Delivering on the U.S. Climate Commitment: A 10-Point Plan Toward a Low-Carbon Future

This analysis finds that the United States can meet, and even surpass, its announced target to reduce greenhouse gas emissions by 26-28 percent below 2005 levels in 2025 with a comprehensive approach using existing federal laws and state action. After 2025, even deeper reductions will be necessary to avoid the worst impacts of climate change. The paper models two pathways that could reduce emissions 40–42 percent below 2005 levels by 2030, and 50-53 percent by 2040 with new legislation that establishes a price on carbon together with complementary policies across the economy.
