Clean Air Markets – Environmental Issues

EPA’s Clean Air Markets Programs address several environmental issues which are briefly described below with links to more information.

Acid Rain
Acid deposition, or acid rain as it is commonly known, occurs when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. Prevailing winds can transport these compounds hundreds of miles, across state lines and national borders. These compounds then fall to the earth in either dry form (such as gas and particles) or wet form (such as rain, snow, and fog). Visit EPA’s Acid Rain website for more information.

Climate Change
Over the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. The majority of greenhouse gases come from burning fossil fuels to produce energy, although deforestation, industrial processes, and some agricultural practices also emit gases into the atmosphere.  Visit EPA’s Climate Change: Basic Information page for more information on the causes of climate change and what you can do to make a difference.

Ground-Level Ozone (Smog)
Ground-level ozone, or smog, is air pollution that makes breathing more difficult, negatively effects health and ecosystems, and impairs visibility. Ground-level ozone is created when NOx reacts with other chemicals in the air, especially in the presence of strong sunlight. NOx can travel long distances before reacting to form ozone, creating regional problems instead of only affecting the local area where it is emitted. Visit EPA’s Ozone Pollution website for more information.
