The guidance unpacks the core COP29 decisions and highlights key implications for host countries, activity participants, investors & intermediaries, designated operational entities, and independent carbon crediting programmes. It focuses on three essential areas: Article 6 mitigation activity development, the birth of an ITMO – from authorisation to the specification of the first transfer, and interoperability of registry infrastructures. The guidance was prepared with the support of the Federal Ministry for the Environment, Climate Action, Nature Conservation and Nuclear Safety.
