India is home to 14 of the world’s 30 most polluted cities, according to the World Health Organization (WHO)…
Delhi, its capital, regularly suffers winter air pollution levels of harmful particulate matter exceeding 700 mcg (micrograms)/m³, when the amount hazardous to human health is estimated to be 300 mcg. Delhi’s air pollution is the equivalent of smoking cigarettes a day resulting in a reported 6.3 years shortening of life expectancy.
In November 2017, Delhi’s air pollution levels spiked to 40 times WHO safety limits causing a major public health emergency in which schools were shut, foreign diplomats voiced fears that the city could become a “non-family” posting and cricket players in the test match between India and Sri Lanka resorted to using oxygen cylinders.

Delhi is home to 25 million people and major industries including banking, electronics and textiles. As a result, the city is experiencing a construction boom and major traffic congestion, all of which have exacerbated its air pollution problems.

Industry is said to account for 13 percent of Delhi’s air pollution. At critical levels, the authorities temporarily close the 705 MW Badarpur coal power plant. Unreliable power supplies or lack of access to the grid encourage large numbers of city dwellers to rely on diesel generators or kerosene lamps.
