Learn About Carbon Pollution From Power Plants
In 2009, EPA determined that greenhouse gas pollution threatens Americans' health and welfare by leading to long lasting changes in our climate that can have a range of negative effects on human health and the environment. Carbon dioxide (CO2) is the primary greenhouse gas pollutant, accounting for nearly three-quarters of global greenhouse gas emissions and 84% of U.S. greenhouse gas emissions.

The electric power sector accounted for 33% of U.S. total greenhouse gas emissions and 60% of U.S. stationary source greenhouse gas emissions in 2011.
Fossil fuel-fired power plants are the largest source of U.S. CO2 emissions. Fossil fuel-fired power plants use natural gas, petroleum, coal or any form of solid, liquid, or gaseous fuel derived from such material for the purpose of generating electricity.
Unchecked carbon pollution leads to long-lasting changes in our climate, such as:
- Rising global temperatures
- Rising sea level
- Changes in weather and precipitation patterns
- Changes in ecosystems, habitats and species diversity
These changes threaten America's health and welfare for current and future generations. Public health risks include:
- More heat waves and drought
- Worsening smog (also called ground-level ozone pollution)
- Increasing the intensity of extreme events, like hurricanes, extreme precipitation and flooding
- Increasing the range of ticks and mosquitoes, which can spread disease such as Lyme disease and West Nile virus
Our most vulnerable citizens, including children, older adults, people with heart or lung disease and people living in poverty may be most at risk from the health impacts of climate change.
On June 25, 2013, President Obama announced a series of executive actions to reduce carbon pollution, prepare the U.S. for the impacts of climate change and lead international efforts to address global climate change. As part of the Climate Action Plan, President Obama issued a Presidential Memorandum directing the EPA to work expeditiously to complete carbon pollution standards for the power sector. You can learn more about the President's Climate Action plan on the White House web site.
