Primarily, these have focused on the 2007 EPA regulations, which were the first step in the phase-in of diesel engine standards meant to cut particulate emissions by more than 80 percent and smog-forming nitrogen oxides (NO X ) emissions by 90 percent.

These fees and programs were established with legislation in 2007 and then were extended until 2024 with the passage of Assembly Bill 8 in 2013 (hence the name, “AB 8 fees”). Now, Assembly Bill 241 (AB 241) would extend these fees and modernize the funding programs to make sure that public dollars are spent in common sense and equitable ways.

IRA clean energy investments also will protect public health by cutting key toxic air pollutants, such as nitrogen oxides and sulfur dioxide, by more than 50 percent by 2050, and drastically reduce fine particulate matter, which will save hundreds of billions of dollars in 2035 alone from avoided premature deaths.

Coal also emits other air pollution factors such as sulfur dioxide, nitrogen oxides and particulate matter… All this causes smog and soot which in turn cause asthma, cancers of all sorts, cardiovascular diseases… Which brings us to its health effects: coal is a mass murderer and is responsible for immense suffering.

Unlike other major air pollutants, ground-level ozone is not emitted directly into the air but is created by chemical reactions between nitrogen oxides and volatile organic compounds, meaning that ozone pollution is tied to sources that emit these precursor chemicals, such as heavy duty vehicles.
