The United States is the worldâs second largest emitter of GHGs, but its total net emissions were just 6 billion tons CO2 e in 2014 (EPA 2016). Under the Paris Agreement, all countries have put forward strategies for domestic action. Specifically, each party will prepare and implement successive NDCs that chart a course for emissions reductions over time. To date, the vast majority of countries, including all major economies, have set their contributions for 2025 or 2030, with the U.S. NDC setting a target of 26-28 percent GHG reductions in 2025 from 2005 levels. The largest trading partners of the U.S. have all set near-term targets and have undertaken serious actions to deliver against them (Figure 7.1).
