“Climate change is happening fast,” Redford says in the advertisement. “We’ve got to stop making the problem worse, and that means reducing carbon pollution from its biggest source, coal-fired power plants. The good news is that President Obama has pledged to act. I just hope the President has the courage of his convictions.”
The advertisements come a day after the International Energy Agency said global energy sector emissions rose 1.4 percent last year to hit an all-time high.
The Obama administration has argued that the Clean Air Act gives it the ability to tighten emissions rules.
But the White House missed its December deadline to enact emissions standards for new coal-fired power plants. It said it needed more time to evaluate comments.
Green groups have threatened to sue the Environmental Protection Agency for its tardiness. They also want Obama to act on emissions from existing power plants, arguing he has the authority to do so through the Clean Air Act.
