Cameco and Brookfield have joined a major partnership with the U.S. government to build a large fleet of new nuclear reactors. The plan centers on Westinghouse reactor technology. It aims to boost the U.S. power supply and speed up the use of low-carbon electricity for industry and data centers. The agreement is worth at least $80 billion in aggregate project value.
A Historic $80B Bet on Nuclear Power
The partnership commits to mobilizing at least $80 billion to build new Westinghouse reactors across the United States. The U.S. government agreed to help arrange financing and to speed permitting and approvals.
The companies say the program will fund both large reactors (AP1000 class) and smaller designs, such as the AP300 small modular reactor (SMR). The aim is repeatable construction and faster delivery.
Officials said the plan includes near-term purchases of long-lead parts and financing to make projects bankable. The government may also take a financial stake or use profit-sharing mechanisms tied to future project cash flows. That is meant to cut investor risk and attract private capital into long lead-time nuclear projects.
Chris Wright, Secretary for the United States Department of Energy, remarked:
“This historic partnership with America’s leading nuclear company will help unleash President Trump’s grand vision to fully energize America and win the global AI race. President Trump promised a renaissance of nuclear power, and now he is delivering.”
Powerful Partners: Who’s Behind the Deal
Westinghouse provides reactor designs, engineering, and project know-how. Brookfield Asset Management brings large-scale project finance and infrastructure experience.
Cameco, a major uranium producer, supplies fuel expertise and helps secure nuclear fuel supply chains. Together, they combine technology, capital, and raw material access.
The U.S. government acts as a facilitator. It will help line up financing, speed regulatory approvals, and coordinate federal support. The public role aims to reduce early-stage risk so private investors will commit to multi-billion-dollar projects. This public-private model is central to the deal.
What $80 Billion Buys: Scale and Impact
The $80 billion figure is an aggregate investment target. Industry analysts estimate this sum could support about 6 to 10 large reactors. This is based on using 1 GW-class AP1000 units and costs close to current U.S. estimates. The final mix could include several large units plus a set of SMRs, depending on site choices and supply costs.
If the program builds multiple 1 GW reactors, the added capacity could total several thousand megawatts. Each AP1000 unit can produce about 1,100 MW of electricity.
The chart shows how powerful a single AP1000 reactor is compared with other common energy sources. Each unit generates about 1,100 megawatts (MW) of electricity. That’s similar to the output of 2 modern coal plants, 5 large wind farms, or about 11 utility-scale solar farms.
Data from the U.S. Energy Information Administration, the International Energy Agency, and the National Renewable Energy Laboratory show that:
- A typical coal plant generates about 600 MW.
- Wind projects average around 200 MW.
- Solar projects average about 100 MW.
Nuclear power stands out for its ability to provide steady, large-scale electricity from one site. This supports industrial growth and helps meet clean energy goals.
Multiple units would offer steady, low-carbon power. Grid operators and large users, like data centers and manufacturing hubs, can count on this power all day and night.
Timing will depend on permitting, supply chain ramp-up, and financing. The partners said they will focus on repeatable designs to shorten schedules.
Still, observers warn that multi-year lead times are likely for most projects. The deal does include near-term actions to buy long-lead items now, which can help start work sooner.
Rebuilding America’s Energy Workforce
Backers say the program will revive large parts of the U.S. industrial base. Reactor builds need heavy forgings, turbines, valves, control systems, and large concrete works. They also need skilled trades such as welders, pipefitters, and nuclear operators.
Estimates show that there will be tens of thousands of construction jobs in peak years. Each completed plant will create thousands of long-term operations jobs.
The plan could also spur investment in domestic component manufacturing. That includes forging mills, heat exchanger factories, and specialized machining facilities.
Allied countries can also supply parts. Local content rules and incentives may boost U.S. production. Proponents say a revived supply chain will reduce cost risks and shorten delivery times over the long run.
Cameco’s shares jumped sharply when the announcement arrived. Investors expect that uranium demand will rise and prices will strengthen if a multi-reactor program moves forward.
Brookfield’s shares also rose, reflecting the firm’s role as a project owner and financier. Market moves show investor appetite for nuclear-related assets when backed by government support.
Fueling the AI Boom With Clean Power
Data centers and AI systems draw increasing electricity. International energy agencies predict that global data center electricity use may more than double by 2030. Large, always-on power sources, such as nuclear, help avoid the output variability of some renewables.
Tech firms looking to scale AI often seek firm, low-carbon power to run data centers reliably. This deal links clean power planning to industrial and digital growth goals.

Policymakers see nuclear as a way to add “firm” low-carbon capacity. The U.S. plans discussed this year aim to boost nuclear capacity significantly by mid-century. This increase will help support electrification and heavy industry. The new agreement positions Westinghouse and its owners to play a major role if the national policy push continues.
But at What Cost?
Large nuclear projects can run into delays and cost overruns. Past builds worldwide show that permitting complexity, supply chain bottlenecks, and labor shortages raise budgets and push schedules.
Critics say that scaling too quickly might cause past issues to reappear. They stress the need for tight control over management, standards, and procurement.
Cost control will matter. Industry watchers note that standardized, repeatable designs and cleared regulatory paths can reduce per-unit costs over time. The deal’s advocates point to near-term purchases of long-lead items and government risk sharing as tools to keep costs down. But the real test will come during project execution and the first wave of concrete pours and module deliveries.
On policy, the partnership came alongside broader international trade and investment talks. Some reports say allied countries, including Japan, may support financing or procurement as part of wider industrial cooperation. That could give projects added capital and technology depth, but it also means geopolitics will shape parts of the supply chain.
A Turning Point for U.S. Nuclear Energy
This $80 billion partnership is a major step toward a new U.S. nuclear building program. It pairs private capital and industry know-how with government support.
If done right, the plan could boost low-carbon electricity, create jobs, and strengthen fuel and component supply chains. If it faces delays or cost overruns, the program could strain public budgets and investor patience.
The coming months will show if the partners can turn headlines into real projects. This means getting to operating reactors that will support a low-carbon, AI-driven economy.

The accounting differences that decide whether your nature investment shows up in inventory, in BVCM, or nowhere at all.
The question reaches a procurement team about three weeks before the next sustainability committee meeting. Someone has read about insetting. Someone else has just signed off on an offset purchase. The CSO wants to know if the two are interchangeable. The answer is no, and the GHG Protocol Land Sector and Removals Standard is the reason why.
This article walks through what each term means at audit-grade specificity, what the standards actually say about how each gets counted, and how to decide which tool fits which target. The insetting vs offsetting question is one of the most-searched in corporate climate strategy, and one of the most poorly answered. By the end of this piece, you should be able to brief a committee on the difference without notes.
The two definitions, in plain English
Offsetting means buying carbon credits generated outside your value chain and retiring them against your residual emissions. The reduction happens somewhere else, financed by you, and the credit is the receipt.
Insetting means investing in emission reductions or removals inside your own value chain, typically with suppliers, where the reduction is directly linked to the products and services you buy. The reduction happens inside the boundary of your Scope 3 inventory, and the accounting treatment is fundamentally different.
The shorthand from the University of Oxford’s Nature-based Insetting Initiative is useful: insetting is what you do with the supply chain you have; offsetting is what you do with the supply chain you do not have.
What the GHG Protocol Land Sector Standard actually says
The GHG Protocol Land Sector and Removals Standard, finalised in 2024 after a multi-year pilot, sets the rules for how land-based emission reductions and removals enter corporate inventories. The Standard distinguishes between inventory accounting (Scope 1, 2, and 3) and project or intervention accounting (a separate methodology for crediting).
For insetting, the practical implication is that supplier-level interventions, when properly measured and attributed, can reduce your Scope 3 category 1 (purchased goods and services) emissions in your inventory. The reduction is not a credit retired against the inventory; it is a lower inventory number, period.
For offsetting, the credit is retired separately. It can be reported as a contribution toward a net-zero claim under the SBTi Beyond Value Chain Mitigation framework or as part of a VCMI Carbon Integrity claim, but it does not lower the inventory number.
A practical consequence: if your Science Based Target requires a 50% absolute reduction in Scope 3 emissions by 2030, insetting moves you toward the target. Offsetting does not. This single point of difference reshapes the procurement decision.
When insetting counts toward Scope 3 (and when it does not)
Insetting counts toward Scope 3 only when several conditions are met:
- The intervention must occur with an entity in your value chain.
- The emissions reduction or removal must be measured against a defensible baseline.
- The reduction must be attributed to your share of that supplier’s output, not double-counted with other buyers.
- It must follow the inventory accounting rules in the GHG Protocol Land Sector Standard, not the project accounting rules used to generate credits.
The most common failure mode is double counting. If your supplier sells the same reduction as a credit on the voluntary market and also reports it to you as a Scope 3 reduction, the math breaks. The Standard requires you to address this risk, typically by purchasing and retiring the supplier-issued credit as part of your inventory or by contractual provisions that prevent the supplier from selling the reduction twice.
When insetting does not count toward Scope 3: when the intervention sits with a supplier you do not buy from, when the baseline is not defensible, when the attribution is unclear, or when the documentation does not survive audit. Those cases default to Beyond Value Chain Mitigation, which is still useful but operates on a different ledger.
The procurement and supplier engagement question
Insetting is harder than offsetting. That is the unfashionable truth most buyers eventually confront. Offsetting is a transaction; insetting is a relationship.
To run an insetting program, you need supplier mapping precise enough to know which farms or facilities sit at which Scope 3 boundary. You need an engagement model that gets suppliers to participate, which usually requires multi-year commitments and shared economics. You need an MRV architecture that measures the right things and produces audit-ready documentation. And you need a contractual structure that prevents double counting and protects both sides.
The trade-off you receive in return is significant. Reductions count against your inventory rather than your residual. Supplier relationships deepen, which protects sourcing continuity. Yield and quality improvements often follow regenerative interventions, which reduces your input cost over time. And the regulatory file, under CSRD, CSDDD, EUDR, and the SBTi FLAG Guidance, is materially stronger.
Choosing the right tool for the right target
A practical decision rule. If your target is a science-based Scope 3 reduction and you operate in a FLAG sector or source FLAG commodities, insetting is the structurally correct tool. If your target is a net-zero claim that includes neutralising hard-to-abate residual emissions outside your value chain, BVCM via high-integrity offsets is the structurally correct tool. Most companies with material Scope 3 exposure need both, in different proportions, sequenced over time.
The sequencing matters. Insetting takes longer to stand up but produces a permanent reduction in the inventory. Offsetting can be transacted faster but does not change the inventory and now sits under tighter claim restrictions. Treat them as complementary tools with different jobs, not as substitutes. The Accountability Framework Initiative and the IUCN Global Standard for Nature-based Solutions both provide useful guardrails for the insetting side, with biodiversity, human rights, and benefit-sharing requirements that go beyond carbon math.
If you are mapping a Scope 3 reduction roadmap and need to scope which interventions count toward your inventory versus which sit in Beyond Value Chain Mitigation, the carbon and sustainability experts at Carbon Credit Capital can help you structure a nature-based supply chain investment program that fits your FLAG exposure, your target architecture, and your audit horizon. Schedule a consultation.
Net zero is often described as a balancing act: cut what you can, account for the rest, and reach zero on the ledger. That framing is useful, but it leaves something out. It treats every tonne of carbon as interchangeable and every route to zero as equally sound, while the science tells a more specific story.
Malawi has lost a striking share of its forests over the past three decades. Woodlands that once covered well over a third of the country now cover less than a quarter, and the pressure on what remains is increasing. Behind those figures sit two practical questions: what is driving the loss, and what reverses it?
