Climate change looms large among the many issues on the table at the upcoming meeting of Presidents Xi and Obama in the U.S. next week. Any new developments at that meeting will build on announced domestic efforts to address the issue, starting with a joint declaration in Beijing last November of what would become the main elements of each country’s Intended Nationally Determined Contribution (or INDC). In its INDC, China has pledged to reverse the increase in its CO2 emissions to peak by 2030 or sooner.
