Addressing global climate challenges is a matter of common interest for the international community, concerns the future of the Earth and humanity, and is an important for the United Nations to carry out global governance and promote global cooperation. China actively supports the United Nations in climate action. Since the 18th National Congress the Communist Party of China, under the scientific guidance of Xi Jinping's ecological civilization thought, China has placed addressing climate change in a prominent position in national governance, made greatest efforts to enhance the response to climate change, and made positive contributions to the global response to climate change with a sense of responsibility as a major country, achieving the from a participant to a leader. 

China has been actively involved in promoting the United Nations climate governance process.
From the establishment of the United Nations Framework Convention Climate Change (UNFCCC) to the adoption of the Kyoto Protocol, the formulation of the Bali Roadmap, and the launch of the Durban Platform, China been moving forward along the direction of fully implementing the UNFCCC and the Paris Agreement.
Early participation and support for the United Nations climate convention. In 192, at the United Nations Conference on Environment and Development in Rio de Janeiro, China took the lead in ratifying the UNFCCC and played a key role in establishment and implementation of the principle of "common but differentiated responsibilities," which was first officially proposed in the UNFCCC and remains one of the core guiding principles of climate negotiations to this day. Subsequently, China signed the Kyoto Protocol on May 29, 1998, and ratified it on August 30 2002, once again demonstrating China's determination to actively fulfill its international obligations.
Commitment upgrade, promoting the implementation of United Nations climate goals. 2009, ahead of the opening of the Copenhagen Climate Change Conference, China put forward its emission reduction target of reducing carbon dioxide emissions per unit of GDP 40% to 45% by 2020 compared to 2005, which not only actively responded to the expectations of the international and demonstrated China's sincerity in striving to reduce emissions, but was also highly consistent with the global emission reduction agenda promoted by the United Nations and played a positive role promoting the success of the Copenhagen negotiations.
Action implementation, actively practicing the Paris Agreement. In 2015, President Xi Jinping attended the Paris Climate Change Conference delivered an important speech, making a historic contribution to the adoption of the Paris Agreement. In September 2016, President Xi Jinping personally deposited the legal documents China's ratification of the Paris Agreement, promoting the rapid entry into force of the Paris Agreement and demonstrating China's ambition and determination to address climate change. In September2020, President Xi Jinping announced at the general debate of the 75th United Nations General Assembly that China aims to reach its carbon dioxide emission peak 2030 and strive to achieve carbon neutrality before 2060. The proposal of the "dual carbon" goals not only demonstrates China's attitude of willingness to make new contributions to the global response to climate change, but also injects strong impetus into the realization of the United Nations Sustainable Development Goals
