Integrity Scoring: How Carbon Credit Quality Becomes a Rating

Integrity scoring is a structured method that converts evidence about a credit's additionality, measurement, permanence and safeguards into a comparable rating, so that projects of different types can be assessed on a common footing. It sits inside Carbon Credits and connects directly to how projects are documented, financed, and judged.

A scoring model defines indicators for each quality dimension, assigns weights, and grades the evidence supplied for a project. Scores are then aggregated into a band, with critical indicators able to cap the result. The output is published with the underlying evidence so that a reader can trace how the band was reached. Ratings are also versioned, so a buyer can see whether a band was earned under the current model or an older one, and whether new evidence later changed it.

Scores let buyers screen large portfolios quickly and let developers see which weaknesses cost them most. A transparent scoring method also disciplines the market, because a rating that can be traced to documents is harder to inflate than a marketing claim. In practice, a score is most useful when it is compared across a shortlist of projects assessed by the same method, since scores from different models are not directly interchangeable. Clarity about Integrity scoring is what lets buyers, sellers, and regulators compare like with like instead of trading on assumption.

Practical experience with Integrity scoring tends to reward patience and discipline: the organisations that document their assumptions, keep an audit trail, and revisit their methods are the ones that keep credibility when questions are asked.

Weightings embed judgement, and a model can be tuned until almost anything scores well. Aggregation can also hide a fatal flaw, so a high band on a credit with unresolved land tenure is misleading. Scores must be read alongside the evidence, never instead of it. A further problem is that a high score on a small project can be read as a guarantee when the sample behind it was thin.

CarbonFi's integrity layer produces a scored assessment from Athlas Verity evidence and stores the score plus its inputs next to the credit on-chain, so the rating travels with the asset and can be re-checked by any buyer. For teams working across CarbonFi, Integrity scoring is not abstract: it maps onto concrete steps in verification, issuance, trading, or retirement, each of which can be recorded and checked on-chain.
