Air pollution in Delhi, the capital of India, was found to be one of the most lethal of any city in the world in an August 2022 study of 7,000 world cities by the US-based Health Effects Institute. Air pollution in India is estimated to kill about 2 million people every year. India has the world's highest death rate from chronic respiratory diseases and asthma according to the World Health Organization. In Delhi, poor air quality has irreversibly damaged the lungs of 2.2 million children. During the COVID-19 pandemic lockdown in India, the air quality in Delhi significantly improved. India's Ministry of Earth Sciences published a research paper in October 2018 attributing almost 41% of air pollution to vehicular emissions, 21.5% to dust and 18% to industrial emissions. The director of the Centre for Science and Environment alleged that the Society of Indian Automobile Manufacturers was lobbying "against the report" because it was "inconvenient" to the automobile industry. The air quality index (AQI) in Delhi generally falls within the Satisfactory (51–100) and Moderate (101–200) ranges between March and September, and then drastically deteriorates to Poor (201–300), Severe (301–400), or Hazardous (401–500+) levels between October and February due to various factors including the burning of effigies during Vijayadashami, the bursting of firecrackers during Diwali, thermal power plants in the National Capital Region, stubble burning, road dust, vehicle pollution and cold weather. In November 2016, in an event known as the "Great Smog of Delhi", the air pollution spiked far beyond acceptable levels. The levels of PM2.5 and PM 10 particulate matter hit 999 micrograms per cubic meter, well above their respective 24-hour peak limits of 15 and 60 micrograms per cubic metre. According to Bloomberg, 1,670,000 people died due to polluted air in India in 2019. According to data released by the Ministry of Environment, Forest and Climate Change in 2022, the Air Quality Index in Delhi stood at over 200 for at least half the year. Animal agriculture also contributes to Delhi's pollution problem, as smog and other harmful particles have been produced by farmers burning their crops in other states since the 1980s. An initiative that is being considered to address air pollution is a 1,600 km long and 5 km wide green ecological corridor along the Aravalli Range from Gujarat to Delhi connecting to the Sivalik Hills range. This would involve the planting of 1.35 billion (135 crore) new native trees over 10 years to combat pollution. In December 2019, IIT Bombay, in partnership with the McKelvey School of Engineering of Washington University in St. Louis, launched the Aerosol and Air Quality Research Facility to study air pollution in India. The Delhi government announced in November 2021 that it would be shutting all schools and government offices for a week due to the severe air pollution. The government told the Supreme Court that it was confident and prepared for
