Reducing Greenhouse Gas Emissions in the United States Using Existing Federal Authorities and State Action

This report presents an analysis of potential GHG emissions reductions under existing U.S. federal authorities and announced state actions through 2030.

Key Findings

Executive Summary

WRI’s analysis of potential greenhouse gas emissions reductions by federal and state governments suggests a range of potential outcomes is possible. On the federal level, whether reductions are achieved at the lower end or upper end of the range shown in Figure 1 depends on the extent to which the Obama Administration and subsequent administrations use existing regulatory authority to go after reductions shown to be technically possible in the literature. On the state level, whether reductions are realized at the lower or upper end of the range projected in Figure 2 depends similarly on the continued resolve by governors and legislative leaders in the 25 states counted as having taken actions. The findings set out here represent an assessment of what is possible given available inputs for some key sectors. It does not include potential emissions reductions achievable through federal policies to reduce vehicle miles traveled, management of agricultural lands and forests, new federal investments in areas such as energy efficiency, renewable energy infrastructure, or other areas that could yield reductions, nor new federal legislation of any kind.
