Ratings / V4-CCR
V4-CCR.
AACarbon Credit Rating, vintage-specific.
For buyers procuring credits from a specific issuance, V4-CCR rates the credit, not just the project.
What V4-CCR is
V4-CCR is a vintage-specific carbon credit rating. It assesses the integrity of a specific credit issuance from a specific year, on a AAA-to-D scale with adjustment factors.
The vintage distinction matters because a project that has performed well historically may have experienced post-issuance events that affect specific vintages. A 2021 issuance from a forestry project may carry deforestation risk from a 2022 fire that a 2023 issuance from the same project does not.
V4-CCR is the appropriate product when you are deciding whether to procure a specific lot of credits from a specific vintage year.
V4-CCR vs V4-CPR: which one do you need?
How a V4-CCR is constructed
- 01
The monitoring report and verification statement for the specific vintage are ingested and checked for completeness.
- 02
Methodology compliance is assessed against the applicable Verra VCS or Gold Standard methodology, plus V4's India-specific extensions.
- 03
Satellite data and India-specific sources are integrated: ISRO Bhuvan, FSI, CEA (for RE projects), IMD, Hansen (for forestry), NASA FIRMS (for forestry).
- 04
Field verification is conducted for the vintage-year project state, including community interviews in Hindi or regional language.
- 05
Six pillar scores are produced (0-100 each): additionality, permanence, leakage, monitoring, social safeguards, environmental safeguards.
- 06
Adjustment factors are applied where post-issuance events specifically affect this vintage.
- 07
The floor rule is applied: the final grade cannot be more than two grades above the weakest pillar.
- 08
The final letter grade is assigned and the V4-CCR report is produced.
