Amount of emissions compared to GDP falls as country prepares to hit its pledged targets

China is expected to contribute more to help bridge the emission gap to achieve the Paris Agreement, after the United Nations warned the world is not yet on track to hit goals set in the pact that came into force on Friday.

"Although China remains the world's largest carbon emitter, the nation is making quick progress on transforming to low-carbon growth and is on track to fulfill its Paris pledges," said Zou Ji, deputy director of the National Center for Climate Change Strategy, noting that the growth in coal use has been much slower than the growth in the economy in recent years.
