The cut in vehicular emission due to rolling out of the odd-even scheme has resulted “definitive decline” in levels of PM2.5 pollutants, Delhi Government said on Tuesday while claiming success of the restrictions unveiled on January 1.
The Government said data of pollutants collected from over 55 locations showed a clear trend of improving air quality in several areas across the city and that there has been a “positive impact” of the odd-even scheme.
“According to the scientists of the Delhi Pollution Control Committee (DPCC), 80 per cent of PM 2.5 air pollution is caused by vehicular traffic and reduction in its levels, even in outer areas of Delhi shows that reduction of four wheeled vehicles on roads since the New Year Day is having a positive impact,” the government said in a statement.
However, a report by IIT Kanpur had said vehicular pollutions contribute to around 25 per cent of PM 2.5 concentrations during winters which comes down to 9 per cent during summers.
