The EPA has announced new, stricter limits on soot pollution, reducing the allowable limit for annual PM2.5 levels from 12 to 9 micrograms per cubic meter. This marks the first tightening of the rules since 2012, with the aim of preventing about 4,500 premature deaths a year by 2032 in the U.S. and reducing healthcare costs by about $46 billion. The new standards are expected to have a major impact on communities currently experiencing the worst pollution, particularly those of color, but are still above the World Health Organization's recommended limit. The decision comes after a review under the Biden administration, with public health experts emphasizing the ongoing dangers of fine particle pollution and its deadly effects.
