Examples are benzene, hydrofluoric acid, particulate matter, sulfur dioxide, nitrogen oxides, and many, many other toxic pollutants. In 2022, the transportation sector was responsible for 28 percent of global warming pollution in the country. Refining uses many risky industrial processes. See the pie charts below.

million in 2022 Alternative Fuels Incentive Grant funding to help municipalities, schools, and businesses around the state switch to clean transportation and improve air quality in their communities. It also helps lower the level of carbon dioxide, one of the greenhouse gases heating up the climate, in the air.

DEP hopes to get the proposed regulation to the Environmental Quality Board for action during the first quarter of 2022. Transportation generates 47 percent of nitrogen oxide and 21 percent of carbon dioxide emissions in Pennsylvania. There is no ban on traditional internal combustion engine vehicles.

Air Pollution Air pollutants such as carbon monoxide (CO), hydrogen sulfide (H2S), nitrogen oxides (NOx), particulate matter (PM), and volatile organic compounds (VOCs) are released from various stages of shale gas development. NOx and VOCs mix in the presence of sunlight to form ground level ozone (smog).
