Carbon Pollution Standards

Carbon Pollution Standards

The U.S. Environmental Protection Agency (EPA) issued final rules in August 2015 to limit carbon pollution from existing and new power plants. Electric power generation accounts for 40 percent of U.S. carbon emissions, making it the largest source. 

Reducing power sector emissions is a key part of President Obama’s Climate Action Plan, which aims to reduce overall U.S. greenhouse gas emissions 17 percent below 2005 levels by 2020. In addition, the U.S. contribution to the upcoming international climate agreement in Paris sets an economy-wide target of reducing greenhouse gas emissions by 26-28 percent below 2005 levels by 2025.

Under the Clean Power Plan for existing power plants, each state has its own target (due to regional variation in generation mix and electricity consumption). Overall, the rule is designed to cut emissions 32 percent from 2005 emission levels by 2030.

EPA's “Carbon Pollution Standard for New Power Plants” finalizes a standard first proposed in March 2012 that was modified and proposed again in September 2013. States would apply the standards for new coal- and natural gas-fired plants (measured as tons of greenhouse gas emissions per megawatt-hour of elec­tricity produced) at each regulated plant.
