The U.S. Environmental Protection Agency (EPA) classifies diesel emissions as a “likely carcinogen.” Diesel emissions are estimated to be responsible for 70 percent of the cancer risk arising from air pollution, according to the California Air Resources Board. Dangers from diesel exhaust can range from respiratory illnesses including asthma and bronchitis to lung cancer and heart disease.
