production and pollution impacts; the region's diverse economies and environmental challenges make it a key battleground in the global treaty negotiations. The negotiations outcome will determine global standards for plastic production, waste management, and industry accountability. The briefing also identified key challenges, including procedural issues affecting civil society access, potential delaying tactics, watered-down commitments favouring waste management over production caps, and industry influence promoting circular economy narratives over substantive pollution reduction. For more nuanced coverage of the treaty, the policy experts and researchers on the panel urged journalists to consider a human rights-centric, fossil-fuel-free development model for Asia Pacific. It was felt critical threats that could significantly weaken the treaty include chemical and plastic-producing countries challenging the treaty's scope to address the full plastics lifecycle, potentially removing obligations for primary plastic polymer production reduction and chemicals of concern from the final agreement. The most significant risk is that negotiations could result in a framework convention with voluntary measures rather than legally binding obligations, which would fundamentally undermine the treaty's ability to address global plastic pollution at the required scale and speed. A critical political obstacle to a strong, effective treaty is the decision-making process, which relies on a consensual decision-making process where all countries are not equal, instead of an equal voting process. With pressure to reach a consensus, countries may compromise on stronger provisions to secure a deal, with critical decisions on production reduction measures deferred to future COP processes. As diverse as the Asia Pacific region is, we are most impacted by plastic pollution, and often bear disproportionate blame. C Semee Rhee, Global Policy Advisor, BFFP said “It's not about whether or not we will have a treaty. It's about how many countries will be courageous enough to say that we can no longer continue producing the amount of plastics we currently produce for the sake of the environment and human well-being.” Siddharth Ghanshyam Singh, Centre for Science & Environment (CSE) said, “The moment to push for ambition is now. Opportunities like this don’t come often, and countries must remember who they are negotiating for; their people and our shared planet. We cannot allow a few vocal opponents to derail and delay progress. It’s time to stand firm and take a decisive step toward ending plastic pollution.” Pinky Chandran, Asia Pacific Coordinator, BFFP said “The plastic problem often resembles a kaleidoscope, with no single perspective illuminating the complete picture; in fact, each turn reveals a new representation. We must view the plastic problem as a tapestry, where every element is interconnected, interlinked, and interdependent. A fragmented, piecemeal approach simply won't suffice. And so there must be global binding measures to reduce plastic production, in order to tackle the plastic pollution problem, through just transition lens”. Siddika Sultana, Executive Director, Environment and Social Development Organization (ESDO) said "South Asia is both a significant hotspot for plastic pollution and a center of innovation. To address this issue effectively, the region must shift from isolated national initiatives to coordinated regional action. A united approach—supported by enforcement, investment, and inclusivity—can establish South Asia as a leader in developing an effective global treaty on plastic waste." Punyathorn Jeungsmarn, Plastics Campaign Researcher, Environmental Justice Foundation said, “As a region, Southeast Asia is particularly affected by plastic pollution, and is increasingly becoming the dumping ground for plastic waste, misguided false solutions such as waste-to-energy technologies, and petrochemical expansion. It is therefore crucial for our representatives to stand up and put people and the planet over plastics and the petrochemical industry. Throughout the past rounds of negotiations, we have seen courageous stances from Southeast Asian countries. We hope to see those again in Geneva.”

10 साल बाद दिल्ली वालों ने ली सबसे साफ सांस! जुलाई में हुआ ये कारनामा, जानें इसके पीछे की असली वजह

सेंटर फॉर साइंस एंड एनवायरनमेंट की वायु प्रदूषण विशेषज्ञ अनुमिता रॉयचौधरी ने कहा, "वायु गुणवत्ता में सुधार मौसम की वजह से है। केंद्रीय प्रदूषण नियंत्रण बोर्ड (CPCB) द्वारा साझा किए गए आंकड़ों के अनुसार, दिल्ली में इस जुलाई में लगातार 23 दिन बारिश होने के कारण पिछले 10 सालों म

बारिश ने बदली दिल्ली की फिजा, एक दशक बाद रही सबसे साफ हवा वाली जुलाई

सेंटर फॉर साइंस एंड एनवायरनमेंट की कार्यकारी निदेशक अनुमिता रॉयचौधरी का कहना है कि बारिश का 'वॉश-आउट प्रभाव' हवा को साफ करने में बड़ा कारक रहा। भारी बारिश प्रदूषकों को धो देती है और इस साल बारिश की लगातार बौछारों ने इसमें अहम भूमिका निभाई। वे कहती हैं, 'सरकारी कदमों का सही आकलन सर्दियों में होगा, जब प्रदूषण का स्तर फिर बढ़ता है।' दिल्ली की हवा इस जुलाई दशक की सबसे साफ रही। CPCB के मुताबिक, औसत AQI 79 रहा जो कि संतोषजनक श्रेणी में आता है। महीने के 23 दिन बारिश ने प्रदूषण धोया। सरकार का कहना है कि उनके प्रयासों से 2025 में 118 दिन स्वच्छ हवा रही। इस जुलाई में दिल्ली ने एक नया रिकॉर्ड बनाया है। 31 में से 23 दिन बारिश की फुहारों ने राजधानी की हवा को इतना साफ कर दिया कि यह पिछले दस सालों में जुलाई का सबसे साफ हवा वाला महीना बन गया। सेंट्रल पॉल्यूशन कंट्रोल बोर्ड (CPCB) के आंकड़ों के मुताबिक, 30 जुलाई तक इस महीने का औसत वायु गुणवत्ता सूचकांक (AQI) 79 रहा, जो "संतोषजनक" श्रेणी में आता है। राजधानी में बादल-बारिश का सिलसिला जारी है। मौसम के कारकों के चलते हवा साफ-सुथरी बनी हुई है। बुधवार शाम चार बजे तक एक्यूआई 66 अंक था, जो संतोषजनक स्तर पर रहा। पिछले साल यानी जुलाई 2024 में औसत AQI 96 था, जबकि 2023 में यह 83.67 रहा। सीपीसीबी के अनुसार, एक्यूआई अगर 0 से 50 तक हो तो ‘अच्छा’, 51 से 100 तक ‘संतोषजनक’, 101 से 200 ‘मध्यम’ और उससे अधिक ‘खराब’ या उससे ऊपर की श्रेणियों में आता है। अगले दो दिनों के बीच वायु गुणवत्ता का यह साफ-सुथरा स्तर बना रहेगा। सरकारी प्रयासों का कमाल या प्रकृति का करिश्मा? दिल्ली के पर्यावरण मंत्री मंजिंदर सिंह सिरसा ने 23 जुलाई को दावा किया कि यह स्वच्छता कोई मौसमी संयोग नहीं, बल्कि दिल्ली सरकार के ठोस कदमों का नतीजा है। उन्होंने लैंडफिल प्रबंधन, सड़कों की सफाई और परिणाम-उन्मुख शासन पर जोर दिया। आंकड़े बताते हैं कि 2025 में 23 जुलाई तक दिल्ली ने 118 दिन 'अच्छी', 'संतोषजनक' या 'मध्यम' हवा वाले दर्ज किए, जो पूरे 2024 के बराबर है। लेकिन विशेषज्ञ इस दावे पर पूरी तरह सहमत नहीं। सेंटर फॉर साइंस एंड एनवायरनमेंट की कार्यकारी निदेशक अनुमिता रॉयचौधरी का कहना है कि बारिश का 'वॉश-आउट प्रभाव' हवा को साफ करने में बड़ा कारक रहा। भारी बारिश प्रदूषकों को धो देती है और इस साल बारिश की लगातार बौछारों ने इसमें अहम भूमिका निभाई। वे कहती हैं, 'सरकारी कदमों का सही आकलन सर्दियों में होगा, जब प्रदूषण का स्तर फिर बढ़ता है।'

क्या दिल्ली अब सांस लेने लायक बन रही है, जुलाई ने रच दिया 10 साल का रिकॉर्ड

सेंटर फॉर साइंस एंड एनवायरनमेंट की अनुमिता रॉयचौधरी का कहना है कि यह सुधार अस्थायी है और मुख्य भूमिका मानसून की है, जिसने प्रदूषकों को धोकर हटा दिया। उन्होंने चेताया कि मानसून के दौरान प्राप्त आंकड़ों से स्थायी नीतिगत सुधारों का मूल्यांकन नहीं किया जा सकता। राजधानी के निवासियों ने इस जुलाई कुछ ऐसा अनुभव किया जो आमतौर पर दुर्लभ होता है अपेक्षाकृत साफ़ हवा। केंद्रीय प्रदूषण नियंत्रण बोर्ड (CPCB) के आंकड़े बताते हैं कि जुलाई 2025 में दिल्ली की वायु गुणवत्ता पिछले दस वर्षों की तुलना में सबसे बेहतर रही। लेकिन इस सुधार के पीछे असल वजह क्या है बेहतर नीतियां या मौसम की मेहरबानी?बारिश ने साफ की दिल्ली की फिजाजुलाई में लगभग पूरे महीने हुई नियमित और जोरदार बारिश ने दिल्ली की हवा को कई स्तरों पर शुद्ध किया। 31 में से 23 दिनों में बारिश होने के चलते वायुमंडल में मौजूद प्रदूषक कण बह गए, जिससे हवा में पारदर्शिता बढ़ी और AQI यानी एयर क्वालिटी इंडेक्स गिरकर 79 तक पहुँच गया, जो "संतोषजनक" श्रेणी में आता है।यह स्तर पिछले वर्षों की तुलना में काफी नीचे है — 2024 में यही औसत AQI 96 और 2023 में 83.67 था। CPCB की निगरानी के अनुसार, 2016 के 145.64 के उच्चतम जुलाई AQI के मुकाबले यह आंकड़ा उल्लेखनीय रूप से बेहतर है।जनजीवन पर असर: सांस लेना हुआ आसानहवा की इस बेहतरी का असर आम लोगों की दिनचर्या पर भी महसूस किया गया। खासकर बुजुर्गों, बच्चों और अस्थमा के मरीजों ने राहत की सांस ली। पार्कों और खुली जगहों में टहलने वालों की संख्या बढ़ी और अस्पतालों में श्वास संबंधी बीमारियों की रिपोर्टिंग में भी कुछ गिरावट देखी गई।सरकारी दावे बनाम वैज्ञानिक नजरियादिल्ली के पर्यावरण मंत्री मनजिंदर सिंह सिरसा ने हवा में सुधार का श्रेय सरकार की बहु-स्तरीय कार्रवाई को दिया। उन्होंने इसे केवल मानसून की देन नहीं, बल्कि स्वच्छता अभियानों, लैंडफिल प्रबंधन और नीतिगत दृढ़ता का परिणाम बताया।हालांकि पर्यावरण विशेषज्ञों का नजरिया कुछ अलग है। सेंटर फॉर साइंस एंड एनवायरनमेंट की अनुमिता रॉयचौधरी का कहना है कि यह सुधार अस्थायी है और मुख्य भूमिका मानसून की है, जिसने प्रदूषकों को धोकर हटा दिया। उन्होंने चेताया कि मानसून के दौरान प्राप्त आंकड़ों से स्थायी नीतिगत सुधारों का मूल्यांकन नहीं किया जा सकता।बारिश के आंकड़े क्या कहते हैं?सफदरजंग मौसम केंद्र ने 30 जुलाई तक 220.2 मिमी बारिश दर्ज की, जो कि जुलाई की दीर्घकालिक औसत 209.7 मिमी से ऊपर है। दिन भर में हुई और बारिशों को मिलाकर यह आँकड़ा और बढ़ा। राजधानी के अन्य क्षेत्रों — पालम, पूसा और जनकपुरी — में भी लगातार हल्की से मध्यम बारिश होती रही, जिससे पूरे शहर का पर्यावरण कुछ दिन के लिए ही सही, पर सांस लेने लायक बना।

दिल्लीवालों को 10 साल बाद मिली सबसे साफ हवा, आकंड़े हुए जारी, जाने कितना है AQI

पिछले एक दशक में जुलाई का महीना दिल्ली के लिए सबसे स्वच्छ रहा, जहां औसत वायु गुणवत्ता सूचकांक (AQI) 79 दर्ज किया गया, जो 2015 के बाद का सबसे कम आंकड़ा है. हाल ही में हुई रुक-रुक कर बारिश ने दिल्ली की वायु को साफ करने में महत्वपूर्ण भूमिका निभाई है, जिससे पूरे सप्ताह के दौरान वायु गुणवत्ता में सुधार देखने को मिला है. AQI में सुधार के पीछे बारिश का एक महत्वपूर्ण कारण है. केंद्रीय प्रदूषण नियंत्रण बोर्ड के आंकड़ों के अनुसार, दिल्ली में पिछले दस वर्षों में जुलाई का महीना सबसे अधिक स्वच्छ रहा. लगातार हो रही बारिश के कारण वायु गुणवत्ता में सुधार होता रहा, जिससे दिल्ली की हवा ने पिछले एक दशक के रिकॉर्ड को तोड़ दिया. बीते वर्षों में जुलाई के दौरान दिल्ली का वायु गुणवत्ता सूचकांक (AQI) विभिन्न स्तरों पर रहा है. 2015 में यह 138.13, 2016 में 145.64, 2017 में 98.39, 2018 में 103.83, 2019 में 134, 2020 में 83.80, 2021 में 110.06, 2022 में 87.29, 2023 में 83.67, 2024 में 96 और 2025 में 79 दर्ज किया गया है. यह 2025 का AQI पिछले वर्षों की तुलना में सबसे कम है, जो वायु गुणवत्ता में सुधार का संकेत देता है. सामान्य से अधिक हुई बारिश जुलाई महीने में बारिश की मात्रा औसत से अधिक रही है, और शहर के विभिन्न क्षेत्रों में लगातार वर्षा हो रही है. भारत मौसम विज्ञान विभाग (IMD) ने आज दिल्ली और उसके आसपास के क्षेत्रों में तेज बारिश की संभावना जताई है. इसके साथ ही, 31 जुलाई को बारिश के लिए यलो अलर्ट भी जारी किया गया है. AQI कितना बेहतर दिल्ली और एनसीआर में लगातार बारिश के कारण वायु गुणवत्ता सूचकांक में सुधार हुआ है. जुलाई महीने में औसत AQI 79 दर्ज किया गया, जो 2015 के बाद से सबसे कम है. यह AQI संतोषजनक श्रेणी में आता है. केंद्रीय प्रदूषण नियंत्रण बोर्ड (सीपीसीबी) के अनुसार, AQI को 0 से 50 के बीच अच्छा, 51 से 100 के बीच संतोषजनक, 101 से 200 के बीच मध्यम, 201 से 300 के बीच खराब, 301 से 400 के बीच बहुत खराब और 401 से 500 के बीच गंभीर माना जाता है. वायु प्रदूषण विशेषज्ञ ने क्या कहा? विशेषज्ञ इस दावे को लेकर संदेह में हैं. सेंटर फॉर साइंस एंड एनवायरनमेंट की वायु प्रदूषण विशेषज्ञ और कार्यकारी निदेशक अनुमिता रॉयचौधरी ने बताया कि वायु गुणवत्ता में सुधार मौसम की परिस्थितियों का परिणाम है. उन्होंने कहा कि मानसून के दौरान भारी बारिश के कारण प्रदूषक पानी में मिल जाते हैं, जिससे प्रदूषण का स्तर घटता है. इस वर्ष लगातार हो रही तीव्र बारिश को इस स्थिति का मुख्य कारण माना गया है. रॉयचौधरी ने सरकार के योगदान पर टिप्पणी करते हुए कहा कि सीमित समय में सभी उत्सर्जन डेटा की तुलना करना संभव नहीं है. मानसून के मौसम में इस तरह के आकलन करना उचित नहीं होगा. सर्दियों के महीनों में प्रदूषण के स्तरों का विश्लेषण करना आवश्यक है, ताकि यह पता चल सके कि सरकार की पहल सही दिशा में प्रगति कर रही हैं या नहीं. सामान्य से अधिक हुई बारिश जुलाई में बारिश की मात्रा पहले के औसत से अधिक रही है. दिल्ली के सफदरजंग मौसम केंद्र ने बुधवार सुबह 8:30 बजे तक 220.2 मिमी बारिश रिकॉर्ड की, जबकि इसका लंबा अवधि का औसत 209.7 मिमी है. इसी दिन शाम 5:30 बजे तक इस केंद्र ने 15 मिमी और बारिश दर्ज की. शहर के विभिन्न क्षेत्रों में हल्की से मध्यम बारिश हुई. पालम मौसम केंद्र ने बुधवार सुबह 8:30 बजे तक पिछले 24 घंटों में 4.6 मिमी और सुबह 8:30 से शाम 5:30 बजे के बीच 28.3 मिमी बारिश रिकॉर्ड की. इसी समय में पूसा स्टेशन पर क्रमशः 37.5 मिमी और 12.5 मिमी बारिश हुई, जबकि जनकपुरी स्टेशन में देर दोपहर 11.5 मिमी बारिश हुई. भारत मौसम विज्ञान विभाग (IMD) के एक अधिकारी के अनुसार, गुरुवार को भी हल्की से मध्यम बारिश की संभावना बनी रहेगी, जबकि शुक्रवार से बहुत हल्की से हल्की बारिश, गरज और बिजली गिरने की घटनाएं देखी जा सकती हैं.

Kolkata beats other metros, reports more than 50% of good air days in 4 years: CSE study

The findings, part of CSE's State of India's Environment in Figures 2025, analysed air quality data from Jan 1, 2021 to March 31, 2025. KOLKATA: The city has taken the top spot with the best air quality among six key Indian metros, a study by Centre for Science and Environment (CSE) has revealed. Kolkata witnessed 791 days - over 50% of the total 1,550 days assessed - of 'very good' and 'satisfact-ory' air quality, highest among the metros. The findings, part of CSE's State of India's Environment in Figures 2025, analysed air quality data from Jan 1, 2021 to March 31, 2025. According to the study, Kolkata reported 368 days of 'very good' air and 423 days of 'satisfactory' air during this period. While only 231 days of 'moderate' air was recorded in the city, not a single day was reported in the 'severe' category. With fewer 'poor' and 'very poor' air quality days - 513 and 15 respectively - Kolkatans faced limited exposure to harmful pollution levels, which in turn meant better health, the analysis highlighted. Delhi remained the most polluted metro during the study period, with 396 'moderate', 265 'poor' and 62 'very poor' air quality days. Significantly, the national capital's 284 'severe' air days was in sharp contrast to Kolkata's nil, an indication of the former's prolonged hazardous pollution levels. "Kolkata's success story is a result of several key policy decisions by PCB and their effective implementation by the local bodies," said West Bengal Pollution Control Board chairman Kalyan Rudra. "Using sprinklers to prevent dust-resuspension, deploying fire tenders at landfills, biomining of garbage heaps, shifting to clean fuel, use of smokeless chullah by food vendors and urban and rural poor have all been crucial in improving the city's air quality," he added. Rudra, however, cautioned that significant challenges remained in reducing emissions further. Kolkata beats other metros, reports more than 50% of good air days in 4 years: CSE study 'Clean Air project helps Kol improve AQI management' Anumita Roychowdhury, an air quality expert with CSE, said the Centre's National Clean Air Programme (NCAP) helped track pollution levels and undertake remedial measures. Under the NCAP monitoring and compliance system, cities report their progress on the Central Pollution Control Board's PRANA portal, every quarter, defining the scope of action, setting targets to reduce pollution and indicating funding. "The performance-linked NCAP framework helped lay the foundations of national air quality management in non-attainment cities, such as Kolkata," said Roychowdhury. Bengaluru, Hyderabad and Chennai recorded a high number of 'poor' AQI days, but dodged 'very poor' or 'severe' days, owing to their locations, weather and pollution sources. Air pollution in southern metros is primarily driven by vehicular emissions, dust and industrial activities. Mumbai presented a hybrid pattern. The city saw 145 'very good', 637 'satisfactory', 118 'moderate' and 649 'poor' AQI days. It largely stayed clear of 'very poor' and 'severe' levels, recording only one 'very poor' day and zero 'severe' days.

Delhi worst, Kolkata best: CSE study ranks air quality in Indian metros

Analysis by the CSE, detailed in its annual State of India’s Environment in Figures 2025, recorded Kolkata having 791 days where air quality was described as either 'very good' or 'satisfactory.' Kolkata has emerged as the Indian metro with the cleanest air quality, overtaking its larger rivals over a four-year period, according to new research published by the Centre for Science and Environment (CSE). The report, highlighted by TOI, places the city well ahead of Delhi, Mumbai, Bengaluru, Hyderabad and Chennai for the number of days with 'very good' and 'satisfactory' air quality out of 1,550 days tracked between January 2021 and March 2025. Analysis by the CSE, detailed in its annual State of India’s Environment in Figures 2025, recorded Kolkata having 791 days where air quality was described as either 'very good' or 'satisfactory.' The Bengal capital enjoyed 368 days of 'very good' and 423 days of 'satisfactory' air, with only 231 days falling under the 'moderate' category and, notably, not a single day rated as 'severe.' This stands in sharp contrast to Delhi, which endured 284 days of 'severe' air, the highest in the country. The CSE findings underline the health implications for citizens, noting that with just 513 'poor' and 15 'very poor' air quality days, Kolkata residents were largely shielded from prolonged hazardous pollution. The city’s relative success has been credited to a combination of policies and innovations steered by local authorities and the West Bengal Pollution Control Board (PCB). PCB chairman Kalyan Rudra was cited by TOI as saying that the city’s improved air quality was due to a series of strategic actions, including "using sprinklers to prevent dust-resuspension, deploying fire tenders at landfills, biomining of garbage heaps, shifting to clean fuel, use of smokeless chullah by food vendors and urban and rural poor." He added, "Kolkata’s success story is a result of several key policy decisions by PCB and their effective implementation by the local bodies." Rudra, however, emphasised that persistent efforts are needed to further reduce emissions.

Meghalaya Receives 56% Less Rainfall This Monsoon Amid Changing Climate Patterns

Meghalaya recorded the highest rainfall deficit among all the states and Union Territories (UT) of the country at 56% during the Southwest Monsoon (SWM) season of 2025. Despite being wetter historically, Meghalaya received less rainfall this monsoon than the drier state of Jharkhand, reported Down To Earth. Meghalaya, in northeastern India, is called the ‘Abode of Clouds’ due to its near-permanent presence of clouds and accompanying heavy rain. The state also houses two of the rainiest places in the world, Mawsynram and Cherrapunji where 83% of the population depends on rain-fed agriculture and 48% of the land is cultivable, according to Down To Earth.
