Investors and climate leaders are increasingly exploring how blockchain can modernize the voluntary carbon market. Circle Internet Group (NYSE: CRCL), the issuer of the USDC stablecoin, plays a pivotal role in this transformation. With its trusted infrastructure, Circle makes tokenized carbon credits more transparent and accessible.
A recent surge in CRCL stock at over 20%—sparked by U.S. stablecoin legislation—highlights growing interest in ESG-aligned blockchain firms. This article looks at how Circle uses stablecoins and blockchain for digital climate solutions.
Carbon Credits Meet Blockchain: What Are Tokenized Credits?
Carbon credits are certificates representing the reduction or removal of one metric ton of CO₂. Companies buy these to reduce emissions. They support verified projects like reforestation, methane capture, or renewable energy.
Tokenization puts carbon credits on the blockchain as digital tokens. This method delivers several key benefits:
- Transparency & traceability: Each token records its origin, audit trail, and retirement status on a public ledger, reducing fraud and double-counting.
- Liquidity & access: Tokens are divisible and tradable 24/7. Smaller buyers can own portions of a carbon credit, expanding participation.
- Lower costs: Blockchain automates transfers and records through smart contracts, cutting fees and administration time.
Experts expect the voluntary carbon market to reach over $100 billion by 2030, driven partly by tokenization. Blockchain also bridges traditional registries—like Verra and Gold Standard—to digital ecosystems.
Circle Internet’s Role in Blockchain Climate Infrastructure
Circle, started in 2013 by Jeremy Allaire and Sean Neville, is famous for USDC. This stablecoin is pegged to the dollar and works with many blockchains, like Ethereum, Solana, and Avalanche.
Circle uses its strong ties to regulated finance to offer reliable support for the new era of climate finance. But the company’s role goes beyond payments—it’s actively building the foundation for tokenized carbon markets.
Key Contributions to Tokenized Carbon Markets
Stable, programmable currency for carbon markets. USDC acts as a bridge between traditional fiat currencies and blockchain-based carbon trading platforms. Projects can use USDC to denominate carbon credits. This boosts liquidity and makes it easier for institutional buyers to access them.
Regulatory-grade transparency. Circle regularly checks its dollar reserves with top auditing firms. It also has licenses in almost every U.S. state. This transparency builds trust in carbon credit transactions, which is crucial in an industry criticized for greenwashing and double-counting.
Support for open carbon infrastructure. Circle has teamed up with Toucan Protocol, a network that is among the largest for tokenized carbon credits. Together, they will help retire and redeem credits on-chain.
Toucan launched Base Carbon Tonne (BCT) tokens in 2021, with USDC as the default settlement currency. Circle’s blockchain rails help make this system scalable and interoperable.
Investment in ReFi (Regenerative Finance). Circle Ventures, the venture arm of the company, has supported many startups. These startups focus on blockchain applications that are climate-positive. This includes support for protocols that tokenize real-world assets (RWAs). These assets are things like renewable energy credits, biodiversity outcomes, and reforestation efforts.
Partnerships and Climate-Tech Ecosystem Involvement
- KlimaDAO Integration: Circle works with KlimaDAO, a decentralized group focused on making carbon markets clear and efficient. KlimaDAO brings together tokenized credits like BCT and NCT (Nature Carbon Tonnes). It helps with trading and retiring these credits using USDC.
- Celo Alliance for Prosperity: Circle is in the Celo Alliance, a group that has more than 150 companies. They all work together to create a carbon-negative blockchain ecosystem. USDC on Celo supports climate apps. These apps reward users for eco-friendly actions, like planting trees and adopting clean cooking in developing countries.
- Support for Real-Time ESG Reporting: Circle’s programmable payments and on-chain transaction history make it easy to connect with ESG reporting platforms. Firms buying tokenized carbon credits with USDC can automate tracking. They can also link emissions ledgers and guarantee complete auditability.
A Bold Vision for Digital Climate Finance
In interviews and public statements, CEO Jeremy Allaire has emphasized that tokenized environmental assets like carbon credits represent a “new frontier for digital finance”. It has massive potential to align capital flows with sustainability goals.
Circle supports climate action using its blockchain and stablecoin, USDC. The company hasn’t shared specific goals for net-zero operations or interim emissions cuts. Still, it focuses on transparency, following regulations, and innovating in digital climate finance.
Circle’s sustainability initiatives are focused on:
-
Building and scaling the blockchain infrastructure for digital climate finance.
-
Supporting and investing in the ecosystem of projects that tokenize carbon credits and promote transparent climate action on-chain.
-
Delivering compliance and developer tools for sustainable finance applications.
Circle itself does not run direct environmental projects. However, it acts as a critical enabler of digital sustainability solutions through its technology and partnerships. It connects traditional finance with new tokenized marketplaces. As such, let’s explore one specific example of a tokenized carbon credit.
MOSS.Earth: Real Conservation, Real Impact, Real-Time on Chain
Moss Carbon Credit (MCO₂) is a good example of tokenized carbon in action. Managed by Brazilian climate-tech firm MOSS.Earth, MCO₂ links each token to a forest-based carbon credit verified under global standards.
- How it works: Token holders can retire MCO₂ to claim one tonne of CO₂ offset. Every transaction is logged on the blockchain for public verification.
- Why blockchain: Tokenization ensures every credit is unique and immutable. Moss has funded roughly $15 million in Amazon conservation over a single year.
- Intersection with Circle: USDC is the main payment method on MCO₂ platforms. It offers quick and secure settlements, which boost market efficiency.
This case shows how Circle’s secure payment rails help make a real environmental impact through decentralized platforms.
Why This Crypto Sector is Set to Boom
The stablecoin sector is booming in 2025. This growth comes from strong support from institutions, clearer rules, and more uses in global payments and finance. Leading stablecoins like USDC and USDT dominate, while new fiat-backed coins tied to the euro and Swiss franc emerge.
Market forecasts expect stablecoin circulation to rise from about $230 billion today to over $2 trillion by 2028. Stablecoins help make cross-border payments faster and cheaper. They also boost financial inclusion. These coins connect crypto with networks like Visa and Mastercard.
More notably, regulatory efforts in the U.S. are helping to bring stablecoins into the traditional financial system. This seems to be the case with the recently approved law that boosts this digital currency.
The GENIUS Act Effect: What It Means for CRCL Investors
On June 17, the U.S. Senate passed the GENIUS Act (Guiding Uniform and Innovative Stablecoin Standards). This bipartisan law sets reserve standards and transparency rules for consumer-focused stablecoins, like USDC. It aims to boost innovation and protect public trust.
The impact on Circle was immediate:
- CRCL stock surged: Shares jumped ~16–27% after the Senate vote, climbing from $31 to over $190.
- Investor confidence soared: A boost from ARK Invest and positive analyst coverage drove CRCL close to $260. This reflects hopes that USDC could become mainstream financial infrastructure.
The GENIUS Act underpins USDC’s credibility and boosts its role in ESG fintech. Regulatory approval makes Circle a safer partner for banks, governments, and climate technology platforms.
What’s Next for Blockchain & Transparent Carbon Markets?
Tokenized carbon credits offer a powerful path to transparency and inclusivity in climate finance. Circle offers stable, regulated rails and thus, blockchain ecosystems like Moss and Toucan can scale efficiently. Yet, risks remain, such as:
- Greenwashing: Not all tokenized credits guarantee real-world emissions reductions.
- Project quality: Credits depend on transparent environmental verification and monitoring.
Blockchain’s public audit trail reduces these risks. It makes retirements and project data visible and unchangeable. Circle is well-positioned to lead in this space.
As regulators embrace stablecoin frameworks and carbon tokenization becomes mainstream, Circle’s USDC infrastructure may underpin much of the climate fintech ecosystem.
By powering transparent, digital carbon trading and gaining regulatory support via the GENIUS Act, CRCL stock underlines investor confidence in blockchain’s role in climate solutions. This places the company in a great spot where finance, tech, and sustainability come together on the blockchain.

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?
