The voluntary carbon market made great strides in early 2025. strong growth. This is fueled by record credit retirements, a focus on integrity, and increased interest in carbon removals compared to traditional avoidance credits.
We have studied newly published reports from two credible research agencies, namely Sylvera and CEEZER. Both say that organizations are now willing to invest more in credits that deliver real climate impact. Thus, the market is shifting from quantity to quality, and the numbers support this. Let’s deep dive.
Carbon Credit Retirements Reach a New Peak
Carbon credit retirements hit 95 million in the first six months of 2025, the highest total ever recorded for a half-year. This marks a 9% increase compared to H1 2024. More importantly, total retirement value jumped by 32%, indicating that buyers are not just retiring more credits—they’re paying more for the right ones.
This increase reflects a clear preference for verified high-quality credits. Buyers are becoming more selective and placing climate integrity at the forefront.
Supply is Growing, But Demand Is Growing Faster
On the supply side, carbon credit issuances rose to 77 million in Q2 2025, a 39% increase from the previous quarter. This represents a 14% boost compared to Q2 2024.
Yet even with more credits available, retirements continue to outpace issuances. If this trend holds, this year could see negative net issuance for the first time. However, this imbalance can inevitably put pressure on developers to meet demand for high-integrity credits. As companies pursue long-term climate targets, they seek more than low-cost offsets.
Quality Becomes a Core Priority
Data shows buyers are moving up the quality ladder. In H1 2025, 57% of Sylvera-rated credits retired had BB ratings or higher, up from 52% in all of 2024. This shift is driven by better due diligence tools, clearer carbon credit ratings, and initiatives like the ICVCM’s Core Carbon Principles.
Market participants are becoming more informed and aligning purchases with ESG goals, climate science, and regulations. Buyers now choose credits with intention instead of blindly purchasing.
CORSIA Spurs Growth in Compliance-Eligible Credits
The Sylvera report further emphasizes that more than 37% of credits issued in Q2 2025 could be eligible under Phase 1 of CORSIA, the global offsetting scheme for international aviation.
- This is a notable increase from 28% in the same period of 2024. This alignment with international standards is closing the gap between voluntary and compliance markets.
Full CORSIA eligibility depends on host country authorizations under Article 6 of the Paris Agreement. The cancellation deadline for Phase 1 is January 2028, and developers are closely watching national authorities’ responses.
The Market Shifts Toward Durable Carbon Removals
One key trend of 2025 is the strong shift toward carbon removals. CEEZER data shows a 102% increase in the share of removal credits transacted compared to last year. Buyers are prioritizing long-term impact over short-term avoidance.
Spending patterns reflect this shift. The average spend per ton across all credit types has more than doubled, rising 2.2 times year-on-year. For removals specifically, prices have increased by 3.2 times. This premium reflects interest in projects with lasting impact, such as biochar, mineralization, and reforestation.
Companies are now focusing on credits in Oxford Category 5, representing durable removals with low reversal risk, rather than Category 4 credits, which carry higher long-term uncertainties.
Nature-Based Credits in Demand, But Supply and Standards Remain a Challenge
Nature-based projects like ARR (Afforestation, Reforestation, and Revegetation) are attracting premium prices. On average, ARR credits are selling for $24 per ton in the primary market. For credits with BBB+ ratings, prices can reach up to $27. However, these credits only make up 3.7% of total retirements, indicating high demand but limited supply.
This supply-demand gap is prompting developers to increase high-quality nature-based removal projects. However, challenges like land access, cost, and long verification timelines still hinder expansion.
Moving on, REDD+ projects, aimed at reducing deforestation and forest degradation, rebounded in Q2 2025. Their share rose from 3% in Q1 to 16%, the highest since Q2 2023. Still, scrutiny remains over outdated REDD+ methodologies, many of which may not meet ICVCM’s integrity standards.
This uncertainty is pushing buyers to explore alternatives like waste management, biogas, and improved forest management, where credibility and transparency are easier to achieve.
North America Leads Issuance Growth
Significantly, North America has become a major player in carbon markets, doubling its share of new issuances to 43% in Q2 2025. This growth propelled the American Carbon Registry (ACR) to the top spot among registries, holding a 33% share. Gold Standard followed at 25%, and Verra at 21%.
This surge reflects stronger project pipelines, clearer regulations, and confidence in the U.S. market’s ability to meet both voluntary and compliance criteria.
Industrial and Commercial Credits Gain Market Share
Carbon credit projects from industrial and commercial sectors are quickly gaining traction. In H1 2025, these projects accounted for 19% of new issuances, up from just 7.9% during the same time in 2024. These include initiatives like refrigerant recovery, methane capture, and energy efficiency upgrades.
These scalable, technology-driven projects are becoming popular alternatives to traditional forestry and land use projects. As demand grows, industrial credits are expected to capture a larger share of the market.
Tech and Services Drive Up Carbon Removal Demand
The CEEZER report also highlighted that professional services and tech sectors are emerging as key players in carbon removal. Professional services firms now account for 24% of the total retirement value in 2025. The tech and IT sector has seen a 61% jump in retirement value for removals, the highest growth rate of any sector this year.
These industries align decarbonization with business values, helping shape the next phase of the market.
Greenhushing Begins to Decline
Many companies used to quietly retire credits. This trend is known as “greenhushing.” However, things are changing. CEEZER’s Greenhushing Index tracks these anonymous retirements. It peaked at 42% during the 2024 U.S. elections. By Q1 2025, it fell to 35% and then to 23% in Q2.
This decline indicates growing buyer confidence. Companies are becoming more transparent, using credit retirements to showcase their climate leadership.
So, Is Integrity the New Standard for the Carbon Market?
Data from H1 2025 shows the carbon market is growing. Buyers are now focusing on credits that offer long-term benefits instead of offsets. With PACM credits coming later this year and high-integrity standards becoming standard, 2025 could establish new benchmarks for credibility and performance.
As demand and quality expectations increase, developers and registries will feel more pressure to deliver. The voluntary carbon market is aligning more with compliance markets. It is becoming a key tool for global climate action.
Allister Furey, CEO at Sylvera, summarized:
“Demand for credits and, in particular, high-quality credits is at an all-time high. At the same time, increasing use of project-based credits in compliance schemes is narrowing the gap between voluntary and compliance markets. Meeting both higher climate integrity standards, as evidenced by ratings, and eligibility criteria for schemes, like CORSIA, is being seen as essential for new projects in development. Market alignment with both integrity and regulatory expectations is starting to unlock the potential of carbon markets to deliver genuine climate impact at lower economic costs.”
If this trend continues, 2025 won’t just break records; it could redefine how the world values the carbon removal market.
The post Carbon Removal in 2025: Are You Investing in the Right Climate Credits? appeared first on Carbon Credits.
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?
