India has 9 of the 10 most polluted cities in the world. As per a study based on 2016 data, at least 140 million people in India breathe air that is 10 times or more over the WHO safe limit. Air pollution contributes to the premature deaths of 2 million Indians every year.
Emissions come from vehicles and industry, whereas in rural areas, much of the pollution stems from biomass burning for cooking and keeping warm. In autumn and spring months, large scale crop residue burning in agriculture fields – a cheaper alternative to mechanical tilling – is a major source of smoke, smog and particulate pollution.
