Air pollution is a major public health issue that causes millions of premature deaths annually. In Chennai, India, with a population of over 8 million people, there are only 3 government air quality monitors, providing insufficient data on pollution levels. Hospitals and healthcare facilities have an important role to play in addressing air pollution through education, advocacy, and monitoring of local air quality near their facilities, as demonstrated by a case study of the Huma Lung Foundation in Chennai. The Foundation installed air quality monitors at their hospital to obtain better data and raise awareness of this important issue among patients, staff, and the public.
