Delhi odd even: Delhi has faced severe air pollution and it needs to tackle it sooner rather than later. Taking a cue from Beijing will be the best possible way for the Arvind Kejriwal government. On November 2 this year, a text alert was sent to all mobile numbers issued in Beijing. Residents were warned of worsening air quality and that an orange alert — the second highest — had been declared. The orange alert means children and the elderly should stay indoors, certain factories would have to cut production and heavy vehicles would not be allowed to ply Beijing’s roads between November 4 and November 8, according to Indian Express report.

It has been learnt that the announcement was made two days in advance to allow the city to cope with an emergency action plan and if possible, hold the smog to lower levels than predicted. State-run media reported that after the orange alert ended November 8, air quality levels were better than expected. Data from the US Embassy in Beijing, which measures concentrations of PM 2.5 and the corresponding Air Quality Index (AQI), showed pollution levels peaked between November 5 and November 6 (160-210). According to Beijing’s air quality standards, an orange alert means the AQI will remain above 200 for three consecutive days.

The forecast and advance warning are crucial aspects.

On November 11, the Delhi government had called off the odd-even scheme. Transport Minister Kailash Gahlot had said the governments decision came in view of the directive by the National Green Tribunal, which ordered the withdrawal of all exemptions, including to two-wheeler riders and woman-only vehicles, under the odd-even scheme. The government is not ready “to compromise with the safety of women” after the NGT ordered that there should be no exemption to anyone expect emergency vehicles like ambulances and fire tenders, he said. The Delhi government had announced implementation of the odd-even scheme from November 13-17, given the high level of smog in the capital.

1. Under the policy, private vehicles are allowed to run based on the last digit of their licence plates.

This pattern will continue for 5 days.
