Vehicular Pollution

During post-monsoon and winter months, lower temperatures, lower mixing heights, inversion conditions and stagnant winds lead tothe trapping of the pollutants resulting in high pollution in the region

Vehicular emission is the top contributor to Delhi's pollution during winter season--more than stubble burning, road dust or bursting of fire crackers -- with over 50 per cent of pollution from local sources linked to city's fragmented transportation system, according to the Centre for Science and Environment (CSE). An estimated 1.1 million vehicles enter and exit Delhi daily, further worsening the air quality. The traffic caused from this vehicle influx intensifies pollution, particularly nitrogen oxides (NOx), which account for 81 per cent of NOx pollution in Delhi. According to data presented by the CSE, local pollution sources in Delhi account for 30.34 per cent of the city's air pollution (50.1 per cent of which is contributed through transportation), while 34.97 per cent originates from the neighbouring NCR districts and 27.94 per cent from other areas. Stubble burning contributes only 8.19 per cent to Delhi's pollution levels. These data points are based on the CSE's analysi

Environment Minister Gopal Rai on Saturday said the Delhi government will answer all questions raised by Lieutenant Governor Vinai Kumar Saxena on the "Red Light On, Gaadi Off" campaign and resubmit the file for his approval. Earlier in the day, Saxena returned the file to Chief Minister Arvind Kejriwal asking him to reconsider the campaign. He questioned the effectiveness of such an "ad-hoc" measure as the national capital reels under high air pollution. Addressing a press conference, Rai said, "We will give written answers to all queries raised by the LG and resubmit the file (for approval)... We hope that he will make a positive decision on the issue soon." Rai accused Saxena of doing politics over an issue concerning the lives of residents of Delhi. "The LG has returned the file, saying the Delhi government did not get a study conducted to ascertain the impact of the campaign over the last two years. We conducted the campaign in 2020 and 2021 after carefully studying all availa

The Delhi government will launch the "Red Light on Gaadi off" campaign again to curb vehicular pollution from October 28, Environment Minister Gopal Rai said on Friday. Under the campaign, first launched on October 16, 2020, to cut down vehicular pollution in the national capital, drivers are encouraged to switch off their vehicles while waiting for the traffic light to turn green. At a press conference, Rai said experts are of the view that pollution levels may increase in Delhi after Diwali if the wind direction changes. "The Delhi government is on alert. We are strictly implementing all the directions of the Commission for Air Quality Management. Chief Minister Arvind Kejriwal on Friday reviewed the implementation of the 15-point action plan to curb air pollution in winter," he said. Along with dust and biomass burning, vehicular emissions is one of the major contributors to Delhi's pollution generated locally, the environment minister said. "Therefore, the Delhi government has
