Rigour without compromise
Every rating backed by science and evidence.
Our internal evaluation standards draw on peer-reviewed science, established carbon accounting practice, and independent evidence review. We apply consistent criteria to every credit, regardless of developer or registry.
Evidence-led review
Ratings based on documentation, not promises.
Valence Four reviews issuance records, monitoring reports, verification statements, registry documentation, and project evidence to build a clear view of credit quality.
Clarity that moves markets
Ratings that buyers, sellers, and regulators trust.
From AAA to D, our rating scale provides a clear, consistent signal about carbon credit quality. Buyers use our ratings to make informed procurement decisions. Developers use them to demonstrate quality. Regulators use them to set standards.
Built for every participant in the carbon market
Carbon markets need a shared language for quality. Valence Four is designed to help different participants read the same credit evidence and make better decisions from it.

Evaluate credits before purchase. Avoid greenwashing.
Use ratings to compare credit quality, spot weak documentation, and support procurement decisions with a consistent signal.
For Developers
Benchmark your project. Signal quality to the market.
Use the review process to understand how credit documentation, monitoring, verification, and co-benefits are likely to be viewed by the market.
For Exchanges
Prepare quality signals for future listings.
Add an independent quality layer that helps marketplaces organise supply, improve buyer confidence, and distinguish stronger credits.
