India, Aug. 14 -- The Supreme Court's decision on Tuesday to halt coercive action against owners of so-called end-of-life vehicles (ELVs) is more than just a procedural breather: It's a much-needed shift away from an unscientific, punitive approach that has bothered motorists for nearly a decade. The court has agreed to revisit its own 2018 order, which upheld the National Green Tribunal's 2014 directive banning diesel vehicles over 10 years old and petrol vehicles over 15 from the roads in the National Capital Region. In doing so, it has given space to discuss a valid argument: Emissions, rather than age, should be the yardstick of a vehicle's roadworthiness. On paper, the logic of the original ban appeared to be straightforward - older vehicles are presumed to pollute more. But such a presumption is a poor substitute for scientific rigour. There is no data-based evidence proving that every diesel vehicle over 10 years old is uniformly more polluting than a newer one. In fact, many such vehicles have low annual mileage, are well maintained, and meet pollution under control (PUC) norms. A vintage car that is taken out a few times a year may be cleaner over its lifetime than a modern SUV driven daily through Delhi's gridlock. The age-based ban is a blunt approach - easy to enforce, but scientifically questionable. The broader point is that Delhi's pollution crisis will not be solved through piecemeal measures. Targeting motorists while leaving far more damaging sources - industrial emissions, construction dust, biomass burning - largely untouched is selective enforcement. Such bans also disproportionately affect lower- and middle-income citizens for whom replacing a vehicle is a financial burden. They also ignore the environmental cost of scrapping and manufacturing - processes that consume vast energy resources. If the aim is cleaner air, the route must be a comprehensive, sector-wide strategy that marries technology with policy. Real-world emissions monitoring, expansion of clean public transport, mandatory retrofitting of high emitters, and investment in walkable and cyclable infrastructure must form the core. The role of the State is to create systems that are proactive, consistent, and rooted in science. The Supreme Court has now opened the door to establishing a more rational framework - one that focuses on pollution vehicles, not their birthdays. If the government can seize this moment to craft a broad-spectrum, evidence-based plan, Delhi could finally take a step towards solving its air crisis....
