Project quality

What the project documents say, and where they say it

AI-assisted checks of each project’s public Verra documents against five ICVCM Core Carbon Principles: 18 yes/no questions, each “found” citing the paragraph it came from. The methodology status and the data checks are separate, deterministic lookups.

Signal, not verdict. Findings summarize evidence located in the documents. They are not a rating, a certification or an ICVCM assessment, and they can be wrong. Tested on 177 labelled questions (short excerpts), the checks were right 94% of the time.

Deterministic lookup · not AI

Read from a hand-compiled, sourced table of published ICVCM decisions (version 2026-10-15). It describes the methodology, not the individual project.

Real public project documents · sorted by overall score

Overall scores range from 58 to 89; the per-principle findings carry more information than the total. A document can evidence a principle well while ICVCM still rejects its methodology, which is why the two are shown apart.
