WASHINGTON—Aiming to jolt the rest of the world to action, President Barack Obama moved ahead Sunday with even tougher greenhouse gas cuts on American power plants, setting up a certain confrontation in the courts with energy producers and Republican-led states.
In finalizing the unprecedented pollution controls, Obama was installing the core of his ambitious and controversial plan to drastically reduce overall U.S. emissions, as he works to secure a legacy on fighting global warming. Yet it will be up to Obama’s successor to implement his plan, which reverberated across the 2016 presidential campaign trail.
Opponents planned to sue immediately, and to ask the courts to block the rule temporarily. Many states have threatened not to comply.
The Obama administration estimated the emissions limits will cost $8.4 billion annually by 2030. The actual price won’t be clear until states decide how they'll reach their targets. But energy industry advocates said the revision makes Obama’s mandate even more burdensome, costly and difficult to achieve.
“They are wrong,” Environmental Protection Agency Administrator Gina McCarthy said flatly, accusing opponents of promulgating a “doomsday” scenario.
Last year, the Obama administration proposed the first greenhouse gas limits on existing power plants in U.S. history, triggering a yearlong review and more than 4 million public comments. On Monday, Obama was to unveil the final rule publicly at an event at the White House.
“Climate change is not a problem for another generation,” Obama said in a video posted to Facebook. “Not anymore.”
