The Cost of Premature Birth from Preventable Air Pollution in California
Over 3,000 premature births in California could be avoided by reducing particulate matter pollution, saving $170 million each year.

Air pollution can have many serious effects on health, starting from the very first stages of life. Research has shown that air pollution can increase a mother's risk of premature birth, medically known as 'preterm birth' for infants born before 37 weeks of gestation.

Tracking California analyzed data to better understand the costs of preterm birth due to preventable particulate matter (PM) pollution. Our results provide better information on the role that preventable PM plays in preterm birth risks and on its economic impact in California.
