The Inflation Reduction Act (IRA) will make significant progress toward achieving the U.S.’s Nationally Determined Contribution (NDC) to the Paris Agreement of reducing emissions 50 to 52 percent below 2005 levels by 2030. But additional, economy-wide reductions are required to close the remaining IRA-NDC gap. This research used the U.S. Energy Policy Simulator to identify policies capable of achieving the U.S. NDC. The modeling finds additional federal and state actions can close the gap, while creating 2.7 million jobs, adding $700 billion to the economy, and avoiding $1.7 trillion in climate damages by 2030.
