India approves AIS-228, an IIT Delhi-developed retrofit standard cutting emissions from pre-BS6 trucks and buses by up to 90%, offering an alternative to scrapping.
Key points
- Government Approves AIS-228 Retrofit Standard
- How Much The Retrofit Actually Cuts Emissions
- How Parivartan And Retrofitting Now Overlap
- Progress On Scrapping Centres So Far
- The Tension Gadkari Acknowledged Openly
Owners of ageing diesel trucks and buses in Delhi-NCR just got a third option beyond scrapping or buying new. The government has cleared AIS-228, a retrofit emission-control standard built on IIT Delhi research, capable of bringing a BS4 vehicle's emissions down to roughly BS6 levels without replacing the vehicle entirely.

Union Minister Nitin Gadkari announced the approval while speaking at the Society of Indian Automobile Manufacturers' 66th Annual Convention, describing it as a genuine third path for vehicles that fail current pollution norms, alongside the existing options of scrapping or outright replacement.
How Much The Retrofit Actually Cuts Emissions
According to Gadkari, the device developed from IIT Delhi research can reduce particulate matter emissions from pre-BS6 heavy vehicles by up to 90%, and nitrogen oxide emissions by up to 60%. A retrofitted BS4 vehicle would then perform roughly in line with a BS6 vehicle on emissions, without the owner needing to buy an entirely new truck or bus.
For fleet operators sitting on older vehicles that would otherwise face compliance issues, this is a meaningfully cheaper path forward than replacement, particularly for operators who can't easily absorb the upfront cost of a full new truck purchase right now.
How Parivartan And Retrofitting Now Overlap
This retrofit announcement lands squarely in the middle of Parivartan, the federal scheme approved in June to replace more than two lakh ageing trucks and buses registered across Delhi and neighbouring NCR districts in Haryana, Rajasthan and Uttar Pradesh. The scheme carries a total outlay of ₹9,585 crore, including ₹5,040 crore in central budgetary support.
Manufacturers like Ashok Leyland and Switch Mobility became the first OEMs to join this replacement scheme, which offers a 10-year road tax waiver, registration fee exemption, purchase discounts and fuel vouchers to owners scrapping BS4-and-older vehicles for BS6 or electric replacements.

Progress On Scrapping Centres So Far
Gadkari said more than 1,300 truck and bus owners have already registered under the Parivartan scheme, and the government has overshot its original target of 50 scrapping centres in the region, with 53 now operational and five more in the pipeline.
Buyers curious about how the used vehicle market in the affected region currently looks can browse used buses for sale in Delhi, giving a sense of the kind of ageing fleet this entire policy push is aimed at addressing.
The Tension Gadkari Acknowledged Openly
What makes this announcement genuinely interesting is that Gadkari didn't dodge the obvious tension it creates. Speaking directly to automakers in the room, he admitted the retrofit option might not be good news for the industry, since it gives operators a cheaper alternative to buying new vehicles outright, potentially denting demand the Parivartan scheme was designed to generate.
He still called it a good innovation, though, and urged manufacturers to draw more on Indian engineering talent as emissions standards keep tightening, pointing specifically to IIT graduates as a source of low-cost, forward-looking solutions. With trucks and buses making up roughly 3% of Delhi-NCR's vehicle fleet but generating about 36% of the region's PM2.5 emissions, the government is clearly betting on both scrappage and retrofitting together, rather than picking just one lever. Fleet owners exploring cleaner alternatives can also look at the current bus price list for BS6 and electric options entering the market.

Frequently Asked Questions On Commercial Vehicles
Q1. What is AIS-228 and what does it do?
Ans: AIS-228 is a newly approved retrofit standard that can cut particulate matter emissions from pre-BS6 trucks and buses by up to 90%, bringing them closer to BS6 emission levels.
Q2. Does the AIS-228 retrofit replace the need for the Parivartan scrappage scheme?
Ans: No, it offers an additional option alongside scrapping. Owners can now choose to retrofit an ageing vehicle instead of scrapping it under the Parivartan programme.
Q3. How many truck and bus owners have registered under the Parivartan scheme so far?
Ans: More than 1,300 truck and bus owners had registered under the scheme as of the latest update, with 53 scrapping centres now operational in the region.
Q4. What share of Delhi-NCR's PM2.5 emissions comes from trucks and buses?
Ans: Trucks and buses make up roughly 3% of Delhi-NCR's vehicle fleet but are responsible for about 36% of the region's PM2.5 emissions, according to ministry figures.
