Delhi's Refuelling Ban on Older Vehicles: Simple Policy, Imprecise Impact
Delhi's policy to ban refuelling for petrol vehicles older than 15 years and diesel vehicles older than 10 years, effective July 1, 2025, aims to curb air pollution. However, the policy is imprecise as vehicle age is a poor proxy for actual emissions without fitness checks. Implementation faces challenges with ANPR systems, staff training, and drivers bypassing the ban. Analysis shows only 8% of Delhi's vehicle fleet (7.5 lakh vehicles) is covered, potentially reducing PM2.5 emissions by only 8%. The article suggests learning from cities like Beijing and Tokyo, advocating for scrappage incentives, retrofits, annual conditional renewals, public engagement, and regional enforcement to achieve cleaner air.
Key Points
- Delhi's policy banning refuelling for older vehicles is a simple approach to air pollution but lacks precision as age is an imperfect proxy for emissions.
- Implementation challenges include inaccurate ANPR systems, untrained staff, and drivers circumventing the ban.
- The policy is projected to cover only 8% of Delhi's vehicle fleet and reduce PM2.5 emissions by approximately 8% if fully enforced.
- Effective solutions require a multi-faceted approach, including scrappage incentives, retrofitting options, public engagement, and regional enforcement across NCR.
