FACT SHEET Final ACE Rule - CO2 Emissions Trends On Wednesday, June 19, 2019, EPA issued the Affordable Clean Energy rule (ACE), an effort to provide existing coal-fired electric utility generating units, or EGUs, with achievable and realistic standards for reducing greenhouse gas (GHG) emissions. This action was finalized in conjunction with two related, but separate and distinct rulemakings: o The repeal of the Clean Power Plan (CPP). o Revised implementing regulations for ACE, ongoing emission guidelines for existing sources, and all future emission guidelines issued under the authority of Clean Air Act (CAA) section 111(d). ACE will provide states with new emission guidelines that will inform the states' development of standards of performance to reduce carbon dioxide (CO2) emissions from existing coal-fired EGUs consistent with EPA's role as defined in the CAA. C02 EMISSIONS STEADILY DECLINING EPA projects that, compared to a no-CPP baseline, the ACE rule will reduce carbon dioxide (CO2) emissions in 2030 by about 11 million short tons, resulting in combined domestic climate benefits and ancillary health co-benefits of $570 million to $1.3 billion at a 3 percent discount rate, and $470 million to $1.1 billion at a 7 percent discount rate. ACE, combined with emission reductions expected from industry trends, will reduce CO2 emissions from the electric sector by as much as 35 percent below 2005 levels in 2030. CO2 emissions in the power sector have steadily declined in recent years due to a range of factors including: market forces, technology improvements, and regulatory and other policy changes. As a result, the industry has increased the use of natural gas and renewable energy sources. These trends have resulted in CO2 emission reductions even as the U.S. has sustained economic growth and job gains across the economyand this has all happened without the CPP ever going into effect, due to the Supreme Court's unprecedented stay of that rule in February 2016. The ACE rule will continue this trend. 1 ------- GDP Population Electricity Generation ... r-i^_icity C02 Emissions icity S02 + NOx -100% L/l ID O O 00 CT> O O O O O O O O fMfMfMfMfMfMfMfMfMfM O O CM (N **** The power sector emitted roughly 1.9 billion tons of CO2 in 2017, compared to 2.6 billion tons in 2005a 28 percent decrease.1 o Table 1 in the appendix to this fact sheet provides state-level CO2 emissions data for 2005 and 2017 as well as the state-level percentage of generation by fuel type for 2017.2 Approximately 600 coal-fired electric generating units at 300 facilities could be covered by this rule. The U.S. leads the world in reducing CO2 emissions. The Energy Information Administration (EIA) found that U.S. energy-related CO2 emissions fell by 14 percent between 2005 to 2017, with coal-related CO2 emissions down 39 percent over that period. During that time, global energy-related CO2 emissions rose by 21 percent.
