On 3 June 2026, the Union Cabinet approved a two-year scheme to replace BS-IV and older trucks and buses in Delhi-NCR with BS-VI or electric vehicles. It has a ₹9,585 crore outlay, involves four states and rests on the emissions comparison that one pre-BS vehicle equals 14 BS-VI vehicles.
Why in the News
The PMIndia Cabinet release of 3 June states that funding will run through NCRPB under the Ministry of Housing and Urban Affairs. Implementation involves the Ministries of Road Transport and Highways and Petroleum and Natural Gas, alongside Delhi, Haryana, Rajasthan and Uttar Pradesh. The stated ₹9,585 crore outlay includes ₹5,041 crore from the Centre and estimated state tax concessions of ₹1,601 crore.
About 2.07 lakh owners are expected to benefit: 1.91 lakh trucks and 16,329 buses. The rationale uses ARAI-TERI's 2018 source-apportionment findings: transport accounts for 14% of NCR's PM2.5, 40% of CO and 63% of NOx. Trucks and buses form only 3% of the fleet but produce 36% of transport-sector PM2.5.
The Emissions Arithmetic: A Small Fleet, a Large Share
The ARAI-TERI report of August 2018 attributes 36% of transport PM2.5 to trucks and buses despite their 3% fleet share. One pre-BS heavy vehicle emits as much as 14 BS-VI vehicles, while a BS-IV vehicle emits 2.7 times as much as a BS-VI vehicle. Replacing the most polluting 3% can therefore yield disproportionate reductions.
Key Facts
- Framework: Two years; ₹9,585 crore, including ₹5,041 crore from the Centre and about ₹1,601 crore in state tax concessions. NCRPB under MoHUA finances it; MoRTH and MoPNG implement it.
- Eligible vehicles: Delhi-NCR-registered BS-IV or older trucks and buses replaced by BS-VI, stricter-standard or electric vehicles. Government vehicles are excluded.
- Beneficiaries: About 2.07 lakh owners, comprising 1.91 lakh trucks and 16,329 buses across Delhi, Haryana, Rajasthan and Uttar Pradesh.
- Replacement rules: BS-III and older vehicles must be scrapped at registered facilities. BS-IV vehicles may be scrapped or sold outside NCR in non-NCAP cities. In Delhi, light goods vehicles must be electric, and buses BS-VI CNG or electric.
- Incentives: The Centre offers 5% interest subvention for five years, monthly fuel vouchers up to ₹4,800 depending on category, one-time EV benefits and CoD trading. States offer registration-fee waivers, motor-vehicle tax concessions for ten years of up to 100% on new vehicles and 50% on old vehicles, and waiver of old arrears. OEMs offer an 8% ex-showroom discount.
- Governance: An empowered committee chaired by the Cabinet Secretary includes the NITI Aayog CEO, relevant secretaries and state chief secretaries. Collectors/DMs operate at district level. A fully digital portal supports eligibility checks and monitoring.
Three Layers: Air Quality, Transport Economics and Regional Coordination
- Air quality: Source apportionment supports replacing the dirtiest vehicles first, with reductions much larger than the fleet average.
- Transport economics: A new vehicle is a major capital expense for small truck owners. Interest support, tax concessions, OEM discounts and scrap value jointly reduce switching costs.
- Regional coordination: NCR spans four states. NCRPB financing and the empowered committee provide an interstate platform, extending regional experimentation from crop-residue management to vehicles.
Analysis and Way Forward
First, combining central, state and OEM incentives addresses the owner's actual cost of replacement. The five-year benefit period alongside a two-year enrolment window intentionally encourages early enrolment. Second, allowing BS-IV sales outside NCR may relocate pollution. The non-NCAP-city condition seeks to contain leakage, but the source also warns of pressure on NCAP cities and stronger demands for a national phase-out.
Third, implementation depends on consistent state tax concessions, sufficient scrapping capacity and accessible portal operations. Success should be judged by actual replacements and measured emissions reductions, which the source says portal monitoring provides for. These figures reflect the 3 June 2026 Cabinet release; enrolment progress needs NCRPB/MoRTH records.
Distinguishing the Concepts
The general scrappage framework under the 2021 vehicle-fitness rules differs from this targeted, incentive-based NCR replacement scheme. BS-VI regulates new-vehicle emissions, whereas the scheme manages the existing fleet by removing older vehicles. NCAP's non-attainment-city programme and NCR-specific action are complementary, but the non-NCAP sales condition must be noted.
Mains Perspective
GS-III: Environmental pollution, urbanisation and infrastructure. Use attributed ARAI-TERI emissions figures, the scheme's finance, incentives and governance, regional-coordination lessons and pollution-leakage risks.

Answer Outline
Introduction: The factual summary of the scheme.
Main Body: The case: source-apportionment data, disproportionate benefits, multi-level incentives. Risks: pollution relocation, inequality between states, capacity. The way: a national phase-out, measured-emissions evaluation.
Conclusion: Test targeted replacement by linking it to the cost to small owners, coordination among states and scrapping capacity; decide success by vehicles actually replaced and measured emission reductions. Keep the risk of pollution relocation through external sale of old vehicles in view, and do not write the 2018 source data as a new survey of the current fleet.
Sources
The Hindi source states that key facts were checked against the PMIndia Cabinet release and that ARAI-TERI figures are quoted there.
Remember: A 3% fleet share causing 36% of emissions supports targeted replacement, but actual replacements and measured air-quality outcomes, not incentives alone, are the test.
