Leaders from 14 Chinese provinces and cities also participated in the meeting and signed a series of cooperation agreements with their U.S. counterparts on emissions reduction targets.

China, the world’s second biggest economy, promised to cut carbon dioxide emissions per unit of GDP by 60 to 65 percent by 2030, from 2005 levels.

To meet that goal, an estimated 6.7 trillion U.S. dollars will be needed to improve energy efficiency and develop renewable sources. Over 50 provinces, cities and municipalities have been chosen as pioneers to carry out the transformation.

“The experience and lessons accumulated by these pioneer cities in the eastern, central and western parts of China can be references for other cities,” said Xie Zhenhua, China’s special representative on climate change.
