Ambitious climate action to improve global air quality could save up to 1.32 million lives per year by 2040, according to a new study. The research, led by Cardiff University, shows how developing countries rely heavily on international cooperation to see these benefits, because much of their pollution originates outside their borders. The first-of-its-kind study analyzed these cross-border pollution “exchanges” for nearly every country—168 in total.
