  Air pollution is a major issue in Mumbai. According to the 2016 World Health Organization Global Urban Ambient Air Pollution Database, the annual average PM2.5 concentration in 2013 was 63 μg/m, which is 6.3 times higher than that recommended by the WHO Air Quality Guidelines for the annual mean PM2.5. The Central Pollution Control Board for the Government of India and the Consulate General of the United States, Mumbai monitor and publicly share real-time air quality data. 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 Mumbai, among other Indian cities.
