The REPEAT Project has released a 2024 Annual U.S. Emissions Pathway update, incorporating revised assumptions and data updates to reflect announced projects, sales and deployment data, and recently published industry outlooks. This comprehensive update to the 2023 analysis of the impacts of the Inflation Reduction Act (IRA) includes recently finalized federal regulations on power plants, on-road vehicles, oil and gas methane emissions, and appliance and lighting efficiency standards, and includes benchmarking against the previously published REPEAT analysis.
As with previous REPEAT work, this update was developed with EER’s modeling platforms and finds:
Even with projections that reflect higher costs and slower cost declines than previous projections, current policy scenarios reduce GHG emissions by roughly one gigaton by 2030 compared to 2023 emissions supported by federal regulations and the IRA.
The transportation and power sectors account for nearly half of these emission reductions, but current policies deliver emission reductions across all sectors as compared to frozen policy.
A gap remains between what is necessary to follow the net-zero emissions by 2050 pathway and revised macro-economic assumptions, technology adoption projections, and increased resource costs associated with inflation and higher borrowing costs, which have shifted emissions upwards relative to the 2023 analysis.
