The Supreme Court recalled its Vanashakti judgment of May 16, 2025 that had banned retrospective environmental clearances. The matter is now referred to a larger bench.

• Original judgment: the Vanashakti case (May 2025) struck down a 2017 notification by the Ministry of Environment, Forest and Climate Change (MoEFCC) and related office memoranda from 2021. These had allowed project developers to obtain environmental clearances post-facto for violations already committed.
• Basis of the original ban: the Court held that allowing ex-post-facto clearances incentivises non-compliance with environmental law, because developers can build first and seek permission later.
• Reason for recall: the majority on the bench found that a blanket prohibition would cause "devastating consequences" for ongoing infrastructure and development projects that had relied on the earlier regulatory framework in good faith.
• Dissent: Justice Bhuyan dissented from the recall. He argued that retrospective clearances "reward illegal behaviour" and restore the perverse incentive the original judgment sought to eliminate.
• Current status: the question is referred to a larger bench for definitive resolution. Until that bench rules, the policy landscape on ex-post-facto clearances remains unsettled.
• Legal context: the Environment (Protection) Act 1986 and the Environmental Impact Assessment (EIA) Notification 2006 are the statutory bases for environmental clearances. The 2017 MoEFCC notification introduced remediation rather than rejection for violators.

UNEP's Global Methane Status Report 2025 finds that the world is far off track on the Global Methane Pledge's 30% reduction target for 2030.

• Current trajectory: at present national policies, 2030 methane emissions will reach 369 million tonnes (Mt). This is only 4% lower than the 2021 baseline.
• Global Methane Pledge (GMP): launched at COP26 in 2021. Over 150 countries pledged to cut methane emissions by 30% below 2021 levels by 2030.
• NDC implementation gap: even if all countries fully implement their Nationally Determined Contributions, the result is only an 8% reduction by 2030 , far short of the 30% GMP target.
• Maximum Technically Feasible Reductions (MTFR): if all technically available mitigation measures are deployed, a 32% cut is achievable. This would avoid 0.2 degrees Celsius of additional warming by 2050.
• Sectoral breakdown of mitigation potential:
  • Energy sector: 72% of the 2030 mitigation potential.
  • Agriculture: 18%.
  • Waste: 10%.
• Countries with GMP-comparable targets: only Canada, Japan, Moldova, Norway, the United States, and Vietnam have domestic methane commitments comparable to the GMP's 30% ambition.
• India context: India is a signatory to the GMP but methane from rice paddies and livestock is a major component of India's agriculture emissions.
