The American Lung Association (ALA) released its “State of the Air” report last week, and the organization found that air quality in U.S. cities has improved in the time period from 2012–2014. The ALA report specifically cites the increased air quality protections and emission reduction programs that first began popping up in the U.S. to improve air quality in the 1970s.
While overall air quality improved in the major cities studied in the report, the ALA did note that short periods of increased air particulate contamination existed in many areas. Furthermore, the ALA added that at least 166 million Americans are currently living in areas where the level of air contaminants exceeds safe limits.
The timing of this report is very important, as the group is hoping to use this information to convince the Trump administration not to repeal or otherwise weaken air quality standards enacted by the Obama administration.
