Earlier in July, we wrote about what climate programs got cut in the One Big Beautiful Bill (OBBB) that passed on July 4, 2025. Now, drawing on analysis from the Congressional Budget Office (CBO) estimates published June 29, 2025, we can understand how much funding is expected to be clawed back by program. This list includes programs identified in the CBO estimates and may not include all climate programs impacted by the OBBB. Specifically, the law would cut any non-obligated funding for certain programs. Note: this does not cover the significant tax credit changes.
In Table 1, we are tracking a total of $27 billion in funding rescissions for programs tracked on the Climate Program Portal. The largest rescission was for the DOE loan programs including three core programs listed in the CBO estimates: Tribal Energy Loan Guarantee Program, Funding for Department of Energy Loan Programs Office, and Advanced Technology Vehicle Manufacturing Loan Program. For a breakdown by program within the DOE loan programs, see here. It is unclear the impact of these cuts on existing loan guarantees and conditional loan offers. Reporting from Heatmap News highlights the potential impact of these cuts that finance much larger loans:
“Then there’s the Energy Infrastructure Reinvestment Program, which the IRA stood up with a whopping $250 billion in lending authority to transition and transform existing fossil fuel infrastructure for clean energy purposes. Now, OBBBA has axed the program’s remaining $5 billion in credit subsidies and replaced it with $1 billion in new subsidies for projects that “retool, repower, repurpose, or replace” existing energy infrastructure, with a focus on expanding capacity and output as opposed to decarbonizing the economy. It also refashioned the program as the predictably-named “Energy Dominance Financing” initiative.”
There are also considerable cuts to the Neighborhood Access and Equity Grant Program, Low-Carbon Transportation Materials Grants, Environmental and Climate Justice Block Grants, and Clean Heavy-Duty Vehicles. The $2.4 billion cut to the Neighborhood Access and Equity Grant Program is particularly steep as the program was appropriated $3.2 billion, meaning only $800 million was obligated. There is also a significant cut to Conservation programs including the Regional Conservation Partnership Program (RCPP), however the exact amount cut from that program remains unclear (some reporting indicates that the Department of Agriculture saw rescissions of $11 billion in this law for various programs).

“OBBB Section Number” refers to the section number in the CBO estimates. Programs here include any programs tracked on the Climate Program Portal. Funding rescinded may include both Inflation Reduction Act appropriations as well as other appropriations. Note: the CBO estimates do not appear to include all cost savings estimates, for instance for the following programs that were rescinded in the OBBB: Transmission Facility Financing, Grants to Facilitate the Siting of Interstate Electricity Transmission Lines and Interregional and Offshore Wind Electricity Transmission Planning, Modeling, and Analysis.

What does this mean?
It is unclear how much of this funding was announced (or awarded) to recipients but not yet obligated (i.e. formalized). We will track closely to understand the implications for other programs not on this list.
