On the eve of the Copenhagen Climate Change Conference, China made a solemn commitment to the world: to reduce carbon intensity per unit of GDP by 40-45% by 2020, compared to 2005 levels; to increase the non-fossil share of energy consumption to around percent by 2020. In the past ten years, China has firmly implemented the national strategy to actively address climate change, and unswervingly pushed forward the work to address climate change. By the end of 2020, China's carbon intensity had decreased by about 48.4% compared with 2005, and non-fossil energy accounted for 15.9% of primary energy consumption, significantly exceeding the 2020 targets. Not only has China exceeded its climate commitments to the international community ahead of schedule, in September 2020 China announced to would scale up its NDCs, strive to peak CO emissions before 2030, and achieve carbon neutrality before 2060. In October 2021, China officially submitted "China's Achievements, New Goals and New Measures for Nationally Determined Contributions" to the secretary of UNFCCC and including "strive to peak carbon dioxide emissions by 2030, and strive to achieve carbon dioxide emissions by 2060. China's updated NDC goals are as follows: aims to have CO emissions peak before 2030 and achieve carbon neutrality before 2060. By 2030, CO2 emissions per unit of GDP will have dropped by more than 65% compared
