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.

Oo February 15, the bipartisan House Climate Solutions Caucus introduced their first piece of legislation, the Challenges & Prizes for Climate Act (H.R.5031). Sponsored by Representative Dan Lipinski (D-IL-3) with five other caucus members signed on as original cosponsors, the bill aims to establish a Climate Solutions Challenges program within the Department of Energy to fund clean energy prize competitions and consequently spur innovation in key areas critical to combating climate change. 

Following several executive orders issued by President Donald Trump, the Department of the Interior and the EPA announced rulemaking revisions to offshore drilling protections, fracking regulations, and the Clean Power Plan in the final days of 2017.
