Dear Administrator Regan, 

We are diverse non-federal leaders of U.S. local governments, businesses, investors, and faith, health, academic, and cultural institutions that have declared themselves to be “All In” on climate and are championing an all-of-society effort to reduce pollution. We have pledged to place climate considerations at the core of our own institutions and to support robust climate policies and investments at the national and local levels.
We write to express our thanks for the EPA’s renewed federal climate leadership and our support for your use of Clean Air Act authority in recently proposed standards to curtail emissions of greenhouse gasses (GHGs) and other pollutants harmful to human health from power plants. In order to fully leverage the further cost-reducing investments of recently passed legislation, maximize the benefits of these standards, and ensure we can harness further action by our institutions to meet our climate goals, we strongly urge the EPA to quickly finalize the most ambitious possible standards.

Recent Congressional and Administration investments in America, including the Inflation Reduction Act (IRA), the Infrastructure Investment and Jobs Act (IIJA), and the CHIPS and Science Act are allowing the U.S. to accelerate decarbonization at a rate more consistent with the U.S.’ ambitious and necessary goal of halving our climate pollution by 2030.
The power sector accounts for 25% of U.S. carbon emissions; according to the EPA, the proposed standards will result in $85 billion in net climate and health benefits and prevent 1,300 premature deaths and over 300,000 asthma attacks by 2030. 

Preliminary analysis from America Is All In and the University of Maryland's Center for Global Sustainability indicates that new regulations of this type—when combined with other actions from the federal government, states, cities, and others—can help cut power sector emissions by over 70% by 2030 from 2005 levels.

We applaud the EPA for taking important steps to adopt emissions standards for power plants, and we urge you to finalize ambitious national standards and build upon the significant progress our country has achieved in the past two years to combat the climate crisis and protect public health. We must all do our parts and pursue an all-of-society pathway to solve the climate crisis and secure a healthy, prosperous, equitable, and sustainable future for all. 

Sincerely,
