Product Summary

The Markit Registry is the only registry that allows account holders to manage all their global carbon, water and biodiversity credits in a centralised, financial markets-based registry system. It provides end-to-end management of environmental portfolios and full support for existing and emerging environmental programmes and markets.

The Markit Registry supports both project developers looking to list credits and potential buyers sourcing projects. It enables users to manage environmental projects, credit issuances, transfers and retirements. We also provide publicly viewable documentation and holdings, and all project and listing documentations are reviewed to ensure compliance with relevant environmental market standards.

  • Request For Information (RFI)

    Our RFI platform is an anonymous online platform for the OTC environmental markets, displaying credits available for sale with indicative quantities and prices. These credits are searchable and viewable by registered buyers, who can send expressions of interest. Additionally, buyers may also enter specific criteria of credits that they are wishing to purchase. Introduction through the platform enables the parties to discuss terms of a potential bilateral transaction.

  • Pending Issuance Unit (PIU)

    Markit provides the infrastructure to enable you to track your forward sales of anticipated environmental credits. Each PIU represents an anticipated environmental credit to be delivered based on a specified standard-compliant project validation report. These anticipated units can be listed, serialised, held and tracked on the Markit Registry.
