The Centre's proposed policy to raise road tax on vehicles of a certain age from April 1 next year has the potential to renew a big part of India's vehicular fleet, reducing air pollution, raising fuel efficiency, and improving safety standards. It has taken the government years to finalise a tax on clunkers proposal, under which commercial transport vehicles will have to pay 10%-25% extra on road tax after eight years when renewing the fitness certificate, and, similarly, personal vehicles after 15 years; public transport is given concessions, while hybrids, electrics and farm vehicles are exempt. A higher tax in the most polluted cities, and on diesel engines is also on the cards. States, which enforce motor vehicles law, now have to weigh in on the proposed changes. Unlike similar programmes, such as the post-2008 recession CARS rebate plan in the U.S., India's scheme relies on penal taxation to persuade owners to scrap their old vehicles, with no cash-for-trade-in arrangement. For this approach to work efficiently, the additional tax proposed should exceed the resale value of the polluting motor, making its disposal more attractive, with enough safeguards to ensure that it is indeed scrapped and recycled under a monitored system. Equity features can be built into the scheme, offering a discount to income-vetted marginal operators such as autorickshaw drivers, on the lines of the 2009 stimulus given under the JNNURM scheme for buses. This should ideally be part of a green post-pandemic recovery plan, with an emphasis on electric vehicles.
