Earlier this month, the Environmental Protection Agency’s (EPA) Clean Air Scientific Advisory Committee (CASAC) released a draft set of recommendations calling on the EPA to tighten its current standard for ground-level ozone pollution to protect public health. But will the EPA follow CASAC’s recommendations?

California’s leadership on reducing truck pollution has been on full display the past few years, passing critical regulations requiring 90 percent reduction in smog-forming nitrogen oxide (NO X ) emissions from diesel trucks and requiring manufacturers sell an increasing share of electric trucks to move away from fossil fuels altogether.

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.

In 2021 alone, the plants slated for retirement emitted more than 28,000 tonnes of nitrogen oxides (NO x ), 32,000 tonnes of sulfur dioxide (SO 2 ), and 51 million tonnes of carbon dioxide (CO 2 ), according to EIA data. NO x also contributes to the formation of ozone (or “smog”), another toxic pollutant. micrometers or less.

But with the recent influx of government incentives for hydrogen production, new and improving production and storage technologies, and greater political will than ever before, H 2 ’s reputation is gaining favor. It is also a precursor to other pollutants, including ozone (a key component of smog).

Nuclear energy has very low NOx (nitrogen oxides), SO2 (sulphur dioxide), PM (particulate matter) and NMVOC (non-methane volatile organic compounds) emissions. The same is true for freshwater and marine eco-toxicity; ozone depletion and POCP (photochemical oxidant creation potential).
