Moody’s for carbon

Which carbon credits are real?

CarbonDecode rates every project in the voluntary carbon market on a transparent, audit-ready integrity scale, then reads the documents, the news, and the satellites to back the rating up.

11,521 projects rated · 78.4% investment-grade

Market is mostly junk.

Roughly 84% of voluntary carbon credits are high-risk, and only about 8% carry an ICVCM Core Carbon Principles label. Investment-grade credits trade at a large premium to the rest.

Buyers, brokers, auditors, and (under the EU’s Empowering Consumers Directive) marketers now need defensible, auditable evidence that a credit represents a real tonne. CarbonDecode is that evidence: a rating you can defend line-by-line, plus the primary documents, news, and Earth-observation behind it.
