Double counting vs double claiming: the two risks that are often confused
The first thing to get right is the terminology. In carbon markets, the problem is not only who buys a credit. The real issue is whether the same climate outcome is recorded, sold, or claimed more than once across different chains.
Double issuance means the same reduction or removal is issued as more than one credit. Double use means the same credit is used more than once. Double claiming means different parties make climate claims on the same underlying result, even if only one credit was issued. Double counting is the broader umbrella term, and it often gets used loosely to cover all of these risks.
That distinction matters for buyers because the risk matrix changes with the final claim. Offsetting, carbon neutral, insetting, Scope 3 contribution claim, and product-level climate claim all require different levels of proof, different registry treatment, and different retirement logic.
A simple example shows why. A credit from an agricultural project can be validly issued and retired. But if the project developer, the downstream food distributor, and the retailer all use that same project to support a climate statement, the problem is double claiming even without double issuance.
This is why integrity frameworks now focus on controls that prevent reuse after retirement. The ICVCM Core Carbon Principles require checks on no double issuance and registry provisions that stop further transfers or retirements once a unit has been retired.
Agricultural chains make this harder, not easier. Ownership, land rights, and custody are often fragmented, so the most expensive disputes usually start there.
Why agricultural credits are especially exposed to accounting and ownership disputes
Agricultural credits are exposed because the underlying asset is often diffuse, reversible, and multi-actor. The land may involve owners, tenants, cooperatives, upstream buyers, downstream buyers, and sometimes public subsidies or territorial programs that support the same practice change.
That is true across soil carbon, regenerative agriculture, and agroforestry credits, but the risk profile is not identical. For soil carbon and many regenerative agriculture projects, the key issues are baseline setting, sampling, and model quality. For agroforestry, biomass enters the picture too, along with tenure and rights over trees. A 2025 meta-analysis confirms that agroforestry can increase soil carbon sequestration, but geographic variability remains high.
The market data also show why this segment is getting more attention. In projects under the French Label Bas-Carbone, I4CE notes that agricultural projects tend to be collective, larger in scale, and often based on large farms. It also reports that validated potential supply reached about 2.8 MtCO2eq in 2024, roughly double 2023.
The legal vulnerability is straightforward. Without clauses on title to carbon, rights to emission reductions, and responsibility if credits are invalidated, the same result can be contested by the landlord, operator, project developer, or offtaker.
That does not mean the problem is systemic in every case. It means the market needs a better read on what is structural and what is just fear. That is where the I4CE analysis is useful.
What the I4CE analysis suggests about the real scale of the problem
I4CE takes a more measured view than the social-media debate. Its position is that double counting is real, but it is not always so large that it blocks cooperation, especially when claims, accounting, and registry treatment are clearly separated.
That nuance matters because the policy and market context is still evolving. I4CE is working on carbon certification, carbon farming, and projects such as CREDIBLE and CAFAMORE precisely because common rules are still being built and the market wants a shared basis for credibility and scale.
The supply side is also becoming more visible. In the French case, expansion of validated supply suggests the market is becoming more institutionalized. At the same time, more supply makes accounting errors easier to spot, especially when the same project is used both for climate finance and for commercial storytelling.
For buyers, the key distinction is practical. I4CE and other analysts separate accounting between entities or countries from commercial claims. The first may require registry corrections or, in some cases, corresponding adjustments. The second is about governance, contract language, and marketing discipline.
So the question is not whether the risk exists. It does. The question is how to check a soil, regenerative, or agroforestry credit before buying it.
How buyers can assess whether soil, regenerative, and agroforestry credits are safe to purchase
Buyers should use a layered due diligence process. Start with registry retirement, serial number traceability, methodology review, MRV design, permanence buffer, leakage assessment, and proof that the seller has exclusive rights to generate and sell the credits.
Ask the vendor for evidence of no double issuance. Ask whether the same practice change is also funded by subsidies or other programs. Ask for a clear map of the claims that are allowed: offset, contribution, insetting, product claim, or scope-based disclosure.
For soil carbon credits, safety depends heavily on conservative baselines and data quality. Buyers should check soil sampling design, sequestration models, monitoring frequency, and how reversal risk is handled before signing.
For agroforestry credits, the legal checklist is even more important. Buyers should verify ownership of trees, rights to timber, tenure over the land, and anti-contestation clauses if the project involves cooperatives, tenant farmers, or mixed land-use systems.
The broader market trend supports this focus on quality. In 2025, the voluntary carbon market continues to move toward nature-based solutions and removals, but buyers are judging quality more on interoperability, integrity, and claim discipline than on volume alone.
Due diligence helps, but it is not enough by itself. Without strong contracts and registry language, the protection is still incomplete.
What project developers and investors should build into contracts, registries, and claims language
Contracts should spell out title, exclusivity, transferability, retirement, invalidation, replacement credits, and liability if double issuance or double claiming occurs.
Registries should act as the single source of truth. A unique unit ID, an audit trail, cancellation after retirement, and restrictions on reuse are now basic best practice in integrity frameworks.
Investors should treat this as more than a reputational issue. A dispute can block offtake agreements, delay cash flow, and reduce the realized price per ton, especially in nature-based portfolios.
Claims language also needs clear boundaries. If the buyer wants to use credits for a carbon neutral claim, the contract should define the communicable perimeter. If the project is sold as a climate contribution, the language should prevent overstated offsetting claims.
The regulatory direction is also moving toward more traceability. Article 6 procedures and registry-based accounting are pushing the market toward stronger authorization logic, so contracts should already anticipate that level of discipline.
When contracts, registries, and claims language line up, the conversation changes. It moves from avoiding mistakes to unlocking institutional demand.
Why clearer rules could unlock more confidence in nature-based carbon markets
Clearer rules on double counting, corresponding adjustments, claims taxonomy, and registry interoperability would reduce commercial friction and lower due diligence costs for global buyers.
That matters because nature-based markets attract demand for a reason. They combine climate, biodiversity, and soil health co-benefits. But institutional buyers usually enter only when the claim framework is clear enough to trust.
The Label Bas-Carbone and the work around it show the point well. Robust certification frameworks can catalyze private investment when the label is recognizable and the risk of duplication is low.
For buyers, the implication is simple. More clarity means less legal work, fewer price discounts for serious operators, and better bankability for developers and land managers.
If voluntary standards, Article 6 accounting, and corporate claims guidance keep converging, agricultural credits can move from controversial assets to more reliable climate finance instruments.
