Carbon credit intelligence
Independent rating agencies now grade carbon credits the way credit-rating agencies grade bonds.
Understanding what sits behind a rating is the difference between buying real abatement and buying paper.
A carbon credit rating is an independent judgement of how likely it is that one credit represents one real, additional, durable tonne of CO₂e avoided or removed.
Agencies reach that judgement by scoring a common set of risk factors:
Would the emissions reduction have happened anyway, without the credit revenue? Projects that fail this test are over-credited from day one.
Will the carbon stay stored? Forestry and soil projects carry reversal risk from fire, disease and land-use change that engineered removals largely avoid.
Was the counterfactual baseline realistic? Inflated baselines are the most common driver of over-crediting findings across rated projects.
Did the protected activity simply move elsewhere — deforestation displaced to the next valley rather than avoided?
Additionality, carbon accounting and non-permanence. Deliberately forgoes trading, project development and MRV consulting to avoid conflicts of interest.
Carbon accounting, permanence and co-benefits, assessed against frameworks built per project type (REDD+, ARR, cookstoves and so on).
Additionality, baseline crediting, project emissions, leakage, permanence and overlapping claims.
A rating is a screen, not a price.
It answers whether a credit is likely to represent a real, additional, durable tonne — a question worth asking before purchase rather than after.
This page does not track or quote what any credit costs; the agencies’ own published methodologies are the primary source for what a rating measures.
What each agency actually scores when it reaches a rating — additionality, baseline and over-crediting, permanence and leakage — is covered in more depth, agency by agency, in carbon credit risk analysis.
Ratings are a screen, not a substitute for diligence.
A credible buying process pairs an agency rating with the integrity benchmarks the market now expects — the ICVCM Core Carbon Principles on the supply side and, in the UK, CMA Green Claims scrutiny of how the purchase is described.
Remember the reporting rule that surprises buyers: offsets never reduce the gross Scope 1–3 emissions you report under SECR or UK SRS S2 — gross emissions and credits are disclosed separately, which is the point at which a rating meets sustainability reporting in practice.
Specialist carbon neutral consultants can structure claims correctly, and the carbon offset consultant guide on uksrs.org.uk covers the mitigation hierarchy in full.
For the disclosure side, see the UK sustainability reporting standards reference.
For how that gross-accounting rule and the UK SRS S2 disclosure interact with CSRD and the CMA Green Claims Code, see carbon credits in sustainability reporting.
SRS Credit provides independent carbon credit risk analysis across rated and unrated projects.
