Delhi’s latest electric vehicle proposal makes one thing clear: when policymakers run out of ideas to make cleaner technology attractive, they reach for taxes. The Delhi government is considering extending its green cess to petrol and CNG vehicles, on top of higher diesel levies, explicitly to make conventional cars more expensive and electric vehicles seem relatively cheaper. That is not climate leadership.
It is fiscal coercion dressed up as environmental policy. The premise is simple: make conventional vehicles more expensive and consumers will switch. But that assumes EV adoption is being delayed by attitude, not access. For many buyers, petrol and CNG vehicles remain the rational choice because they are cheaper upfront, easier to refuel, and more reliable for daily use, advantages that taxes do nothing to erase. Delhi already offers some of India’s most generous EV incentives: zero road tax, waived registration fees, and purchase subsidies of Rs 5,000 per kilowatt-hour.
Yet electric vehicles still account for only about 12 -14 per cent of new registrations. If subsidies alone have not delivered mass adoption, a 1-2 per cent cess on conventional vehicles is unlikely to do so either. For middle-income households buying two-wheelers or small cars, this tax is not a behavioural nudge, it is a price shock. For commercial drivers, delivery fleets, and small businesses, this shift functions less as an incentive and more as a penalty. EVs remain an impractical option for many operators: charging infrastructure is limited to few urban corridors, electricity supply is unreliable in large parts of the country, and resale markets for electric vehicles are still immature.
Raising the cost of petrol vehicles does nothing to address these structural gaps, it simply increases operating costs for those who have no viable alternative. Global experience points in a different direction. In countries where EV adoption has accelerated, such as Sweden, Norway, and Finland, the transition followed a sequence: build strong charging networks, ensure availability of vehicles across price segments, foster competition among manufacturers, and only then phase in penalties on high emission vehicles. Consumers were given a proper exit route before the door was closed. Delhi risks doing the opposite.
By leaning heavily on disincentives before the ecosystem is ready, it turns EV adoption into a forced decision rather than a rational one. This approach may raise revenue, the government estimates up to Rs 300 crore annually from levies on older vehicles, but revenue generation should not b e confused with environmental success. There is also a broader consumer-choice concern. When governments rely on taxation to engineer behaviour, they erode trust. Mobility is not a luxury; it underpins work, education, and daily life. Policies that treat vehicle ownership as a moral failing to be punished are more likely to provoke backlash than buy-in.
If Delhi is serious about cleaner air and higher EV uptake, it should prioritize rapid rollout of neighbourhood, charging infrastructure, technology neutral rules, realistic financing options and clear long-term signals to manufacturers and consumers. Electric vehicles will succeed when they are the better option, not when alternatives are made artificially worse. A green transition that depends on penalties is not a sustainable policy. It is simply an expensive way to delay the real work.
