State Air Regulations Can Go Above and Beyond National Standards 

State and local regulators can and should work to reduce particulate matter, ozone, and NOx emissions even when national standards are met. 

States and local air quality regulators have the legal authority to set particulate matter (PM), ozone, and nitrogen oxides (NOx) emissions standards and adopt regulations for these pollutants when they are already in attainment of the national ambient air quality standards (NAAQS) set by the U.S. Environmental Protection Agency (EPA) under the federal Clean Air …

Not Just About the Climate

The benefits of the energy transition transcend climate.

The main reason to control carbon is to protect the climate. But cleaning up the energy system has plenty of other benefits.

Air Quality Watchdog Agrees to Get Tougher on Refineries

Los Angeles' coastal bike path passes several large-scale energy infrastructure projects, including the Chevron Refinery in El Segundo, CA.

There’s a favorable settlement in the case brought by Earthjustice on behalf of EYCEJ with help from UCLA law students.

Last year, the South Coast Air Quality Management District was accused of not properly enforcing a state law that requires petroleum refineries to install air-quality monitoring systems around their perimeter. Essentially, the air quality watchdog exempted smaller refineries from having to follow the rules. Now, the SCAQMD has agreed to reverse course and move to …

Evidence is mounting that air pollution regulation is an effective way of reducing  health disparities between disadvantaged communities and the population as a whole. The basic reason is simple: Air pollution is the biggest environmental threat to poor communities and communities of color.  As the American Lung Association has said: “The burden of air pollution …
