Small modular reactors (SMRs) are moving from concept to commercial reality. A new forecast from GlobalData suggests global SMR capacity could increase nearly sixfold between 2025 and 2030.
The projection reflects rising confidence in advanced nuclear technology as countries search for reliable, low-carbon electricity. This demand is being driven by electrification, artificial intelligence (AI), data center growth, and industrial decarbonization.
For years, SMRs were seen as a long-term idea. That view is now shifting. Governments are updating nuclear policies. Regulators are speeding up licensing reviews. Utilities are forming partnerships with technology developers.
At the same time, electricity demand is rising sharply, strengthening the case for firm power sources capable of operating 24/7. This momentum comes as countries try to meet net-zero targets while also ensuring stable and affordable energy supplies.
Why SMRs Are Gaining Momentum
SMRs are nuclear reactors that typically produce up to 300 megawatts (MW) of electricity per unit. Unlike large nuclear plants, they are designed to be built in factories and assembled on site.
Supporters say this modular approach can reduce construction time, improve cost control, and make deployment more flexible. SMRs can also be added in phases, depending on demand growth.
GlobalData’s forecast reflects a wider revival in nuclear energy. The firm expects global nuclear capacity to grow steadily over the next decade, by almost sixfold from 2025 to 2030. That increase could even reach a hundredfold by 2040. Cleaner energy goals, policy backing, and increasing demand for stable baseload electricity will support this growth.
The International Energy Agency (IEA) also expects strong long-term growth. In its Announced Pledges Scenario, the IEA predicts over 1,000 SMRs to be used worldwide by 2050. This would add up to about 120 gigawatts (GW) of capacity. It also estimates SMR investment could rise from about $5 billion today to more than $25 billion by 2030.
Meanwhile, major SMR projects are moving forward. GE Hitachi’s BWRX-300 design will be used at Ontario Power Generation’s Darlington site in Canada. This is one of the most advanced SMR projects currently in planning.
Holtec International is also advancing plans to install SMR-300 reactors at the Palisades site in Michigan. The company has outlined a long-term vision that could scale SMR capacity across North America to as much as 10 GW in the coming decades.
These early projects are important. They will test cost, speed, and performance. Their results will help determine how quickly SMRs can scale globally.
Nuclear Power’s Quiet Climate Comeback
As countries move toward net-zero targets, nuclear energy is receiving renewed attention as a low-emissions power source.
According to the IEA, nuclear is the world’s second-largest source of low-emissions electricity after hydropower. In 2024, more than 410 reactors in over 30 countries supplied about 9% of global electricity. Nuclear also generated more low-carbon electricity than wind and significantly more than solar.
- Since 1971, nuclear power has helped avoid roughly 72 gigatonnes of carbon dioxide emissions by reducing reliance on fossil fuels.
This climate contribution is becoming more important as electricity demand rises and countries retire coal plants. The IEA expects global nuclear generation to reach a record high in 2025, supported by reactor restarts in Japan, maintenance work in France, and new builds in Asia.
More than 60 reactors are currently under construction worldwide, adding over 70 GW of new capacity.
SMRs could strengthen this role further. Their smaller size makes them suitable for regions where large nuclear plants are not practical. They may also replace aging coal plants by using existing grid infrastructure.
In addition, SMRs are being considered for industrial uses such as hydrogen production, mining, and heavy manufacturing, where steady heat and power are required.
Big Tech and Data Centers Drive New Power Demand
One of the strongest drivers for SMR growth is the rapid expansion of artificial intelligence and data centers. AI systems require large amounts of electricity. Training and operating these systems depend on high-performance computing infrastructure that runs continuously. This is pushing electricity demand higher in key technology hubs.
Goldman Sachs has raised its forecast for AI-related capital spending by major hyperscalers. The bank now expects Meta, Microsoft, Amazon, and Alphabet to invest about $5.3 trillion between 2025 and 2030, up from a previous estimate of $4.5 trillion. A large share of this spending will go into AI infrastructure, data centers, and supporting energy systems.
Moreover, Goldman Sachs Research estimates global data center electricity demand could increase by as much as 165% by 2030 compared with 2023 levels.
This surge in demand is changing energy planning. While renewable energy remains central to corporate climate strategies, many technology companies are also looking for stable, round-the-clock power sources.
SMRs are increasingly viewed as a potential solution because they can provide constant power without weather dependence. Unlike wind or solar, nuclear plants can operate day and night continuously. This reliability is becoming more important as AI workloads grow and grids face higher stress.
As a result, several SMR developers are now targeting data center operators as future customers, alongside traditional utilities.
The First Wave of SMR Projects Breaks Ground
The SMR industry is now entering a more practical phase, with several flagship projects moving toward construction and deployment.
In Canada, Ontario Power Generation is advancing the first commercial deployment of GE Hitachi’s BWRX-300 reactor at the Darlington site. This project is widely seen as a key test case for SMR commercialization in North America.
In the United States, TerraPower continues development of its Natrium reactor in Wyoming. The project, backed by Bill Gates, combines nuclear generation with advanced energy storage. This design aims to improve flexibility and help balance electricity grids with growing renewable energy penetration.
These developments mark an important shift. The industry is moving beyond design and licensing discussions and into construction, financing, and real-world deployment.
The Roadblocks on the Nuclear Revival Path
Despite strong momentum, SMRs still face major challenges.
- Cost remains the most important issue. Early projects must prove that factory-based construction can reliably reduce total costs compared with traditional nuclear plants.
- Regulatory approval is another barrier. Even though licensing frameworks are improving, nuclear projects still require long review timelines in most countries.
- Fuel supply is also a concern. Many advanced SMR designs depend on high-assay low-enriched uranium (HALEU), but global supply chains are still limited.
- There are also broader concerns around nuclear waste management and public acceptance, which continue to influence project timelines in several regions.
These challenges explain why some analysts remain cautious about near-term deployment, even while long-term forecasts are becoming more positive.
Outlook: A Defining Decade for SMRs
The next five years could be decisive for SMRs. Global momentum is being driven by several overlapping trends. Electricity demand is rising. AI growth is accelerating. Countries are committing to net-zero targets. Energy security has become a national priority. At the same time, nuclear technology is improving.
GlobalData’s forecast of a nearly sixfold increase in SMR capacity by 2030 reflects growing confidence that the sector is approaching commercial scale.
While SMRs are still in the early stages of deployment, progress in Canada, the United States, China, and other regions suggests the industry is moving closer to wider adoption.
If current projects succeed, SMRs could become an important part of the global low-carbon energy mix. They may help support grid stability, reduce reliance on fossil fuels, and provide the steady power needed for a more electrified and digital economy.

Insetting program design starts with your supplier map. The carbon claim comes much later.
Consider a coffee procurement team that funds a farm intervention before checking its sourcing data. The supplier aggregates coffee lots from several regions. The buyer lacks farm-level traceability. Another purchaser expects to report the same outcome. A more attractive project brochure solves none of these problems.
If the distinction between a value-chain intervention and a purchased credit is still open, read CCC’s Insetting vs Offsetting guide before you set the brief.
Insetting program design begins with the purchasing relationship and works outward. You need to decide 1) where an intervention belongs, 2) what business problem it addresses, 3) who pays for it, 4) how results will be measured, and 5) what the evidence will let you say about them. This five-step playbook turns that sequence into a procurement plan.
Step 1: Insetting program design starts with supplier mapping
Start with the commodities that matter most to your Scope 3 inventory and sourcing continuity. Ask finance for spend by supplier, sustainability for the emissions baseline, and category managers for origin and volume records. Then identify which suppliers can trace material to a jurisdiction, sourcing region, producer group, or individual land-management unit.
The level of traceability affects what you can account for. Under the GHG Protocol Land Sector and Removals Standard, the spatial boundary for purchased land-based products depends on the traceability associated with each volume. Farm-specific factors or removals require physical traceability through an acceptable chain-of-custody model. A contract with a tier-one trader, by itself, does not establish a link to the farms behind its deliveries.[1]
Build a first-pass table with five columns: commodity and annual volume; supplier and origin; current traceability level; land-use and production risks; and the business owner who can change the purchasing terms. Mark missing data plainly. A blank cell is cheaper to fix before a program starts than after a claim is drafted.
If your company sets an SBTi Forest, Land and Agriculture target (FLAG), keep its land-related target boundary separate from energy and industry emissions. The current FLAG guidance also requires relevant companies to assess primary deforestation-linked commodities in their value chains.[2]
Step 2: Choose a commodity and jurisdiction for a pilot
Select one supply corridor where the sourcing connection can be established and procurement has a reason to stay. A useful pilot has repeat purchases, suppliers willing to share records, an intervention matched to a diagnosed problem, and a defined plan to measure the result. Carbon potential alone is a poor selection rule if the supplier cannot deliver the crop your business needs.
Compare candidate regions on land-use risk, supplier concentration, local rights and tenure, the availability of baseline data, and exposure to drought, erosion, or forest conversion. Check the relevant legal requirements separately. A nature project does not satisfy a due-diligence obligation merely because it has a carbon method attached.
Consider a coffee buyer sourcing from two districts. In the first, producer-group records identify the farms, while recent dry seasons have increased rejected green coffee lots. In the second, deliveries pass through several intermediaries and farm origins are unknown. Pilot shade management in the first district, with local agronomic advice and quality checks built into the plan. The buyer can trace purchases there and test the intervention against a defined sourcing problem.
Use a short decision memo to record why the selected corridor beats the alternatives, what remains uncertain, and what would stop the pilot. That memo is the first control against a project drifting toward whatever happens to photograph well.
Step 3: Design the supplier engagement and commercial model
The intervention needs an owner on each side of the contract. Decide who supplies planting material or training, who maintains the practice, who bears the cost if a harvest disappoints, and how long the buyer expects to purchase from participating suppliers. Where smallholders participate, budget cash flow and technical support for practices that offer a later return.
Put these terms in a supplier agreement or pilot addendum. It should cover eligible farms and volumes, consent to data collection, access for monitoring, any land or carbon rights that matter, benefit sharing, and what happens if the purchasing relationship ends. Ask local counsel and producer representatives to review the arrangement. The Accountability Framework is a useful reference for supply-chain work involving forests, ecosystems, and human rights.[3]
Avoid assigning an automatic carbon benefit to the buyer. The contract should say which party has the right to report each outcome, how overlapping claims will be checked, and how any issued credits will be handled. A reduction reported in a buyer’s inventory cannot simply be sold for someone else’s offset claim without an accounting review. SBTi FLAG guidance excludes purchased credits used as offsets from near-term FLAG target achievement.[2]
Set commercial measures beside environmental ones: delivered volume, rejection rate, supplier retention, and procurement cost. They tell you whether the program works as a supply-chain investment, even if carbon accounting takes longer to resolve.
Step 4: Build monitoring, reporting, and verification before rollout
Agree on the baseline and data flow before paying for a full rollout. Identify the land units or sourcing regions in scope, the practices that change, the records suppliers already keep, and the additional measurements the program requires. Decide which data can come from field visits, transaction records, or remote sensing, and who checks each source.
For carbon, separate three questions. Did the practice happen? Did emissions or removals change under an applicable method? Can the buyer attribute a defensible share to its purchased goods without double counting? The GHG Protocol’s 2026 guidance includes dedicated chapters on spatial boundaries, data and methods, evaluating actions, credited outcomes, and assurance.[1] These are distinct jobs. A photograph of a planted tree answers only part of the first.
CCC’s MRV and Additionality article explains the separate evidence questions a project reviewer will ask.
Create an evidence file for every reporting period: dated supplier and farm records, purchase volumes, methods and emission factors, uncertainty, quality checks, and changes from the baseline. Specify who can challenge the data and how corrections are recorded. If a project also seeks credit certification, keep project accounting and corporate inventory accounting separate. The GHG Protocol says its land standard focuses on entity-level inventories and does not set the rules for credit certification.[4]
Start with the minimum viable measurement design that can survive review. Add complexity when the pilot tells you which data actually changes a decision.
Step 5: Decide what can be reported and claimed
Insetting program design needs reporting rules before the marketing copy. Procurement, sustainability, finance, and legal should agree on four distinct outputs: operational performance; observed land or nature outcomes; inventory effects, if the accounting criteria are met; and any separately issued credits. One dashboard can display them, but they should not share a single unqualified headline.
SBTi FLAG guidance allows certain land-based removals within a company’s operations or supply chain to contribute to FLAG pathways, subject to criteria including permanence, traceability, data quality, and allocation. It does not allow purchased offsets to meet near-term FLAG targets.[2] Eligibility therefore depends on evidence and the applicable target rules, not on calling an activity “insetting.”
Draft a claims register. For each proposed sentence, record the period, boundary, data owner, calculation method, reviewer, and whether the result is measured, estimated, or still a goal. If the evidence supports only “we funded a pilot with 200 farms,” say that. Do not turn a funding fact into a verified emissions reduction.
What good looks like by year three
Treat year three as a review point, not a promised payback date. A mature pilot should have mapped participating supply volumes, a stable supplier agreement, a repeatable data collection process, and a comparison of commercial and environmental results against the baseline. It should also have a documented answer for outcomes that cannot be included in the buyer’s inventory.
Scale only where the pilot improves a sourcing decision and the evidence can follow the product. If neither condition holds, redesign the intervention or change the corridor. A disciplined program can conclude that a site is unsuitable. That is useful procurement intelligence.

Nature-based carbon investments deserve consideration when they address a specific business dependency and produce outcomes you can measure. Imagine Moonbucks, a global coffee roaster planning next season’s espresso blend. It is considering natural Grade 4 coffee from Jimma, in southwestern Oromia, Ethiopia. Its sourcing decisions affect the roasting schedule and the cash tied up in coffee purchases. Moonbucks needs to understand which measures could protect that supply, what they would cost and how it would judge the results.
1. Define the sourcing problem before choosing a project
Moonbucks needs a dependable component for its espresso blend. Its procurement team wants continuity of volume and an agreed cup profile. Replacing a shipment at short notice could require new sample approval and changes to the blend, and given the schedules for cultivation, processing, and freight delivery, is practically impossible. Moonbucks needs to get this right, and its initial concern is inconsistent deliveries. It commissions an assessment of the supplying farms and post-harvest chain. The questions cover land condition, harvest availability and whether drying or storage problems are affecting saleable lots.
This distinction changes the investment brief. A tree-planting proposal cannot be assumed to fix drying problems. Better storage cannot restore eroded land. The team must establish which problem exists before selecting the response.
CCC’s guide to finding nature-based solutions in your supply chain explains where to look. Here, the next task is to turn a broad concern into a testable proposal.
2. Develop nature-based carbon investments around the actual supply chain
The assessment would trace Moonbucks’ purchases back through the exporter and supplying producer groups. Which farms supply the contracted lots? Who controls land-management decisions? How long does the buyer expect to maintain the purchasing relationship?
Furthermore, Jimma natural Grade 4 cannot be treated as interchangeable with every Ethiopian coffee. Moonbucks would need to test any substitute against its own blend and quality requirements.
Suppose Moonbucks’ assessment identifies an opportunity to maintain shade trees and restore vegetation along exposed streambanks. The IPCC describes agroforestry as a way to store carbon in vegetation and soil, with potential benefits for erosion control and water quality.1 Moonbucks would need local advice on species, growing conditions and maintenance before deciding how these measures fit its sourcing plan.
The proposal now has a defined sourcing connection and a candidate intervention. The next steps are to test its effect on production, assess carbon eligibility and build the financial case.
3. Compare the proposal with other ways to protect supply
WBCSD’s Nature-based Solutions Blueprint recommends comparing nature-based options with other responses across their benefits and costs.2 For Moonbucks, that means evaluating the landscape proposal alongside drying improvements, storage controls and alternative sourcing arrangements.
The product’s natural-process designation matters. Moonbucks should examine the drying and dry-milling chain alongside land conditions. Its team would check storage practices, contamination risks and incoming-lot quality to see whether problems arise before or after the coffee leaves the farms.
The revised proposal might combine land stewardship with separate post-harvest controls. Each component needs its own purpose and budget. A sustainability label should not obscure which activity is expected to solve which problem.
The project develops as the evidence improves. Its scope should follow the diagnosis rather than preserve the first idea unchanged.
4. Establish what the carbon outcome could count toward
Moonbucks’ sustainability team now tests the proposed carbon case separately from the sourcing case. Is the objective a measurable change in Moonbucks’ value-chain emissions, verified credits for separate voluntary use, or distinct outcomes under carefully defined arrangements?
Scope 3 covers value-chain emissions. A purchasing relationship alone does not prove that a farm intervention can be included in Moonbucks’ inventory. The team needs an applicable accounting method, defensible boundaries and evidence supporting attribution.
SBTi’s FLAG Guidance (forest, land and agriculture), version 1.2, says purchased credits used as offsets cannot meet near-term FLAG or energy and industry targets. Eligible land-based removals are subject to accounting requirements.3 Moonbucks needs to test its proposal against those rules before including an outcome in its targets.
For Moonbucks’ Jimma proposal, maintaining existing trees and establishing new vegetation could involve different carbon questions. Specialists must examine the baseline and additionality, meaning what changes because the project proceeds. They must also assess measurement and the risk that stored carbon is lost. CCC’s MRV and additionality article introduces those tests.
Until that work is complete, Moonbucks should not budget an assumed Scope 3 reduction or credit-sale receipt. Direct emissions reductions remain the priority.
5. Build a financial case that survives weaker assumptions
Moonbucks’ finance team would now build a multi-year budget. UNEP’s State of Finance for Nature 2023 compares current finance with the investment needed to meet climate, biodiversity and land-restoration goals.4 The company would cost its proposed activities, farmer participation and ongoing monitoring. Verification, where required, is a separate expense. Maintenance and responsibility for replacing failed plantings must remain visible after the initial establishment budget ends.
Operational benefits need equally careful treatment. If fewer rejected lots reduce emergency purchasing, count that saving once. Do not add “supply resilience” as another financial benefit when it represents the same avoided cost.
Moonbucks should compare a base case with slower benefits, higher implementation costs and no carbon revenue. It should also distinguish production outcomes from quality and shipment outcomes. A single good harvest would not prove that the landscape intervention caused better delivery performance.
A project can remain worth funding even when its carbon case needs more work. That decision must rest on the operational evidence and the company’s objectives, without unsupported environmental claims.
6. Fund a pilot with a clear expansion decision
Moonbucks’ first approval would fund a bounded pilot, rather than commit the entire sourcing program. Before spending, Moonbucks would agree on participating farms, responsibilities and the evidence needed at review.
Its scorecard could track farmer participation, implementation costs and plant survival, alongside accepted coffee volumes and lot-quality results. Carbon measurements would follow the selected method. Farm-level traceability must connect the intervention to the actual sourcing relationship.
Suppose Moonbucks’ review later finds that storage changes explain most quality improvements, while the land measures need longer observation. Those findings would shape the next decision: expand the proven component, adjust the landscape work or pause further spending. They would not justify crediting all improvements to tree planting.
This gives nature-based carbon investments a practical place in a multi-year strategy. Funding increases as the evidence supports it, and the project can change direction before a larger commitment.
