A public library of methodologies, compiled to code
Issuance-grade, open reference implementations across Gold Standard, Verra and the CDM.
WRITE-UP IN PROGRESSThis account is still being expanded. The figures and the evidence links on this page are current and checkable.
Beyond the world-firsts, CarbonMarketsHQ maintains the only public, end-to-end reference implementations of several major methodologies on Hedera Guardian. The library spans clean cooking (MECD v1.2, the version behind the first fully digital issuance, through v2.0), mangrove restoration (VM0033), REDD (VM0048, in progress) and CDM methodologies (AMS-III.H, ACM0006, ACM0007), with durable-removal pathways now piloting with early partners. Each one is a piece of open public infrastructure, and the corpus that trains what we build next.
