U.S. CO₂ emissions reduction projections under IRA scenarios 2030-2035, by sector
The Inflation Reduction Act (IRA) is projected to spur significant economy-wide carbon dioxide (CO₂) emissions reductions in the United States over the coming decade. In the IRA scenario, economy-wide CO₂ emissions are projected to fall by 35 to 43 percent below 2005 levels by 2030. By comparison, reductions in the No IRA scenario range from 26 to 33 percent. Projections show greater emissions reductions for the IRA scenario compared to the No IRA scenario across all end-use sectors.
The IRA, which was signed into law on August 16, 2022, by President Biden, is the largest climate investment in U.S. history.
