I-TRACK Carbon Dioxide Removal

An I‑TRACK for Carbon Dioxide Removal certificate is referred to as an I-TRACK(CDR) or C-Capsule and is a standard for durable Carbon Dioxide Removal (CDR). As an EAC, I-TRACK(CDR) conveys information about the production of a unit of carbon dioxide removed from the atmosphere such as where the capacity of the Production Facility, and the carbon dioxide removal source.

Unlike traditional emission avoidance or reduction offsets, I-TRACK(CDR) only certifies carbon that has been durably removed from the atmospheric cycle. Carbon Dioxide Removal is required on a large scale to reach the Paris Agreement targets and keep 1.5 alive. Achievement of Net Zero means that carbon markets need to evolve beyond the traditional offset approach; a transition recognized by many governments, NGOs, and market players. I-TRACK(CDR) helps meet the growing demand for certified CDR activities as governments and businesses work toward NetZero.

I‑TRACK(CDR) can be used for a variety of (voluntary) requirements including Scope 2 reporting, national energy reporting, and general End-user claims, and allows all electricity users to make a conscious and evidence-based choice for carbon dioxide removal, in any country where service providers have been given Pre-Accredited by the International Tracking Standard Foundation.

The I-TRACK(CDR) Product Code held by C-Capsule is an I-TRACK Foundation Accredited Product Code that describes the application of the International Attribute Tracking Standard. The I-TRACK(CDR) Code sets out the definitions, processes, and procedures that form the requirements for the issuance, transfer, and redemptions of an I‑TRACK(CDR).


The I-TRACK Foundation signed a memorandum of understanding (MOU) with Terrametric Solutions for the development of a Carbon Dioxide Removal (CDR) Attribute Tracking Certificate system called C-Capsule.


The I-TRACK(CDR) Code defines all procedures and processes relevant to the facilitation of the I-REC for electricity Product Certificates.


The I-TRACK(CDR) Product Code was approved by the I-TRACK Foundation Board and went to general consultation at the end of 2022.

The I‑TRACK for Carbon Dioxide Removal Governing Council (the I-TRACK(CDR) Council) is made up of a group of stakeholders (still currently being formed) whose goal is to support formalizing the governance and oversight of the I-TRACK(CDR) Product Code.


For the I-TRACK(CDR) Council, all Accredited parties (Code Manager, Registry Operator, Issuer, Labelling Authorities, and Platforms) will have a future role, as will Market Players, their clients, and third-party stakeholders.


To accommodate these groups, the I-TRACK(CDR) Council stakeholders will be appointed with voting rights. The I-TRACK(CDR) Council will take positions on the geographic availability of tracking instruments, Code changes, market barriers, adherence to national regulations, and coordination with standards, governments, and other stakeholder groups.


More information about the Council can be requested by the I-TRACK Foundation secretariat.


Terrametics Solutions/C-Capsule has been approved as the Code Manager for the I-TRACK for Carbon Dioxide Removal (or C-Capsule) product and is responsible for the detailed regulations of the I‑TRACK(CDR) service and coordination with partner Issuers around the world.


The I-TRACK for Carbon Dioxide Removal [I-TRACK(CDR)] Product Code, owned by Terrametrics, has Pre-Accredited by the International Tracking Standard Foundation.

The CDR Registry will be designed and developed by a team that specializes in energy attribute certificate registries.




Market Facilitators (I-TRACK Accredited Entities) and Market Players are dependent on each other for a thriving EAC market. Market Players need a robust EAC system that adheres to international best practices to enable them to make trustworthy energy claims. These instruments are provided by Market Facilitators, who are in return dependent on the use of these instruments to continue their facilitation of the market.


The International Tracking Standard Foundation requires all Market Facilitators to ensure a level playing field for all Market Players and guarantee – without exception – a fair and competitive market. This means that all Participants and Registrants must pay the same fees for the same services.


I-TRACK(CDR) Market Players

Production device owners or entities acting on their behalf must register as a ‘registrant’ with the Issuer that is responsible for the issuance of I-TRACK(CDR) in the relevant country. A Registrant is the only party that can register a production device with the local Issuer and requests the issuance of I-TRACK(CDR).


The Registrant must always request that I-TRACK(CDR) be issued into the account (trade account) of a Participant. The Registrant can also be a Participant, but this could also be a third party. Registration as a Registrant is free. However, there are fees attached to the registration of production devices.


For specific instructions and registration documents for a specific country, please see the documents on this page or visit a specific country page through the world map.


A Participant is a Market Player, trader, or consumer with an account on the Registry of the Code Manager. They may redeem certificates on their behalf, or behalf of their clients and can trade certificates from their primary account to the primary account of another market player.


Participants have three main account types:


  • Primary account
  • Sub-account(s)
  • Redemption account(s)


In general, Participants have one primary account and an unlimited number of subaccounts and redemption accounts. Registration as a Participant has associated fees.
