AQLI: new data reveals little progress globally in reducing air pollution over the last two decades

Green Car Congress

Particulate air pollution continues to cut global life expectancy by nearly two years as progress in some countries counterbalances worsening air quality in others, according to the Air Quality Life Index (AQLI). High pollution across the entirety of Bangladesh makes it the most polluted country in the world.

Yet, aerosol emissions from Europe, the United States, and China are declining, while aerosol emissions from India and Africa are increasing. This work is part of a larger $1.5-million For example, their models show that aerosol emissions from Western Europe have 14 times the global cooling effect that aerosol emissions from India do.

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. New research led by the University of Washington (UW) is the first to measure this phenomenon’s effect over years and at a regional scale. Michael Diamond/University of Washington.
