The REPEAT Project provides regular, timely, and independent environmental and economic evaluation of federal energy and climate policies as they’re proposed and enacted. Dive into the details for each of the policies analyzed by the project to date below.
Use our Data Explorer tool to compare energy usage by category for each policy we evaluate, relative to benchmarks or other policies. Jump to Data Explorer

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.Read more
The original version of the Build Back Better Act, introduced in September 2021 (H.R. 5376, H. Rept. 117-130), contained a broader range of policies to deploy clean energy and energy efficiency than the final bill passed the House in November 2021. This scenario helps track how the bill evolved from initial introduction to final passage in the House and the impact of legislative changes made during negotiations over the bill.Read more
This bipartisan infrastructure investment bill (H.R. 3684) passed the House and Senate and was signed into law in November 2021. The law makes major investments in surface transportation, including rail and public transit, and climate resilient infrastructure. It also supports expansion of electricity transmission and CO2 pipeline networks, funds building weatherization and EV charger stations, and invests in demonstration and early deployment of a range of advanced energy technologies.Read more
This scenario captures the range of existing policies as of the start of the 117th Congress and inauguration of President Biden in January 2021 and helps set a benchmark against which progress towards net-zero made during the current Administration and Congressional term can be measured.Read more
This scenario reflects a cost-optimized pathway to reduce economy-wide U.S. greenhouse gas emissions 50% below 2005 levels by 2030 and to net-zero by 2050. It is one of several possible paths to net-zero but serves as an illustrative benchmark to assess whether or not the United States is on track to reach climate mitigation goals.Read more
