02.0 / WHAT HAPPENED

Beyond the world-firsts, CarbonMarketsHQ maintains 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. All of it is open, so a standard, a developer or an auditor can read the rules as they will actually run.
