Pollution Control as Climate Policy

The Biden administration is slowly grinding away at an important regulatory task: reconsidering the air quality standards for particulates and ozone. Setting those standards is an arduous and time-consuming process, requiring consideration of reams of technical data. For instance, a preliminary staff report on fine particulates (PM2.5) is over 600 pages long. When the process is done, the result will not only be better protection of public health. It will also be a reduction in emissions of carbon dioxide and other global warming agents.
Quick legal background: The Clean Air Act requires EPA to set national ambient air quality standards or NAAQS (pronounced "knacks"). They are supposed to be set at a level that, "allowing an adequate margin of safety, are requisite to protect the public health." They're supposed to be revised every five years based on new science, though EPA has tended to fall beyond schedule. The Trump administration decided that the existing standards are just fine, but Biden directed EPA to reconsider.
It seems pretty clear that the current PM2.5 standard is too high. Averaged over a year, the current standard limits emissions to …
