Section 60021: Rescission of funding for low-carbon materials for Federal buildings
Executive Summary
Section 60021 rescinds the unobligated balances of Inflation Reduction Act funding that had been made available to the General Services Administration for low-carbon materials in federal buildings.[1] The underlying Inflation Reduction Act provision, section 60503, provided $2.15 billion to the Federal Buildings Fund to acquire and install low-embodied-carbon materials and products in construction or alteration projects at GSA-controlled buildings.[2]
The practical effect is to terminate remaining unused federal support for GSA’s low-carbon construction materials program. Estimates compiled after enactment identify approximately $421 million in unobligated funding rescinded for this program.[3] That does not claw back money already obligated to specific projects, but it prevents GSA from using the remaining balance for additional low-carbon asphalt, concrete, glass, steel, cement, or similar materials in federal building projects.
The environmental and climate impact is negative. Section 60021 removes funding from a program designed to reduce embodied greenhouse-gas emissions in federal construction and to help create stable demand for cleaner construction materials. The harm is partly immediate, because the remaining budget authority is withdrawn, and partly downstream, because fewer federal projects will be able to pay the incremental cost or procurement support needed to use lower-carbon materials.
What Section 60021 Actually Does
Section 60021 is a rescission provision. It does not create a new program, new eligibility rules, or a replacement funding stream. It withdraws the unobligated balances of amounts made available to carry out section 60503 of Public Law 117-169, the Inflation Reduction Act.[1]
Section 60503 had appropriated $2.15 billion to the Federal Buildings Fund for GSA to acquire and install materials and products with substantially lower embodied greenhouse-gas emissions in construction or alteration of buildings under GSA jurisdiction, custody, and control.[2] GSA used this authority as part of its low-embodied-carbon materials program, including federal projects using lower-carbon asphalt, concrete, glass, and steel.[4]
| Program or activity | Amount | What the money supports |
|---|---|---|
| IRA section 60503 low-carbon materials for federal buildings | $2.15 billion originally appropriated | Acquisition and installation of low-embodied-carbon materials and products in GSA construction or alteration projects.[2] |
| OBBBA section 60021 rescission | Approximately $421 million in unobligated balances | Withdrawal of remaining unused budget authority for GSA low-carbon federal building materials.[3] |
GAO reported that, as of January 31, 2025, GSA had $2.15 billion available for low-embodied-carbon materials, had obligated $767 million, and had expended $102 million.[5] The difference between available, obligated, and expended amounts matters because Section 60021 targets unobligated balances. Obligated funds are generally tied to existing commitments, while unobligated funds are the remaining budget authority not yet legally committed.
The rescission therefore affects future or not-yet-obligated work more than already committed work. It narrows GSA’s ability to expand low-carbon material procurement across additional federal building projects and reduces the market signal that federal procurement would otherwise send to domestic producers of cleaner cement, concrete, asphalt, glass, and steel.
Legislative Mechanism
Section 60021 operates through budget rescission. Congress previously appropriated money in the Inflation Reduction Act for a specific GSA purpose: low-carbon materials in federal buildings. Section 60021 then cancels the unobligated portion of that budget authority.
The mechanism is direct and fiscal:
- Identify the Inflation Reduction Act funding source: section 60503 of Public Law 117-169.
- Identify the remaining unobligated balances.
- Rescind those balances.
- Leave already obligated amounts outside the rescission unless another legal authority separately affects them.
This means the section does not repeal GSA’s general building management authority, does not rewrite the Federal Buildings Fund statute, and does not prohibit all future use of low-carbon materials. Instead, it removes dedicated Inflation Reduction Act funding that made those materials easier to procure at scale.
The distinction is important. GSA may still be able to specify lower-carbon materials where procurement law, project budgets, technical requirements, and appropriations allow. But Section 60021 eliminates a dedicated funding stream that was designed to overcome cost, data, supply-chain, and procurement barriers for lower-embodied-carbon construction materials.
Expenditure Tracking and Reporting Protocol
The rescission is likely tracked through several federal budget execution and oversight channels. The core account is the Federal Buildings Fund administered by GSA’s Public Buildings Service. The rescinded amount would be reflected through GSA budget execution records, OMB apportionment and reapportionment controls, Treasury account reporting, and later agency financial reporting. Public visibility may be partial because Section 60021 rescinds unobligated balances rather than creating a new award program with a single public award list.
For projects already obligated before the rescission, spending may continue to appear through contract and award systems, including USAspending.gov and federal procurement reporting, depending on award structure and reporting rules. For rescinded balances, the public may see the budgetary effect in aggregate through CBO, agency budget materials, Treasury reporting, or oversight documents, but it may be harder to isolate project-by-project because the rescinded money represents projects that will not proceed under this funding authority.

The strongest public tracking sources are likely to be CBO estimates, GSA budget documents, GAO or Inspector General reviews, USAspending.gov for already obligated awards, and agency financial statements. GAO has already reported program-level IRA obligations and expenditures for GSA’s low-embodied-carbon materials funding, making it a useful oversight baseline.[5]
The main limitation is that rescinded unobligated balances do not always map neatly to canceled named projects. Some balances may correspond to planned work, contingency amounts, project phases, procurement reserves, or not-yet-awarded contracts. Public datasets may show what was obligated and spent, but not every project, material purchase, or emissions-reduction opportunity that did not occur because the remaining authority was rescinded.
Day-to-Day Government Process Changes
For GSA, Section 60021 changes daily capital planning and procurement decisions. Project teams lose access to remaining dedicated IRA funding for low-carbon materials. That can affect scope decisions, material specifications, bid evaluations, project sequencing, and whether low-carbon alternatives remain financially feasible within ordinary project budgets.
Before the rescission, GSA had a dedicated funding source to support cleaner materials and to apply low-embodied-carbon procurement requirements. GSA’s IRA materials requirements covered major construction inputs, including concrete, cement, concrete masonry units, asphalt, steel, and glass, and required documentation such as product-specific environmental product declarations for many covered products.[6] After the rescission, GSA may still consider those standards, but fewer projects will have dedicated funding to absorb higher costs, documentation burdens, or procurement complexity.
For contracting officers and project managers, the change may mean:
| Government function | Likely change |
|---|---|
| Capital project planning | Fewer projects can rely on dedicated low-carbon materials funding. |
| Procurement | Low-carbon material specifications may become harder to include where they raise costs or reduce bidder pools. |
| Market engagement | GSA has less funding leverage to encourage suppliers to produce compliant low-carbon materials. |
| Emissions accounting | Fewer projects may generate comparable embodied-carbon data through IRA-funded material documentation. |
| Oversight | Review shifts from program expansion and delivery to identifying rescinded balances, remaining obligations, and impacts on selected projects. |
The effect is not only administrative. Federal procurement is large enough to influence supplier behavior. By reducing federal demand for lower-carbon materials, Section 60021 may weaken incentives for manufacturers to invest in environmental product declarations, lower-emissions production processes, and cleaner product lines.
Effects on Consumers
The section does not directly change household taxes, utility bills, rents, or consumer prices. Most consumers will not experience an immediate, visible change from Section 60021.
The consumer effects are indirect. Federal buildings are public assets used by federal workers, contractors, agency visitors, benefit applicants, veterans, taxpayers, and local communities. If low-carbon materials funding is withdrawn, some federal building projects may proceed with conventional materials or be scaled differently. That can reduce the public benefits associated with cleaner construction, including lower lifecycle emissions, improved market availability of lower-carbon materials, and potential long-term innovation in construction supply chains.
There may also be a missed consumer benefit in private markets. Federal procurement can help standardize product documentation and increase production scale. If fewer manufacturers see federal demand for lower-carbon concrete, steel, asphalt, glass, or cement, those products may diffuse more slowly into commercial and residential construction markets. That could make it harder for consumers, tenants, and communities to benefit from lower-carbon building practices over time.
Effects on Businesses
Section 60021 affects businesses unevenly.
Businesses producing or supplying low-embodied-carbon construction materials are the most directly affected. The rescission reduces the remaining federal demand signal for lower-carbon materials in GSA projects. Companies that invested in environmental product declarations, cleaner production methods, alternative mixes, recycled inputs, lower-carbon fuels, or emissions controls may face fewer federally funded opportunities.
Construction contractors and subcontractors may see fewer GSA solicitations with dedicated low-carbon materials funding. Some firms may welcome reduced procurement complexity if low-carbon documentation or material requirements were difficult to satisfy. But firms that had adapted to GSA’s low-carbon requirements may lose a competitive advantage.
| Business category | Likely effect |
|---|---|
| Low-carbon material manufacturers | Negative; reduced federal demand and weaker incentive for cleaner production investments. |
| Conventional material suppliers | Potential short-term benefit if fewer projects require lower-carbon alternatives. |
| Contractors experienced with low-carbon procurement | Negative; fewer federally funded opportunities using specialized compliance experience. |
| Small and regional suppliers | Mixed; reduced documentation pressure for some, but fewer chances to enter cleaner-material supply chains. |
| Environmental product declaration providers and consultants | Negative; lower demand for product documentation tied to GSA-funded procurement. |
The broader market effect is directionally negative for industrial decarbonization. The original program was designed not only to buy cleaner materials for federal buildings, but also to help build demand, data, and supplier capacity in sectors that are emissions-intensive and difficult to decarbonize.
Environmental and Climate Impact
The environmental and climate impact is negative.
Immediately, Section 60021 rescinds remaining unobligated funding for a program whose purpose was to reduce embodied greenhouse-gas emissions in federal construction. The section does not itself approve a polluting project, but it changes the baseline by removing dedicated funding for cleaner construction materials in federal buildings.
The reasonably foreseeable implementation effect is that fewer GSA projects will use IRA-supported low-carbon materials. GSA had announced a major investment in cleaner construction projects across 39 states, the District of Columbia, and Puerto Rico, supporting low-carbon asphalt, concrete, glass, and steel.[4] Rescinding the remaining unobligated balance limits the program’s ability to expand, complete additional phases, or support additional projects.
The downstream climate impact comes from embodied carbon. Cement, concrete, steel, asphalt, and glass are major construction inputs with significant production-related emissions. The IRA program was designed to use federal purchasing power to lower those emissions by requiring or encouraging materials with substantially lower global warming potential and supporting documentation such as environmental product declarations.[6] Removing remaining funding weakens that pathway.
The environmental justice and local community effects are also relevant. Industrial facilities that produce cement, steel, asphalt, and glass can contribute to local air pollution as well as greenhouse-gas emissions. A federal procurement program that rewards cleaner production can help shift demand toward lower-emission practices. Rescinding funds does not require dirtier production, but it reduces federal support for market transformation that could benefit communities near industrial plants, construction corridors, and major public building projects.
Existing environmental and procurement safeguards are not formally repealed by Section 60021. GSA can still use other legal authorities and project funds where available. But the section weakens the practical safeguard created by dedicated funding: the ability to pay for, specify, document, and scale low-carbon materials in federal construction. The result is a cumulative and downstream loss of climate mitigation potential, cleaner-material market demand, and public-sector leadership in industrial decarbonization.
Impact Summary
Section 60021 rescinds approximately $421 million in remaining unobligated funding from a $2.15 billion Inflation Reduction Act program for low-carbon materials in federal buildings.[2][3] Its immediate legal effect is budgetary: GSA loses remaining unused authority for this dedicated program. Its practical effect is broader: fewer federal building projects are likely to receive targeted support for lower-embodied-carbon asphalt, concrete, glass, steel, cement, and related materials.
Consumers are affected indirectly through reduced public investment in cleaner federal buildings and slower diffusion of low-carbon construction practices. Businesses are affected more directly, especially manufacturers, contractors, and consultants that invested in low-carbon materials, environmental product declarations, and GSA-compliant procurement systems.
The environmental and climate effects are negative and risk-increasing because the section rescinds funding that would otherwise support lower-emission construction materials. The harm is immediate as a loss of budget authority, reasonably foreseeable as fewer low-carbon procurement opportunities, and downstream as weaker demand for cleaner industrial production. The affected categories include greenhouse-gas emissions, industrial air pollution, public-sector climate leadership, environmental product transparency, and cumulative decarbonization of construction supply chains.
