Conservation, Pollution & EIA

A newspaper report has highlighted growing concerns among motorists and automakers over India’s rapid shift to E20 fuel, especially regarding mileage loss, older vehicle compatibility, corrosion risk, lack of fuel choice at petrol pumps and the possible move towards higher ethanol blends such as E25, E85 and E100. The issue is important for UPSC because it links energy security, biofuel policy, automobile regulation, consumer protection, agriculture, emissions and India’s transition towards cleaner transport fuels.

The Directorate General of Lighthouses and Lightships (DGLL), through its Port Blair (Sri Vijaya Puram) directorate, has sought clearance from the Andaman and Nicobar Islands Coastal Zone Management Authority and the Environment Ministry to undertake protection and development work — including a convention centre and a museum — at Indira Point, India's southernmost point on Great Nicobar Island. The site falls in the highly protected ICRZ-IA and ICRZ-IVA categories, where most construction is prohibited. This article explains what Indira Point is, the Island Coastal Regulation Zone framework under the CRZ Notification, 2019, why the location is ecologically sensitive, and the conservation-versus-development questions the proposal raises.

The Zoological Survey of India has identified four sites on the west coast of Great Nicobar Island for translocating coral colonies and giant clams likely to be affected by the proposed Galathea Bay transshipment port under the Great Nicobar mega project. The development has revived UPSC-relevant questions on coral reef conservation, environmental clearance, ICRZ rules, Schedule-I species, tribal safeguards and the balance between strategic infrastructure and fragile island ecology.

A new Indicators of Global Climate Change study has reported that human-induced global warming reached its highest recorded level in 2025, mainly due to continued greenhouse gas emissions from fossil fuels, industry, land-use change and weakening aerosol cooling. The issue is important for UPSC because it connects climate science, Paris Agreement targets, carbon budgets, energy transition, India’s NDCs, climate justice and disaster-risk planning.

The Maharashtra government has exempted a large iron-ore mining and processing project in Gadchiroli from wildlife clearance, stating the site does not fall in any tiger corridor — a claim that official maps and the NTCA-approved Tiger Conservation Plan appear to contradict. The project, involving diversion of 9.4 sq km of forest land by Lloyds Metals & Energy, overlaps the ecologically vital Tadoba–Indravati tiger corridor. This article explains what a tiger corridor is, the legal framework under the Wildlife (Protection) Act, 1972 (Section 38-O), Project Tiger, NTCA, the difference between forest, wildlife and environmental clearances, the role of the Forest Rights Act and PESA, and the development-versus-conservation debate this case raises.

The Wildlife Institute of India (WII) has prepared a 10-year management plan for Delhi's only wildlife sanctuary — Asola Bhatti Wildlife Sanctuary in the Aravalli range — revealing that the invasive alien tree species Prosopis Juliflora (Vilayati Kikar) alone covers a staggering 63.48% of the sanctuary's landscape, posing a severe ecological threat. This article explains the WII management plan in detail, the invasive species crisis, the Aravalli–Delhi Ridge ecology, biological invasion impacts, India's legal framework on Invasive Alien Species under the Wildlife (Protection) Act and Convention on Biological Diversity, and the broader conservation challenges facing Delhi's last green lung.

While many parts of India are struggling with the LPG crisis caused by rising prices and supply issues due to the West Asia conflict, the small village of Ekauni in Chandauli district of Uttar Pradesh remains completely untouched. All 500 residents here cook using piped biogas produced from cow dung in a community plant set up in 2022. The story highlights how a simple, locally managed biogas system can provide reliable and cheap clean cooking fuel to rural families.

Israeli airstrikes on March 7-8, 2026, targeted oil storage facilities in Tehran and Alborz province, causing massive fires that released harmful pollutants into the air. This led to "black rain" falling over Tehran on March 8, a mix of rain and toxic particles that has raised serious health and environmental concerns, with the World Health Organization warning of long-term risks like respiratory issues and ecosystem damage.

The United States has eased some sanctions on Venezuela, allowing American companies like Chevron to increase imports of its heavy crude oil. This move, highlighted in recent reports, aims to match the needs of US Gulf Coast refineries while keeping global oil prices stable amid rising domestic production of light oil. Venezuela, with the world's largest heavy oil reserves, is seeing a revival in exports to the US after years of restrictions, signaling a pragmatic shift in US energy policy in 2026.

Renowned ecologist and environmentalist Madhav Gadgil passed away at the age of 83 after a brief illness, leading to renewed discussions on his pioneering 2011 Western Ghats Ecology Expert Panel (WGEEP) report. This report highlighted the need for strict conservation in the ecologically fragile Western Ghats region, but it faced significant opposition from states and industries, resulting in its partial implementation through a diluted version.

The Standing Committee of the National Board for Wildlife has recommended approval for 12 key defence projects in Ladakh's protected wildlife sanctuaries, citing the need for high operational preparedness due to increasing assertiveness by China's People's Liberation Army along the Line of Actual Control, following lessons from the 2020 border conflicts.

Delhi's air quality plunged to a 'very poor' level with an AQI of 301 on October 27, 2025, prompting the government to prepare for a cloud seeding operation on October 28 if weather permits, aiming to trigger artificial rain and flush out pollutants. In parallel, the Commission for Air Quality Management (CAQM) enforced a ban on non-BS-VI commercial goods vehicles entering the city from November 1, under GRAP Stage II, to curb rising vehicular emissions as stubble burning and post-Diwali haze intensify the annual winter pollution spike, affecting millions in the national capital.

The Supreme Court relaxed the absolute ban on firecrackers in Delhi-NCR, allowing the use of green crackers on a test case basis during Diwali. This order, passed by a bench led by Chief Justice DY Chandrachud, aims to find a middle ground between cultural practices and the growing public health crisis from air pollution, as complete bans have proven hard to enforce and led to smuggling of more harmful crackers.

The Supreme Court has relaxed the complete ban on firecrackers in Delhi-NCR for Diwali, permitting the sale and use of green crackers on a trial basis for two days from October 18 to 20, 2025, with specific timings, following requests from the Centre and considering enforcement challenges, to test if regulated use can balance cultural celebrations with air quality protection amid rising pollution concerns.

The Finance Ministry has granted in-principle approval for the construction of Maitri II, India's newest research station in eastern Antarctica, marking a significant step in upgrading the country's polar research infrastructure. This decision, announced on October 4, 2025, comes as the existing Maitri station, operational since 1989, has outlived its original design life and requires replacement to support ongoing scientific expeditions amid growing global interest in Antarctic studies for climate insights and resource exploration.

On October 9, 2025, the Supreme Court of India issued an order pausing all work on Haryana's proposed jungle safari park in the Aravalli hills, following a petition highlighting potential ecological harm. This decision comes amid growing debates on balancing development projects like eco-tourism with the protection of fragile ecosystems, especially in the Aravallis, which serve as a vital green barrier for northern India.

US President Donald Trump's recent speech at the United Nations General Assembly, where he labeled climate change predictions as the "greatest con job" and claimed they were made by "stupid people" costing fortunes, has sparked renewed scrutiny on the reliability of climate models. These tools are essential for forecasting climate impacts, including in India where erratic monsoons, heatwaves, and sea-level rise threaten agriculture, water security, and coastal communities, urging a deeper look into their workings and accuracy to inform policy and adaptation strategies.

The Ministry of Environment, Forest and Climate Change (MoEFCC) has issued an office memorandum exempting mining projects for atomic, critical, and strategic minerals from mandatory public consultations under the Environment Impact Assessment (EIA) Notification, 2006. This step, reported by The Indian Express on September 11, 2025, responds to requests from the Ministry of Defence and the Department of Atomic Energy (DAE), aiming to expedite clearances for minerals vital to national security, defence equipment, and atomic energy programs amid India's heavy import dependence. The move aligns with recent policy shifts to boost domestic production but has raised questions about environmental transparency and community involvement.

The Union government has approved the expansion of the Sundarbans Tiger Reserve in West Bengal by 1,044 sq km, making it the second-largest tiger reserve in India after the Nagarjunasagar-Srisailam Tiger Reserve.
