According to an analysis by Michael Greenstone(9.24.15), gains in life expectancy due to the improvement in air quality since 1970 have been as high as 5.2 years in some communities. “More than 200 million people currently live in places monitored for particulates in 1970 and today. On average, these people can expect to live an additional 1.6 years, for a total gain of more than 336 million life-years. Not all of these benefits came from Clean Air Act regulations. Other factors include local regulations and the shifting of relatively dirty industries abroad. But the Clean Air Act was a primary cause.”
