Each year, 6.1 million lives are lost prematurely due to air pollution. Though most acutely and visibly hampering megacities of the developing world, air pollution is a growing public health emergency that affects almost all of us in our daily lives, whether or not we are aware of it. The Health Effects Institute estimates that only 5% of the global population are lucky enough to live in areas with air pollution levels below safe guidelines. Though recent studies suggest there may in fact be no risk-free level of air pollution.

Why is this number relevant to climate policy? Because one common culprit is responsible for the majority of both climate change and air pollution: fuel combustion. Burning coal, oil, natural gas, and biomass – for everyday uses ranging from electricity, heating, cooking, to transportation – releases hundreds of gases and particles, some of which disrupt the climate system or are harmful to human health, or both. Climate change could also worsen air quality in the future.

Decades of research have revealed that air pollution is associated with a wide range of diseases and disorders, including asthma, cancer, heart disease, stroke, and premature birth. There is also emerging evidence that pollution from coal combustion and motor vehicles can cause development delays, reduced IQ, and autism in children. The societal and economic costs of air pollution are multifold. There are costs to the affected individuals, to their families and to society in terms of direct medical costs, costs to healthcare systems, productivity losses, and lower economic growth (not to mention costs resulting from damages to ecosystems).

Yet almost none of these costs stemming from our fossil fuel reliance are included in the majority of cost-benefit analyses of climate mitigation strategies. A recent study estimates that the health co-benefits from air pollution reductions would outweigh the mitigation costs of staying below 2°C by 140–250% globally. Historical evidence paints a similar picture. The EPA estimates that the U.S. Clean Air Amendments cost $65bn to implement, but will have yielded a benefit of almost $2tn by 2020 in avoided health costs.
