The study reports case-specific monetary estimates for preterm birth, low birth weight, asthma, autism spectrum disorder, attention-deficit/hyperactivity disorder, and IQ reduction in children -- which scientific evidence shows are among the known or likely health consequences of prenatal and early childhood exposure to air pollution, 80 percent of which is attributable to burning of coal, oil, diesel and gas.

The researchers conducted a systematic review of the scientific literature published between January 1, 2000 and June 30, 2018 to identify relevant economic costs for these six adverse health outcomes in children. In all, they reviewed 1,065 papers from the U.S. and U.K. and identified 12 most relevant papers. They separately identified estimates of the lost lifetime earnings associated with the loss of a single IQ point.
