EPA Proposes New Clean Air Act Standard

Limits C02 emissions on new power plants

The U.S. Environmental Protection Agency (EPA) today proposed Clean Air Act standards to cut carbon pollution from new power plants in order to combat climate change and improve public health. In addition, EPA has initiated broad-based outreach and direct engagement with state, tribal, and local governments, industry and labor leaders, non-profits, and others to establish carbon pollution standards for existing power plants and build on state efforts to move toward a cleaner power sector.

Under today’s proposal, new large natural gas-fired turbines would need to meet a limit of 1,000 pounds of CO2 per megawatt-hour, while new small natural gas-fired turbines would need to meet a limit of 1,100 pounds of CO2 per megawatt-hour. New coal-fired units would need to meet a limit of 1,100 pounds of CO2 per megawatt-hour, and would have the option to meet a somewhat tighter limit if they choose to average emissions over multiple years, giving those units additional operational flexibility.

Power plants are the largest concentrated source of emissions in the United States, together accounting for roughly one-third of all domestic greenhouse gas emissions. Currently, nearly a dozen states have already implemented or are implementing their own market-based programs to reduce carbon pollution. In addition, more than 25 states have set energy efficiency targets, and more than 35 have set renewable energy targets. While the United States has limits in place for arsenic, mercury and lead pollution that power plants can emit, currently, there are no national limits on the amount of carbon pollution new power plants can emit.
