China has pledged to cut its greenhouse gas emissions per unit of gross domestic product by 60-65% from 2005 levels.
The plan was unveiled Tuesday following a meeting between visiting Chinese Premier Li Keqiang and French President Francois Hollande in Paris.
Li said Beijing's intended nationally determined contributions (INDCs) are based on China's national conditions, stage of development, strategies on sustainable development, and international responsibilities.
The plan has been submitted to the UN Climate Change Secretariat ahead of a crucial climate change meeting in Paris in December, Li said.
China's carbon dioxide emissions will peak by 2030, according to the document. The economic giant aims to reduce its carbon dioxide emissions per unit of GDP by 60-65% by 2030, from 2005 levels. Earlier, Beijing set to cut the carbon intensity target by 40-45% by 2020.
The country also aims to increase the share of non-fossil fuels in its primary energy consumption to about 20% by 2030. Beijing previously set a goal of receiving around 15% of its energy from clean source by 2020.
In a separate announcement, the US and Brazil pledged to increase production of electricity from renewable sources to represent 20% of their electricity production by 2030. That is three times as much renewable energy as the US currently produces and twice as much as is produced in Brazil.
