Vehicular emissions major cause of Delhi's winter pollution, says CSE
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.
