The EPA will propose new regulations Thursday designed to cut carbon dioxide from the nation's coal- and natural-gas-fired power plants. The EPA's long-awaited proposals come after SCOTUS put new constraints on the agency's authority.
The EPA's long-awaited proposals come after the Supreme Court put new constraints on the agency's authority to regulate carbon emissions from power plants last year and represents one of the highest-profile regulatory developments yet under President Joe Biden, who signed the U.S. up to achieve net-zero emissions by 2050.
"The proposed limits and guidelines would require ambitious reductions in carbon pollution based on proven and cost-effective control technologies that can be applied directly to power plants," said EPA Administrator Michael Regan. The EPA based its new standards on technologies such as carbon capture and sequestration, low-greenhouse-gas hydrogen co-firing, and natural gas co-firing. Co-firing involves the combustion of one fuel in conjunction with another to generate power.
The Supreme Court ruled that the EPA cannot employ generation shifting as the best system of emissions reduction, as the Obama-era CPP sought to do. Generation shifting generally means a"shift in electricity production from higher-emitting to lower-emitting producers," as the court defined it. Coal interests and some lawmakers, including Sen. Joe Manchin and many Republicans, have criticized the direction the EPA is taking its carbon emissions rules and argued it will drive further retirements of coal plants and further threaten grid reliability.
