China the world’s largest emitter of greenhouse gases has announced details of its climate action plan.
The office of Premier Li Keqiang said that emissions “will peak by around 2030” and China would work hard to achieve the target even earlier.
The statement echoes China’s declaration last November following a US-China summit.
China’s pledge comes ahead of talks late this year in Paris to seek a new global deal on climate change.
The statement, released following a meeting in Paris between Li and French President Francois Hollande, said China aimed to reduce its carbon dioxide emissions per unit of GDP by 60-65% by 2030, from 2005 levels.
The carbon intensity target builds on a previous plan to cut carbon intensity by 40-45% by 2020.
China also aimed to increase the share of non-fossil fuels in its primary energy consumption to about 20% by 2030.
Beijing previously set a goal of getting around 15% of its energy from clean sources by 2020.
