Reports

A series of reports summarizing key findings from REPEAT Project analysis of proposed and recently enacted federal energy and climate policies.

Electricity Transmission is Key to Unlock the Full Potential of the Inflation Reduction Act

Previously, REPEAT Project estimated that Inflation Reduction Act could cut U.S. greenhouse gas emissions by roughly one billion tons per year in 2030. But that outcome depends on more than doubling the historical pace of electricity transmission expansion over the last decade in order to interconnect new renewable resources and meet growing demand from electric vehicles, heat pumps, and other electrification. This report assesses the role of electricity transmission in enabling the full emissions reduction potential of the Inflation Reduction Act (IRA).
Download this REPEAT Project Report on the importance of electricity transmission expansion to unlock the full emissions reduction potential of the Inflation Reduction Act. (This version, September 22, 2022.)

Preliminary Report: The Climate and Energy Impacts of the Inflation Reduction Act of 2022

Download the REPEAT Project's Preliminary Report for analysis of the energy system and climate impacts of the recently introduced Inflation Reduction Act of 2022. Learn how the bill cuts U.S. emissions by roughly 1 billion tons by 2030 and compare to previously introduced and enacted legislation. (This version, August 4, 2022.)

Summary Report: The Climate Impact of Congressional Infrastructure and Budget Bills

The Infrastructure Investment and Jobs Act (H.R. 3684) signed into law on November 15th contains billions of dollars for energy efficiency, electric vehicle charging, transmission networks, and historic investments in clean energy innovation. But how far will it cut U.S. emissions of greenhouse gases? What are the impacts of the Build Back Better Act (H.R. 5376) still pending in Congress? Will current policies put the United States on track to cut emissions 50% below peak levels by 2030 and net-zero by 2050?

Download the REPEAT Project Summary Report for details on the impact of recently enacted and pending policies on carbon dioxide emissions, clean energy and electric vehicle deployment, household energy costs, energy related jobs, air pollution and more. (This version, February 28, 2022.)

Preliminary Report: The Climate Impact of Congressional Infrastructure and Budget Bills

With Congress considering infrastructure and budget bills that would provide unprecedented public investments in clean energy infrastructure, clean vehicles, and other low-carbon solutions, the REPEAT Project is releasing this preliminary report on the national-scale impacts of the Build Back Better Act being considered in the House of Representatives (H.R. 5376, as reported by the Budget Committee on September 27, 2021) and the Infrastructure Investment and Jobs Act (H.R. 3684, as passed by the Senate on August 10, 2021).

Download the report for details on the impact of these pending policies on carbon dioxide emissions, clean energy and electric vehicle deployment, fossil energy use, and more. (This version, October 20, 2021.)

Addendum to Preliminary Report (11/12/21)

Since release of our "Preliminary Report: The Climate Impact of Congressional Infrastructure and Budget Bills," on October 20th, 2021, the U.S. House of Representatives passed the Infrastructure Investment and Jobs Act ( H.R. 3684 ) on November 6th and introduced a new version of the Build Back Better Act ( H.R. 5376, RCP 117-18 ) on November 3, 2021.


There are a significant number of changes to the Build Back Better Act, which the REPEAT Project has carefully documented along with a thorough catalog of all climate and clean energy provisions in the final Infrastructure Bill in this document.

This addendum to our preliminary report compiles emissions results from our original analysis of the Build Back Better Act (‘BBB 1.0’) as reported by the Budget Committee on September 27, 2021 but without the Clean Electricity Performance Program (the most substantive single change from BBB 1.0 to BBB 2.0) as well as our initial analysis of the Infrastructure Bill impacts.

Passed by the U.S. House of Representatives on November 19, 2021, the Build Back Better Act (H.R. 5376) contains over $500 billion in tax credits, grants, rebates, and other policies to deploy clean electricity, electric vehicles, building electrification and efficiency, hydrogen, carbon capture and storage, and low-carbon transportation fuels. The bill also funds agricultural practices that could sequester carbon in soils, provides funding to fight wildfires and protect forests, and imposes a fee on upstream emissions of methane in oil and gas sectors. It remains stalled in the U.S. Senate at this time.
