The 6 Top Carbon Market Registries(2022)

A carbon market registry is an electronic or physical record of transactions within a carbon market. It includes basic information on the participants in each transaction, as well as the quantity, price, and date of the transaction.

Mechanisms to ensure compliance with emissions reductions commitments made under the Kyoto Protocol include:

International Transaction Log (ITL): The ITL is a global, decentralized transaction registry that allows for the tracking of all Kyoto Protocol units and emissions reductions.

Joint Implementation (JI) Supervisory Committee: The JI Supervisory Committee is responsible for overseeing the activities of Joint Implementation projects and ensuring their compliance with the Kyoto Protocol.

Clean Development Mechanism (CDM) Executive Board: The CDM Executive Board is responsible for overseeing the activities of CDM projects and ensuring their compliance with the Kyoto Protocol.

Compliance Committee: The Compliance Committee is responsible for considering cases of non-compliance with the Kyoto Protocol and making recommendations to the Conference of the Parties on how to address them.

The Compliance mechanism of the Kyoto Protocol is designed to ensure that Parties meet their commitments under the Protocol.

The mechanism includes a number of different procedures and processes, as well as a range of different bodies and institutions, all of which work together to promote and ensure compliance with the Kyoto Protocol.

Below are some of the top carbon market registries at the moment, as the sector continues to grow there will be more added to this list.

The Markit Registry also lists all Plan Vivo projects and project documentation that is responsible for the issuance of PVCs (PDDs, technical specifications, annual reports and audit reports).

This information is important for anyone interested in buying or selling PVCs, as it allows them to verify that the certificates they are purchasing are actually associated with a registered project.
