In this regard, China Special Envoy for Climate Change Xie Zhenhua and U.S. Special Presidential Envoy for Climate John Kerry met in Beijing from 16 to 19 July 2023 and at Sunnylands, California, from 4 to 7 November 2023 and released the followings:
1. China and the United States recall, reaffirm, and commit to further the effective and sustained implementation of the April 2021 China-U.S. Joint Statement Addressing the Climate Crisis and the November 2021 China-U.S. Joint Glasgow Declaration on Enhancing Climate Action in the 2020s.
2. China and the United States recognize that the climate crisis has increasingly affected countries around the world. Alarmed by the best available scientific findings including the IPCC Sixth Assessment Report, China and the United States remain committed to the effective implementation of the UNFCCC and the Paris Agreement, reflecting equity and the principle of common but differentiated responsibilities and respective capabilities, in light of different national circumstances, to achieve the Paris Agreement’s aim in accordance with its Article 2 to hold the global average temperature increase to well below 2 degrees C and to pursue efforts to limit it to 1.5 degrees C, including efforts to keep 1.5 degrees C within reach.
3. China and the United States remain committed to the effective implementation of the Paris Agreement and decisions thereunder, including the Glasgow Climate Pact and the Sharm el-Sheikh Implementation Plan. Both countries stress the importance of COP 28 in responding meaningfully to the climate crisis during this critical decade and beyond. They are aware of the important role they play in terms of both national responses and working together cooperatively to address the goals of the Paris Agreement and promote multilateralism. They will work together and with other Parties to the Convention and the Paris Agreement to rise up to one of the greatest challenges of our time for present and future generations of humankind.
4. China and the United States decide to operationalize the Working Group on Enhancing Climate Action in the 2020s, to engage in dialogue and cooperation to accelerate concrete climate actions in the 2020s. The Working Group will focus on the areas of cooperation that have been identified in the Joint Statement and the Joint Declaration, including on energy transition, methane, circular economy and resource efficiency, low-carbon and sustainable provinces/states & cities, and deforestation, as well as any agreed topics. The Working Group will carry out information exchanges on policies, measures, and technologies for controlling and reducing emissions, share their respective experiences, identify and implement cooperative projects, and evaluate the implementation of the Joint Statement, the Joint Declaration, and this Statement. The Working Group is co-led by the two special envoys on climate change, with the appropriate participation of officials from the relevant ministries and government agencies of the two countries.
5. China and the United States will, on the road to COP 28 and beyond, accelerate, inter alia, the following concrete actions, including practical and tangible collaborative programs and projects under the Working Group.
Energy Transition
6. Both countries support the G20 Leaders Declaration to pursue efforts to triple renewable energy capacity globally by 2030 and intend to sufficiently accelerate renewable energy deployment in their respective economies through 2030 from 2020 levels so as to accelerate the substitution for coal, oil and gas generation, and thereby anticipate post-peaking meaningful absolute power sector emission reduction, in this critical decade of the 2020s.
7. Both sides agree to restart the China-U.S. Energy Efficiency Forum to deepen policy exchanges on energy-saving and carbon-reducing solutions in key areas including industry, buildings, transportation, and equipment.

14. Recognizing the importance of developing circular economy and resource efficiency in addressing the climate crisis, relevant government agencies of the two countries intend to conduct a policy dialogue on these topics as soon as possible and support enterprises, universities, and research institutions of both sides to engage in discussions and collaborative projects.
15. China and the United States are determined to end plastic pollution and will work together and with others to develop an international legally binding instrument on plastic pollution, including the marine environment.
Subnational Cooperation
16. China and the United States will support climate cooperation among states, provinces, and cities with regard to areas including, inter alia, the power, transportation, buildings, and waste sectors. Both sides will facilitate subnational governments, enterprises, think tanks, and other stakeholders to actively participate in the cooperation. The two countries will meet periodically, as agreed, for policy dialogue, best practices sharing, information exchange, and to facilitate cooperative programs.
17. China and the United States intend to hold a high-level event on subnational climate action in the first half of 2024.
18. Both sides welcome with appreciation existing subnational cooperation between the two countries and encourage states, provinces, and cities to promote practical climate cooperation.
Forests
19. Both sides commit to advance efforts to halt and reverse forest loss by 2030, including by fully implementing through regulation and policy, and effectively enforcing, their respective laws on banning illegal imports. They intend to engage in discussions and exchanges, including under the Working Group, on ways to improve efforts to strengthen implementation of this commitment.
GHG and Air Pollutant Reduction Synergy
20. Both countries intend to cooperate in promoting relevant policies and measures and the deployment of technologies to enhance synergy of controlling GHG emissions and air pollutants, including NOX, VOCs, and other tropospheric ozone precursors.
2035 NDCs
21. Reaffirming the nationally determined nature of NDCs, and recalling Article 4.4 of the Paris Agreement, both countries’ 2035 NDCs will be economy-wide, include all greenhouse gases, and reflect the reductions aligned with the Paris temperature goal of holding the increase in global average temperature to well below 2 degrees C and pursuing efforts to limit the temperature increase to 1.5 degrees C.
COP 28
22. China and the United States, with the United Arab Emirates, invite countries to a Methane and Non-CO2 Greenhouse Gases Summit at COP 28.
23. China and the United States look forward to the first Global Stocktake under the Paris Agreement, which is a vital opportunity for the Parties to reflect on ambition, implementation, and cooperation, in line with the Paris temperature goal to hold the global average temperature increase to well below 2 degrees C and pursue efforts to limit it to 1.5 degrees C, and the Parties’ resolve to keep a 1.5 degree C limit on temperature rise within reach.
24. Both countries are committed to working with each other and with other Parties to adopt a consensus Global Stocktake decision. In the view of both countries, the decision:
should reflect that there has been substantial positive progress toward achieving the objectives of the Paris Agreement, including that the Agreement has catalyzed action by both Parties and non-Party stakeholders and that the world is considerably better off in terms of its temperature trajectory than it would have been in the absence of the Agreement;
should take account of equity and be informed by the best available science, including the most recent IPCC reports;
should be balanced across thematic areas, include both retrospective and responsive elements, and be consistent with the design of the Paris Agreement;
should reflect that substantially more ambition and implementation on action and support will be needed to achieve the Paris Agreement’s goals, recognizing different national circumstances;
should send signals with respect to the energy transition (renewable energy, coal/oil/gas), carbon sinks including forests, non-CO2 gases including methane, and low-carbon technologies, etc.;
recognizing the nationally determined nature of NDCs and recalling Article 4.4 of the Paris Agreement, should encourage economy-wide 2035 NDCs covering all greenhouse gases;
should reflect the critical importance of adaptation and be accompanied by a robust decision that delivers an ambitious framework for the global goal on adaptation — one that accelerates adaptation, including developing targets/indicators to enhance adaptation effectiveness; delivering early warning systems for developing country Parties; and strengthening adaptation efforts in key areas (e.g. food, water, infrastructure, health, and ecosystems);
should note the expectation of the developed countries that the $100b goal will be met in 2023, reaffirm the urging of developed country Parties to at least double their provision of adaptation finance; anticipate the adoption by COP 29 of the new collective quantified goal; and make finance flows consistent with the Paris Agreement goals;
should welcome with appreciation the recommendations of the Transitional Committee with respect to establishing funding arrangements to address loss and damage, including the establishment of a fund; and
should emphasize the important role of international cooperation, including that the global nature of the climate crisis calls for the widest possible cooperation and that such cooperation is a critical enabler for achieving ambitious mitigation action and climate-resilient development.
25.China and the United States are committed to further their dialogues, efforts, and collaboration to support the UAE Presidency for the success of COP 28.
