CLOSING THE EMISSIONS GAP BETWEEN THE IRA AND 2030 U.S. NDC: POLICIES TO MEET THE MOMENT

The report argues that while the Inflation Reduction Act (IRA) significantly advances U.S. climate goals, it is insufficient on its own to meet the 2030 NDC. Using the Energy Policy Simulator (EPS), the authors propose a comprehensive set of additional federal, state, and local policies across the electricity, industry, transportation, and building sectors. The electricity sector is identified as the primary driver for 2030 reductions due to its ability to decarbonize faster than sectors limited by slow stock turnover. Proposed measures include a nationwide 80 percent clean electricity standard, stricter tailpipe emissions standards, and the electrification of industrial and building heating. The report estimates that this combined policy pathway would create 2.7 million additional jobs, grow GDP by $700 billion, and avoid 3,900 premature deaths by 2030.

• The Inflation Reduction Act (IRA) is expected to reduce 2030 U.S. emissions to 37 to 43 percent below 2005 levels, which is a significant improvement over the pre-IRA projection of 25 percent, but still falls short of the 50 to 52 percent NDC target.
• The electricity sector is the most critical for rapid decarbonization by 2030 because it is less constrained by the 'stock turnover' dynamic—the slow replacement rate of capital equipment—that limits the pace of emissions reductions in buildings, transportation, and industry.
• To meet the NDC, the electricity sector must reach 80 percent clean electricity by 2030 and eliminate all unabated coal generation, requiring a combination of federal regulations on coal plants and state-level clean electricity standards.
• Industrial emissions reductions for the NDC require the electrification of low-temperature heat via heat pumps, tighter energy efficiency standards, and new regulations to capture fugitive methane and nitrous oxide emissions.
• Achieving the NDC in the transportation sector requires stringent federal and state tailpipe and fuel economy standards to reach a 62 percent zero-emission vehicle (ZEV) sales share for passenger cars and trucks by 2030.
• Building sector decarbonization depends on transitioning to all-electric appliances and adopting strict building codes, with the NDC scenario assuming 62 percent of new equipment that would otherwise be fossil-fueled is electrified by 2030.
• The proposed NDC policy pathway, in addition to the IRA, is estimated to create 2.7 million additional jobs, increase GDP by $700 billion (1.7 percent), and avoid 3,900 premature deaths in 2030.
• The IRA is projected to lower global costs for clean energy technologies by 2030, specifically reducing solar PV costs by 3.8 percent and wind technology costs by 2.6 percent, potentially saving $11 billion annually.
• Combined IRA and NDC policies could avoid a cumulative $1.7 trillion in climate damages between 2023 and 2030, based on the EPA's social cost of carbon.
