It’s finally here, the biggest climate action of Obama’s presidency: On Monday morning, the EPA will issue a final Clean Power Plan rule that will, for the first time, govern carbon emissions from power plants. And it’s stronger in several ways than the draft plan that was released in June 2014.

The White House began bragging about its accomplishment on Sunday. First it released a feel-good video. Then there was a press call with EPA Administrator Gina McCarthy. On Monday, President Obama himself will speak about the plan.

Even before any of that, the accolades from environmental and public health groups started rolling in. Carol Browner, former EPA administrator and now chair of the League of Conservation Voters, was typical in calling it “a visionary policy that sets our nation on the path to cleaner, renewable energy for the future.”
