Despite adding six million more passenger cars, trucks, and SUVs to the roads over the last 10 years, California’s gasoline consumption has dropped over two billion gallons from its peak in 2005. Gasoline use per person has also fallen, from 445 gallons per year per person in 2005, to under 350 gallons per year per person in 2024.

The Environmental Protection Agency’s (EPA) Clean School Bus (CSB) Program was established by the Energy Policy Act of 2005 to help communities reduce pollution from older, higher polluting school buses. Despite past investments, thousands of older polluting school buses remain on the road. But lower climate emissions aren’t the only benefit.

Had the court ruled fully in favor of the EPA— or not taken the case at all —a much more meaningful dent in power plant carbon emissions would be within reach, while also delivering much greater reductions in other dangerous co-pollutants from burning fossil fuels such as particulate matter, mercury, nitrogen oxides and sulfur dioxide.

Nitrogen oxides, which can cause damage to the respiratory pathways as well as the burning of eyes and skin, are byproducts of high temperature combustion. Flaring, which is shown here, as well as venting, can be a significant source of both nitrogen oxides and greenhouse gas emissions such as methane.

Since 2005, shale gas development, also known as unconventional natural gas development (UNGD), has grown rapidly. 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.

Environmental Protection Agency methodologies to assign a dollar value to each ton of nitrogen oxide and sulfur dioxide reduced. Between 2005-2022, the last year of available data, 11,127,515 fewer tons of SOx and 1,317,335 fewer tons of NOx were emitted from Pennsylvania’s electric power sector, according to DEP data.
