Projecting and Accelerating U.S. Greenhouse Gas Reductions

Projecting and Accelerating U.S. Greenhouse Gas Reductions

More than 190 nations representing more than 95 percent of global greenhouse gas emissions offered “nationally determined contributions” (NDCs) to the Paris Agreement reached in December 2015. The NDC submitted by the Obama administration on behalf of the United States is an economy-wide target to reduce net greenhouse gas emissions 26 to 28 percent below 2005 levels by 2025. The Trump administration is now weighing whether to “suspend, revise, or rescind” policies to help meet this goal, and has announced its intent to withdraw from the Paris Agreement. President Trump has also suggested the possibility of “re-entry” under revised terms; one option may be a recalibrated U.S. NDC. Analyses suggest that even with some key climate policies rolled back, U.S. emissions in 2025 could range from 14 percent to 18 percent below 2005 levels. In the absence of additional federal policy, stronger action by states, cities and companies can help reduce emissions further. The brief looks at progress in reducing U.S. emissions, how existing and proposed policies may affect emissions through 2025, and additional steps that can achieve stronger reductions.

Achieving the United States' Intended Nationally Determined Contribution

More than 180 nations representing more than 95 percent of global greenhouse gas emissions offered “intended nationally determined contributions” (INDCs) to the Paris Agreement reached in December 2015. The United States’ INDC is an economy-wide target to reduce net greenhouse gas emissions 26 to 28 percent below 2005 levels by 2025. Available analyses suggest that the United States could reduce emissions by more than 22 percent with policies either already in place or soon anticipated. Options for achieving further reductions to meet the 2025 target may include additional policies, technological advances, and stronger action by cities and companies. Concerted efforts across multiple fronts could reasonably produce the reductions needed to meet the goal. Specifically, this paper looks at the progress that has been achieved since 2005, the effect existing and proposed policies will have by 2025 as well plausible steps to fill the gap.

Nuclear power supplies more than 60 percent of the nation’s zero-carbon electricity. The planned retirement of five nuclear reactors could make it tougher to meet U.S. climate goals.  A C2ES brief examines the pressures on the nation’s nuclear fleet and possible climate implications of future retirements.
