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.

Getting more zero- and low-emission vehicles on the road in Pennsylvania helps reduce harmful air pollutants, including nitrogen oxides, carbon monoxide, particulate matter, and volatile organic compounds. It also helps lower the level of carbon dioxide, one of the greenhouse gases heating up the climate, in the air.

Critically, and as we’ll discuss in greater depth shortly, hydrogen combustion (as opposed to its use in fuel cells) also leads to greater emissions of nitrogen oxides (NOx), a toxic group of pollutants regulated under the Clean Air Act. It is also a precursor to other pollutants, including ozone (a key component of smog).

By replacing older polluting engines and equipment with new technologies, funded projects remove nitrogen oxide, carbon monoxide, particulate matter, and hydrocarbon pollution from the air. Zero- and low-emission vehicles also lower carbon dioxide emissions, helping to lessen climate change.
