The Air Resources Board estimates that between 2026 and 2040, the ACCII rules will eliminate 69,569 tons of nitrogen oxides and 4,469 tons of particulate matter (PM2.5) , leading to over 1,200 fewer cardiopulmonary deaths due to air pollution. . The impact of the new rules goes beyond just lowering carbon emissions.

California recently extended , for the second time, the operations of three gas plants to 2026. Most notable of these polluting emissions are nitrogen oxides (NOx). Even as some parts of the country transition away from fossil fuel infrastructure, the retirement of gas plants has become another driver of inequity.

gigawatts of capacity from gas plants are planned to go online from 2023 to 2026. But gas plants also release emissions of nitrogen oxides, more commonly referred to as NOx emissions, that contribute to smog and other pollutants. NOx emissions stick around locally, with major health consequences to nearby residents.

The EPA is getting ready to finalize a critical regulation limiting emissions of smog-forming nitrogen oxide (NO X ) and soot (or particulate matter, PM 2.5 ) from new heavy-duty trucks. This is the first time EPA has sought to limit emissions in over two decades, and it is long overdue.

PA Bulletin, page 2572 ) This facility is classified as a major facility for RACT purposes having the potential to emit greater than 100 tons per year of nitrogen oxide (NOx) and 50 tons per year of volatile organic compound (VOC) emissions.

But while greenhouse gas emissions may be reduced, a delivery fulfilled by a diesel-burning truck may lead to increases in emissions of smog-forming nitrogen oxides and lung-damaging particulate matter.
