The Union Cabinet’s 2-year Clean Mobility Scheme for NCR — incentivising replacement of pre-BS-VI trucks and buses — fuses environmental federalism with the CAQM Act 2021 and the constitutional duty under Article 48A.
On June 5, 2026, the Union Cabinet cleared a two-year Clean Mobility Scheme for Delhi-NCR, providing fiscal incentives for fleet owners to scrap and replace pre-Bharat Stage VI (BS-VI) commercial trucks and buses. The transport sector contributes over 40% of NCR’s PM2.5 load, with older diesel commercial vehicles disproportionately responsible. The scheme will operate through the Commission for Air Quality Management (CAQM) — the statutory body created by the CAQM Act 2021 — and dovetails with the National Clean Air Programme (NCAP) target of 40% PM reduction by 2026 over a 2017 baseline.
📜 Constitutional / Statutory Anchor
CAQM Act 2021: creates a statutory Commission for Delhi-NCR with override powers over state pollution control boards. Article 48A: Directive Principle mandating State to protect and improve the environment. Article 51A(g): Fundamental Duty of every citizen to protect natural environment. Air (Prevention and Control of Pollution) Act 1981: parent statute for ambient air quality. MC Mehta v UoI: the continuing-mandamus line of cases that introduced CNG buses, banned firecrackers and triggered odd-even — judicial origin of NCR pollution governance.
Doctrinally, the scheme reflects the shift from judicially-driven environmental governance (the MC Mehta era) to a statutory framework. The Supreme Court in Subhash Kumar v State of Bihar (1991) read the right to a pollution-free environment into Article 21, and the precautionary and polluter-pays principles were domesticated in Vellore Citizens Welfare Forum v UoI (1996). BS-VI norms — equivalent to Euro-VI — were leapfrogged from BS-IV in April 2020, skipping BS-V entirely. This scheme operationalises the constitutional vision through targeted subsidy rather than outright ban, addressing transition-equity concerns of small fleet owners.
🎯 Key Facts at a Glance
- Cabinet approval: June 5, 2026; duration 2 years
- Target: pre-BS-VI trucks and buses in Delhi-NCR
- Transport share in NCR PM pollution: 40%+
- CAQM Act 2021: statutory regulator for NCR air quality
- BS-VI rollout: April 1, 2020 (leapfrogged from BS-IV)
- NCAP target: 40% PM reduction by 2026 vs 2017 baseline
Internationally, London’s Ultra Low Emission Zone (ULEZ) and Beijing’s vehicle-scrappage incentives offer comparators. The EU’s Euro-7 norms (effective 2025) target real-driving emissions, particulate brake-wear and tyre-wear — areas BS-VI does not cover. India’s leapfrog from BS-IV to BS-VI cost the auto industry around ₹70,000 crore in investment but yielded an 80% NOx reduction in diesel and 25% in petrol. The CAQM model itself is novel — replacing the older Environment Pollution Control Authority (EPCA) created under Supreme Court orders with a statutory body.
⚖️ CLAT Angle
Strong Polity + Environmental Law overlap. Expect a passage on the MC Mehta continuing-mandamus jurisprudence with questions linking Article 21 to environmental rights, the polluter-pays principle, and CAQM’s override powers. Current Affairs MCQs may test BS-VI rollout date, CAQM Act year and NCAP targets. A Legal Reasoning principle could pose Article 48A as a non-justiciable DPSP that nonetheless animates Article 21 interpretation.
Watch next: scheme guidelines and per-vehicle subsidy slabs will be notified by the Ministry of Heavy Industries within 30 days. The CAQM’s GRAP (Graded Response Action Plan) winter 2026-27 may tighten in tandem. A parallel push on CNG/LNG corridors and electric heavy-duty trucks under the PM E-DRIVE scheme is expected. Watch also for inter-state harmonisation since NCR spans Delhi, Haryana, UP and Rajasthan — a federal coordination challenge the CAQM was designed to solve.
💡 Why This Matters for CLAT 2027 Aspirants
Pair this with CLAT 2023’s environmental rights passage. Memorise the MC Mehta CNG-bus timeline, the precautionary + polluter-pays principles from Vellore Citizens, and the trio Article 21 + 48A + 51A(g). CAQM Act 2021 is a hot statutory anchor.
