Ask a Scientist: UCS Transportation Program Adds Equitable Mobility to its Portfolio

Union of Concerned Scientists

In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. Cars and trucks are a lot cleaner than when I was growing up. Transit agencies in Washington, D.C.,

Clean Air Act turns 50

Environment, Law, and History

Clean Air Act programs have lowered levels of six common pollutants — particles, ozone, lead, carbon monoxide, nitrogen dioxide and sulfur dioxide — as well as numerous toxic pollutants. The emissions reductions have led to dramatic improvements in the quality of the air that we breathe.

Greenhouse gas emission impact from peatland fires underestimated by 200%-300%, shows new study

Frontiers

When peatlands burn, the stored CO2 gets released into the atmosphere, together other GHGs such as carbon monoxide (CO) and methane (CH4). The accompanying smoke plumes contribute to air pollution, affecting wildlife and human health. Deforestation fires emissions.

There are many human-made sources of emissions, and on-road motor vehicles, such as cars, are a huge driving factor in air pollution. Motor vehicle exhaust is one big source of ground-level ozone or smog, fine particulate matter, carbon monoxide and nitrogen dioxide. Courtesy of Stephy Miehle/Unsplash. Gets You Outside.
