The [Open Carbon Protocol (OCP)](https://www.ocp.earth/) is a carbon and climate asset registry, providing the platform for:
* **Collaborative, fast and antifragile** [**methodology development**](/ocp-handbook/methodologies/methodology-development-process.md)
* Project Developers, NGOs and other methodology curators work with a global panel of 8-15 experts to get methodologies improved and approved in 6-7 months (average)
* **Digital, efficient and cooperative** [**project proposal**](/ocp-handbook/projects/project-proposal-process.md)**,** [**validation & verification**](/ocp-handbook/projects/third-party-validation-and-verification.md)**, and** [**credit issuance**](/ocp-handbook/registry/credit-issuance-transfer-retirement.md)
* Project Developers upload pre- and post-issuance information and data and can share directly with VVBs, brokers/buyers, ratings agencies and insurance providers.
