The game-changing U.S.-China climate agreement [video]

The United States and China have already made historic commitments to combat global climate change by reducing their own greenhouse gas emissions.

The United States will cut its emissions by up to 28 percent by 2025, bringing them below 2005 levels. China’s emissions will peak by 2030 and then begin to decline. By 2030, China’s clean-energy sources, such as solar and wind, will account for 20 percent of its energy production.

“We still have a lot of work … but with the United States and China taking the lead, we’re more likely to get there,” says U.S. Treasury Secretary Jack Lew as leaders from both countries meet in Washington June 23–24.
