This book examines China's greenhouse gas emissions and mitigation policies. Debate on potential climate change legislation in the United States has been influenced by China's surging GHG emissions, and uncertainty over whether, how, and when China might alter that trend. There is concern that strong U.S. domestic action taken without Chinese reciprocity would unfairly advantage China in global trade, and fail to slow significantly the growth of atmospheric concentrations of GHGs. The governments of both China and the United States have indicated some closure of their gap on future actions to address climate change by agreeing on national pledges to GHG targets and mitigation actions rather than binding international obligations. China is also engaged with many other countries in bilateral programs to build its governance and technological capacities to abate its GHG emissions.
