Carbon Pollution Standards

Clean Power Plan Proposed Rule

On June 2, 2014, EPA proposed a commonsense plan to cut carbon pollution from power plants. States, cities and businesses across the country are already taking action to address the risks of climate change. EPA's proposal builds on those actions and is flexible - reflecting that different states have a different mix of sources and opportunities, and reflecting the important role of states as full partners with the federal government in cutting pollution. This proposal will maintain an affordable, reliable energy system, while cutting pollution and protecting our health and environment now and for future generations.
