Key Procedural Directions (Core Outcome)
The Court formally disposes of this long‑pending environmental PIL (W.P. (C) No. 13029/1985), noting that its scope has vastly expanded through hundreds of IAs and that a more organised structure is now necessary. It directs the Supreme Court Registry to register five new Suo Motu Writ Petitions (Civil), each focused on a distinct cluster of air‑pollution issues in the National Capital Region:
- “Curbing Air Pollution in the National Capital Region – Regulatory and Policy Framework, Air Quality Governance and other Ancillary Issues”– Policy issues in an evolving regulatory regime; transition to airshed-level governance; vacancies in regulatory agencies; data accuracy and transparency; improved enforcement; increasing green cover in NCR.
- “Curbing Air Pollution in the National Capital Region – Vehicular Emissions and Pollution”– ECC payment; registration of lower BSES vehicles; public transport; vehicular emissions; fuel standards; traffic enforcement; cleaner freight movement.
- “Curbing Air Pollution in the National Capital Region – Conservation and Enhancement of Green Cover”– Cutting of trees in NCR; protection of the Delhi Ridge and Morphological Ridge forest; tree census; enhancement of tree coverage.
- “Curbing Air Pollution in the National Capital Region – Pollution by Construction Activities, Power Plants, and Other Industries”– Fuel transition; issuance and compliance with emission standards for all industrial sources; and compensation of workers affected by suspension of work.
- “Curbing Air Pollution in the National Capital Region – Solid Waste Management and Burning of Crop Residue and Firecrackers”– Compliance with Solid Waste Management Rules 2016; landfill management; waste‑to‑energy plants; and implementation of policies on stubble burning and firecrackers.
The Court also issues a structured mechanism to classify and dispose of pending IAs and tagged matters, involving both Advocates‑on‑Record and the amici curiae, with presumptive infructuousness if no steps are taken by 15.05.2026, and with transfer of surviving issues into the appropriate new suo motu matters.
Brief Summary (Three Sentences)
This judgment formally closes the long‑running environmental PIL M.C. Mehta v. Union of India (W.P. (C) No. 13029/1985), which has since the 1980s driven major anti‑pollution measures in the National Capital Region, including the creation of the CAQM and implementation of GRAP. Recognising that the case has accumulated an unwieldy range of issues and IAs, the Supreme Court restructures its oversight by directing the registration of five new focused suo motu writ petitions dealing respectively with policy/regulatory governance, vehicular emissions, green cover, industrial and construction pollution, and solid waste/stubble burning/firecrackers. All existing orders in this PIL continue to operate, while a detailed procedure is laid down for classifying, closing or transferring outstanding IAs and tagged matters into the new suo motu cases.
