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.
