PARIVARTAN Scheme: Replacing Polluting Vehicles in Delhi-NCR

Why in News?

The Union government plans to replace over two lakh trucks and buses in Delhi-NCR with BS-VI-compliant or electric vehicles within a year. This advances the two-year implementation period originally approved for the PARIVARTAN Scheme.

According to government estimates, trucks and buses constitute only 3.1% of NCR’s vehicle fleet but contribute around 36% of its vehicular PM2.5 emissions.

About PARIVARTAN Scheme: 

PARIVARTAN stands for Programme for Accelerated Renewal and Incentivization of Vehicle Assets for Reducing Transport Air Pollution and Network Emissions.

• Launched in July 2026.
• Covers eligible trucks and buses registered in Delhi and NCR districts of Haryana, Rajasthan and Uttar Pradesh.
• Targets vehicles conforming to BS-IV or older emission norms.
• Funded through the National Capital Region Planning Board under the Ministry of Housing and Urban Affairs.
• Implemented by the Ministry of Road Transport and Highways.
• Total outlay: ₹9585 crore, including ₹5041 crore in Central budgetary support.

Incentives Offered: 

Eligible vehicle owners receive:

• 5% interest subvention on vehicle loans for five years
• complete road-tax waiver for 10 years
• exemption from registration fees
• at least 8% manufacturer discount on the ex-showroom price
• monthly fuel vouchers of ₹1,200-₹4,800 for five years for eligible BS-VI diesel or CNG vehicles; and
• one-time incentives of ₹64,000-₹2.56 lakh for electric vehicles.

Owners must scrap BS-III or older vehicles. BS-IV vehicles may either be scrapped or sold outside the NCR. 

Significance: 

• High-impact targeting: Replacing a relatively small number of high-emitting commercial vehicles can produce disproportionate reductions in particulate matter and nitrogen oxide emissions.
• Cleaner urban transport: Electric buses and trucks eliminate tailpipe emissions, while BS-VI vehicles use cleaner fuel and advanced emission-control systems.
• Health benefits: Lower vehicular pollution can reduce respiratory and cardiovascular illnesses.
• Fleet modernisation: Interest support and tax waivers reduce the cost of replacing ageing commercial vehicles.
• Regional approach: Coverage across the NCR recognises that Delhi’s air pollution transcends administrative boundaries. 

Implementation Concerns: 

• High upfront costs and limited heavy-vehicle charging infrastructure may constrain electric-vehicle adoption. 
• Selling BS-IV vehicles outside the NCR may merely shift pollution to other regions.
• BS-VI diesel vehicles still generate carbon emissions and may create long-term fossil-fuel lock-in.
• Real-world emission reductions depend on proper maintenance, clean fuel and effective pollution-under-control testing.
• Transparent scrappage, recycling and beneficiary verification will be essential.

The scheme should prioritise zero-emission buses and urban freight vehicles, establish heavy-duty charging corridors and strengthen remote-sensing-based emission monitoring. 

Vehicle replacement must be integrated with cleaner fuels, public transport expansion, freight rationalisation and strict enforcement against end-of-life vehicles.
