What we're doing: Through science, advocacy, and the courts, we're defending existing clean air standards and closing policy loopholes that expose many Americans to air pollution.
Why: Air pollutants take a steep toll on human health. Clean air standards will save thousands of lives – especially in at-risk communities – and must be protected and enforced.
Protect Americans from smog and other major air pollutants
We're fighting to defend standards that limit smog, soot and other pollutants emitted by power plants that burn fossil fuels.
Trim pollutants from oil and gas development
We're defending and advancing policies that protect communities near oil and gas production facilities.
Map pollution with mobile sensors
Air pollution is harmful to our health. It's also invisible and hard to measure. With Google, we convened a team to map it – in detail nearly impossible before.
