Reducing air pollution from transportation, including toxic air pollutants, helps protect the health of Californians, reducing premature death, illness, hospital visits, health care costs, and school and work absenteeism, in addition to addressing a changing climate that is threatening the health and safety of Californians in unprecedented ways, and costing the State more than $16 billion a year from disasters like drought and wildfire.
