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.
