In light of the overwhelming scientific consensus on climate change and its worsening impacts, and the related issue of air pollution from burning fossil fuels, China and the United States recognize the urgent need for action to meet these twin challenges.

Both sides reaffirm their commitment to contribute significantly to successful 2015 global efforts to meet this challenge. Accordingly, China and the United States will work together, within the vehicle of the China-U.S.

Climate Change Working Group (CCWG) launched last year, to collaborate through enhanced policy dialogue, including the sharing of information regarding their respective post-2020 plans to limit greenhouse gas emissions.

Regarding practical cooperative actions to reduce greenhouse gas emissions and other air pollutants, the two sides have reached agreement on the implementation plans on the five initiatives launched under the CCWG, including Emission Reductions from Heavy Duty and Other Vehicles, Smart Grids, Carbon Capture Utilization and Storage, Collecting and Managing Greenhouse Gas Emissions Data, and Energy Efficiency in Buildings and Industry, and commit to devote significant effort and resources to secure concrete results by the Sixth China-U.S. Strategic and Economic Dialogue in 2014.
