Can Delhi’s desperate measures to clean up its air really work?

Laya Maheshwari says the traffic restrictions, fuel requirement and curbs on car sales unveiled won’t be effective if enforcement is not thought through and is consequently lax

Every year, India stages a grand military parade on Republic Day, January 26. This year, the chief guest was US President Barack Obama, who spent three days in New Delhi and held numerous meetings – resulting in announcements of new joint projects, such as those to improve the air quality in Indian cities. It was about time: Obama’s visit to India’s capital could have shortened his lifespan by six hours, according to David Spiegelhalter, a statistician at the University of Cambridge.

Fast forward to the present, and the situation seems to have become more shambolic. It is old hat that New Delhi is now the world’s most polluted city. The World Health Organisation accords India with the dubious distinction of being home to 13 of the top 20 polluted cities globally.

In the first week of December, around the time Beijing was suffering from the first of its recent terrible bouts of smog, PM2.5 levels (very fine particulate matter) in Delhi were around 1½ times worse. The Delhi High Court stated that being in the city was akin to “living in a gas chamber”.

Beijing has undoubtedly been successful in reducing congestion and air pollution by controlling car numbers, but whether Delhi can replicate that success is up in the air
The authorities responded with multiple reforms. Two coal-based plants in the city’s vicinity are to be shut down. The frequency of metro trains will be increased. All vehicles have to comply with Euro IV emission standards by 2017. And, in a leaf straight out of Beijing’s playbook, from January 1, the number of cars allowed on roads will be halved depending on their licence plates: odd-numbered cars for odd dates and so on.

The last move – even though it’s meant as a 15-day pilot project – has evoked the most scepticism and, in some cases, outrage. Beijing has undoubtedly been successful in reducing congestion and air pollution by controlling car numbers, but whether Delhi can replicate that success is up in the air.

First, Delhi’s experience may mirror Mexico instead of Beijing, where the introduction of similar moves led many people to buy a second, cheaper (and more polluting) car with a different licence plate. Second, the control period is to last from 8am-8pm, which leaves the door open for people to get round the curfews and thus increase congestion in the process, as in Bogota. Third, the monitoring mechanism for this rule has yet to be satisfactorily articulated.
