The odd-even scheme in Delhi is about to make a comeback. In Delhi, the air quality is in the `Severe` category as per the Central Pollution Control Board. To tackle the Delhi air pollution, Delhi Environment Minister Gopal Rai on November 06 announced the implementation of the Odd-Even scheme. The Odd-Even scheme will be applicable for one week from 13th to 20th November. Cars whose number plates end with odd numbers – 1, 3, 5, 7 and 9 – will be allowed to ply on odd-numbered dates. On the other hand, vehicles whose number plates end with even numbers – 0, 2, 4, 6 and 8 – will be allowed to ply on even-numbered dates. Stubble burning in the neighbouring states of Punjab and Haryana is credited for creating smog in Delhi.
