On August 21, the Environmental Protection Agency (EPA) proposed a new rule to reduce greenhouse gas (GHG) emissions from existing coal-fired electric utility generating units and power plants across the country. The Affordable Clean Energy (ACE) Rule would replace the 2015 Clean Power Plan (CPP) Rule. On August 24, the EPA and National Highway Traffic Safety Administration (NHTSA) issued a notice of proposed rulemaking to amend Corporate Average Fuel Economy (CAFE) and tailpipe carbon dioxide emissions standards for passenger cars and light trucks and establish new standards for model years 2021 through 2026.
Representative Carlos Curbelo (R-FL-26) introduced the first Republican carbon pricing bill in nearly a decade on July 23. The proposal, called the MARKET CHOICE Act (H.R. 6463), seeks to reduce greenhouse gas emissions by imposing a federal tax on carbon, and to use the revenue to fund infrastructure modernization. It would also impose a rolling, performance-based moratorium on federal regulation of greenhouse gas emissions from sources covered by the carbon tax, and eliminate the excise taxes on gasoline and diesel fuels.
