The transportation sector accounts for 50% of U.S. urban air pollution. Mobile sources (cars, trucks, and buses) also are significant contributors to air toxics – pollutants known or suspected to cause cancer or other serious environmental effects, according to the Alliance to Save Energy's report, The Drive to Efficient Transportation, May 2005. Air toxics and criteria pollutants can aggravate asthma, bronchitis, and other breathing problems, especially in combination with other environmental factors.
Transportation-related pollutants contribute to unhealthy air quality and, therefore, can aggravate asthma, bronchitis, and other breathing problems, either alone or in combination with other environmental factors.
The oil and gas and automotive industries have worked with EPA since 2004 to meet new vehicle and fuel standards that reduce emissions of criteria pollutants and VOCs. And the recently passed Energy Independence and Security Act of 2007 will result in a reduction of an estimated 1.2 billion tons of greenhouse gas emissions through 2022.
But consumers have the power to do much more. We can improve the air we breathe and help ensure our respiratory health by properly maintaining our vehicles, driving sensibly, and choosing more fuel-efficient new and used vehicles and, when possible, using public transit, carpooling, biking, walking, and telecommuting.
