Voluntary Carbon Credit Marketplace: How We Ensure Quality
Voluntary Carbon Credit Marketplace: Registry Verification
Specifically, every credit on GreenTonne is linked to a verified registry serial number from Verra VCS or Gold Standard. As a result, we never list unverified or self-issued credits on our platform.
Quality Rating System
Furthermore, our proprietary quality scoring rates projects across seven categories: registry standing, verification, additionality, permanence, co-benefits, transparency, and developer track record. Therefore, you can compare credits with confidence.

How GreenTonne Separates Marketplace and Registry Roles
Marketplace role
GreenTonne supports discovery, price comparison, transaction processing and buyer-facing evidence.
Program and registry role
Crediting programs set requirements and registries record serialized units, transfers and retirements.
Independent verification
Approved validation and verification bodies assess project design and monitored mitigation results; GreenTonne does not replace that work.
Our Marketplace Control Principles
Accurate inventory
Listings should be reconciled against seller authority, available volume, transfers and retirements.
Transparent price
The buyer sees the unit price, marketplace fee and final payable amount before purchase.
Qualified claims
We distinguish registry issuance, marketplace review and project-level quality instead of treating them as interchangeable.
