New Delhi: With winds not strong enough to blow away the smog hanging over the city, Delhiites continued to be victims of severely poor air quality. However, while stubble burning in the neighbouring states has exacerbated the situation, Delhi seems to be failing in controlling locally generated pollutants and emissions. On Saturday, the Supreme Court made this point while noting that stubble burning did contribute to the capital’s murky air, it was not the sole reason for it.

According to data from Indian Institute of Tropical Meteorology (IITM), on Saturday, the city was largely a victim of its own pollution sources, with around 10% of the PM2.5 pollutants locally generated by biomass burning and 24% by vehicles. Other contributors were industries at 7.6%, construction at 3.5% and internal waste burning, 2.2 %.
