“This Tuesday, I’ll lay out my vision for where I believe we need to go — a national plan to reduce carbon pollution, prepare our country for the impacts of climate change, and lead global efforts to fight it,” the president said. “This is a serious challenge — but it’s one uniquely suited to America’s strengths.”

In Saturday’s statement, Obama emphasized the economic opportunities that could come from tackling carbon emissions.

“We’ll need scientists to design new fuels, and farmers to grow them,” he said. “We’ll need engineers to devise new sources of energy, and businesses to make and sell them.”
