Virtue Signalling Doesn’t Control Pollution

Public outrage has muted Delhi’s drive to push out old cars. Bigger problem is that clean air policies are fashioned without scientific insight or robust data. Some actually hurt the environment

Public backlash has forced Delhi govt to walk back from its initiative to impound ‘end of life’ vehicles. But before this, the sudden outrage over the directive to stop refuelling diesel vehicles older than 10 years and petrol vehicles older than 15 years was somewhat amusing. Many seemed to believe this was a new crackdown.

But these vehicles were banned in Delhi nearly seven years ago, on Oct 30, 2018, when govt began enforcing a Supreme Court backed order that prohibits such vehicles not just from operating, but even from being parked or present in the city. So, the fuel denial directive was merely an attempt to enforce an old order using a new method.

In fact, law-abiding citizens have been selling their older vehicles ever since the 2018 law. I sold my well-maintained 10 years old Bharat Stage IV diesel car (barely run for 100,000 km) in 2022. It went to a tour operator in Punjab at a bargain price so generous that he still sends me Diwali sweets.

Over the past seven years, lakhs of Delhiites have sold their vehicles to comply with the ban. Of course, the majority of these vehicles have not gone to scrap yards as intended; instead, they’ve been relocated to other parts of the country, polluting their environments instead.

So, why did Delhi govt decide to enforce the refuelling restriction seven years after banning these vehicles? Did the Commission for Air Quality Management have data showing that the original ban had been ineffective? No. There entire air quality action plan being enforced by Delhi govt and agencies like CAQM is bereft of data. There is no evidence showing the impact of vehicle ban on air quality, or even tracking the enforcement of the ban itself.

There is no formal vehicle deregistration system in Delhi. In effect, end-of-life vehicles are permanently technically ‘registered’ with the Regional Transport Office. Owners are expected to voluntarily deregister their vehicles – a process so tedious that few attempt it. This bureaucratic blind spot means govt has no reliable data on how many vehicles remain on Delhi’s roads, let alone how much pollution they continue to cause.

CAQM’s decision to block fuel sales, therefore, was not driven by scientific insight or robust data. Delhi has spent years creating the illusion of action without building the capacity to measure impact. Despite the relentless headlines on its air pollution, there is no data showing whether banning vehicles or halting construction during winters has improved air quality. We’re acting blindfolded, hoping that symbolic policies will solve real problems.

That brings us to the real question: does banning 10-year-old diesel and 15-year-old petrol vehicles help? Not much. Vehicles contribute less than 10% of Delhi’s PM2.5 emissions. Of that, the majority comes from two- and three-wheelers. But banning two-wheelers is a political hot potato and therefore difficult to enforce. That means cars (which contribute less than 5% to Delhi’s PM2.5 problem) are the main focus of the ban, even though the impact of banning cars on air quality would be minimal.

This is exactly why the much-hyped odd-even vehicle rationing scheme failed. It ignored the science of air pollution and tried to project political will through traffic gimmicks. Banning cars based on age and denying them fuel is another version of the same performative theatre.

Such policies do more harm than good to the environment. Prematurely disposing of vehicles, pushing people to buy new ones, boosts automobile sales and adds more vehicles to the road. In addition, every new vehicle carries a hidden environmental cost in terms of emissions from raw materials, manufacturing and logistics.

Rather than fixing arbitrary age limits, a sensible vehicle retirement policy would be based on fitness. Around the world, vehicles are allowed to operate as long as they pass periodic fitness checks, including emissions testing. A 15-year-old car that is well-maintained and meets pollution standards is less harmful than a new one, if we consider the environmental impact of a vehicle’s full life cycle.

But the problem is that India lacks the necessary infra to make this happen. There’s no robust inspection and certification system, no reliable pollution testing, and no systematic registration or deregistration process for vehicles. Nor do we have an effective network of end-of-life vehicle collection and recycling centres. If we’re serious about reducing vehicular pollution, we must invest in a credible and modern vehicle lifecycle management system.

To be clear, banning polluting vehicles is a good idea. Old, polluting vehicles must be phased out. But they must be banned through a structured, evidence-based, and environmentally sound policy regime, not ad hoc decisions. In the absence of systems, such bans serve more as virtue signalling than pollution control.

The air will not get cleaner because you make life harder for car owners. It will get cleaner when you treat clean air not as a slogan, but as a system – one that needs long-term, scientific, and institutional investment.
