China has committed to stabilize its greenhouse gas emissions and increase the percent of non-fossil fuel energy to 20% by 2030. This goal will require significant programmatic and policy changes across all sectors of its economy. The challenge is how to make these changes without incurring measurable political and economic costs. Ideally governments will draw lessons from efforts in other countries, but the Chinese system is unique. Hence it has created its own learning experiences by investing in multiple pilot policies and programs at the provincial and city levels.

China and the United States together emit more than 40 percent of the world’s carbon dioxide (CO₂) according to the latest available data. Therefore any successful global effort to reduce greenhouse gas emissions must include meaningful contributions from both countries. Each country has started down this path by committing to reduce CO₂ emissions and both have announced plans, policies, and programs to meet those commitments. However, the character of the carbon problem in each country is different and so while the plans, programs, and policies they are pursuing have some similarities, the emphasis is different.
