Leaders of 11 Chinese cities and provinces on Tuesday will announce plans to cut carbon emissions earlier than China's national target of 2030, a move meant to build momentum for a global accord in December, according to the White House.
Those announcements, as well emission-reduction commitments from more than a dozen U.S. states and cities, will form part of a joint declaration that municipal and regional leaders from the world's two biggest greenhouse gas-emitting countries will sign at a U.S.-China meeting in Los Angeles on Tuesday and Wednesday.
The summit builds on a key climate change deal reached in November between U.S. President Barack Obama and Chinese President Xi Jinping. The United States agreed to lower greenhouse emissions as much as 28 percent below 2005 levels by 2025, and China pledged that its emissions would peak by 2030, according to the White House.
Tuesday's announcement is "a very important component of our broader efforts to deepen climate cooperation and to show that ... the two largest emitters in the world are taking seriously our obligation to meet the ambitious goals that we set out last year," said Brian Deese, a senior adviser to Obama. Xi is visiting the United States next week.
