Document-based rating

3.6/10

Low rating (3.5 to 4.9)

Evidence coverage: high

How solid the credit is, as far as the registry's public documents show. Additionality and quantification start from a public grade; permanence starts at 5.0, the neutral point, where none applies, and claim safety always does.

Methodology v3 · documents read on 16 Oct 2026

Starting point

  • Additionality: the ICVCM's decision on this methodology
  • Quantification: the ICVCM's decision on this methodology
  • Claim safety: neutral (5.0) — no public grade of this type of project applies

Rules that raised the number: 1

Rules that lowered the number: 2

Each rule, with the fact and the source it rests on, is in the Premium analysis.
