Air pollution is the contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide. Outdoorand indoor air pollution causes respiratory and other diseases and is an important source of morbidity and mortality. WHO data shows that nearly all of the global population (99%) breathes air that exceeds WHO guideline limits and contains high levels of pollutants, with low- and middle-income countries experiencing the highest exposure. Air quality is closely related to the earth's climate and ecosystem globally. Most of the drivers of air pollution(i.e. burning fossil fuels) are also sources of greenhouse gas emissions. Therefore, policies to reduce air pollution, offer a win-win strategy for both climate and health, reduce the burden of diseases associated with air pollution, as well as contribute to the mitigation of short-term and long-term climate change.
