Working to find actionable solutions to the nation's key challenges.

By Blair Beasley

In 2014, former President Barack Obama’s Environmental Protection Agency (EPA) proposed the Clean Power Plan to regulate carbon dioxide emissions from existing power plants for the first time. The rule utilized Section 111(d) of the Clean Air Act. President Donald Trump campaigned on repealing the regulation. Under the Trump administration, EPA has since moved forward to carry out that promise.

The timeline below chronicles key regulatory and legal events.
