The World has Passed "Peak Air Pollution"

Global emissions of local air pollutants have probably passed their peak.

The chart shows estimates of global emissions of pollutants such as sulphur dioxide (which causes acid rain), nitrogen oxides, and black and organic carbon.

These pollutants are harmful to human health and can also damage ecosystems.

It looks like emissions have peaked for almost all of these pollutants. Global air pollution is now falling, and we can save many lives by accelerating this decline.

The exception is ammonia, which is mainly produced by agriculture. Its emissions are still rising.

These estimates come from the Community Emissions Data System (CEDS).
