US-China climate deal

BEIJING — A groundbreaking agreement struck Wednesday by the United States and China puts the world's two worst polluters on a faster track to curbing the heat-trapping gases blamed for global warming. With the clock ticking on a worldwide climate treaty, the two countries sought to move beyond their troubled history as environmental adversaries and spur other nations.

The U.S., a chief proponent of the prospective treaty, is setting an ambitious new goal to stop pumping as much carbon dioxide into the air. China, whose appetite for cheap energy has grown along with its burgeoning economy, agreed for the first time to a self-imposed deadline of 2030 for when its emissions will top out.

Yet it wasn't clear how either the U.S. or China would meet their goals, nor whether China's growing emissions until 2030 would negate any reductions in the U.S.

Still, the dual announcements from President Barack Obama and Chinese President Xi Jinping, unveiled Wednesday in Beijing, came as a shock to environmentalists who had pined for such action but suspected China's reluctance and Obama's weakened political standing might interfere.

Republicans were equally taken aback, accusing Obama of saddling future presidents with an unrealistic burden.

This unrealistic plan that the president would dump on his successor would ensure higher utility rates and far fewer jobs," said Sen. Mitch McConnell, R-Ky., who is set to become the majority leader early next year.

Under the agreement, Obama set a goal to cut U.S. emissions between 26 and 28 percent by 2025, compared with 2005 levels. Officials have said the U.S. is already on track to meet Obama's earlier goal to lower emissions 17 percent by 2020, and that the revised goal meant the U.S. would be cutting pollution roughly twice as fast during a five-year period starting in 2020.

China, whose emissions are growing as it builds new coal plants, set a target for its emissions to peak by about 2030 — earlier if possible — with the idea being that its emissions would then start falling. Although that goal still allows China to keep pumping more carbon dioxide for the next 16 years, it marked an unprecedented step for Beijing, which has been reluctant to be boxed in on climate by the global community.

World leaders who have been pressing for a global climate treaty heralded the deal, with U.N. Secretary-General Ban Ki-moon urging all other nations to follow Obama's and Xi's lead by announcing their own emissions targets by early next year. Former Vice President Al Gore, a prominent environmentalist, called the Chinese move "a signal of groundbreaking progress from the world's largest polluter."
