The Climate Pollution Standard and Community Investment Act of 2025 amends the Clean Air Act to establish a comprehensive national program requiring major pollution sources—including power plants, fuel producers, industrial facilities, and natural gas distributors—to reduce greenhouse gas emissions with a goal of achieving net-zero emissions by 2050. The bill creates a cap-and-trade system where covered entities must reduce emissions by 5 percent starting in 2027, followed by mandatory 2 percent annual reductions, with penalties of three times the auction price for non-compliance; the EPA will conduct quarterly allowance auctions beginning in March 2027 at a minimum price of $15 per ton of carbon dioxide equivalent. Revenue from allowance auctions and sales funds multiple programs including rebates and direct assistance for low-income households (50 percent of certain revenues), worker assistance for displaced employees, community adjustment payments to affected local governments, and grants for clean energy innovation and disadvantaged community projects, with the bill also establishing an Office of Energy and Economic Transition to coordinate federal support and an advisory committee to represent workers, communities, and industry throughout the transition process. Implementation requires the EPA to complete detailed regulations within 24 months and establish the trading framework by 2027, affecting millions of American workers and households while reshaping energy and industrial sectors across the economy.
