Air Pollution

[op-ed snap] Clearing the air


From UPSC perspective, the following things are important :

Prelims level : Nothing much

Mains level : Delhi Air pollution


The odd-even scheme will make a comeback in Delhi four years after it was first implemented. 

Fighting pollution

  • Delhi Chief Minister announced that the road rationing scheme will be a part of a seven-point programme to combat pollution.
  • The scheme will be implemented when Delhi’s air is at its worst
    • post-festival pollution combines with
    • smog from stubble burning in Haryana, Punjab and Uttar Pradesh
    • particulate matter from tailpipes of vehicles
  • In the last three years, the government resorted to knee-jerk reactions which did very little to improve the city’s air quality. 

Odd-Even scheme

  • The road rationing scheme allows vehicles to ply on alternate days, depending on odd and even number plates. 
  • It was introduced in 2016 as a desperate measure after the Delhi High Court asked the state government to submit a time-bound plan. 
  • A fight between the Delhi government and NGT came in the way of its implementation in 2017. 
    • The NGT said that any relaxation would come in the way of improving the city’s air quality.
    • But the government wanted exemptions for two-wheelers. 
  • The government argued that Delhi’s public transport wasn’t equipped to handle the fallout of extending road-rationing to two-wheelers. 

Way ahead

  • The government has nearly two months to iron out glitches and sort out differences that could come in the way of smooth implementation of the plan. 
  • It needs to ensure that the city’s public transport system is able to meet the needs of commuters on days when their vehicles will be off the roads.


The odd-even scheme is not a magic bullet to clean up Delhi’s bad air. But the scheme is a part of a bouquet of pollution-control measures.
