Finally, some sense instead of hysteria. Vehicular pollution is responsible for only 6.6% of particulate matter in Delhi air, and out of that, cars’ share is only 22%, i.e. only 2% of the total.
Dust causes 52% of the particulate matter. Of course now the Environmentalists would say that ban all constriction in Delhi. Dust in Delhi has two sources-large non-paved areas, and the desert to its west- i.e. Southern Haryana and Rajasthan. Too much of Green covers means that the dust laden winds stay in Delhi, instead of blowing away. Solution is to fully pave all the open spaces in Delhi or grass-carpet them, and reduce tree cover and build more.
