The International Carbon Registry (ICR) is an international voluntary greenhouse gas (GHG) program, offering registration of climate projects and issuance of high-quality carbon credits generated by such projects. ICR enables the transfer of carbon credits between entities and/or their retirement for the purposes of offsetting emissions in line with entities’ respective decarbonization/net-zero strategies and limiting the risk of double counting credits.

Our Mission

Our mission is to provide a robust set of requirements based on internationally approved principles from early climate action initiatives. We will do this by creating a platform that provides access to finance for climate projects while promoting responsible and transparent offsetting practices and thus preventing double accounting. With our mission, ICR will support the emergence of a credible and transparent voluntary carbon market (VCM) which is critical to achieve the goals of the Paris Agreement and the UN Sustainable Goals.

Our Values

Trustworthywe strive to be consistent and transparent in our work and in all aspects honor the trust placed in us by those who choose the ICR for registration of their climate projects and for financing climate actions. 

Effectivewe are committed to making all our processes as effective as possible in order to allow our partners to focus on bringing their projects to life while safeguarding the reliability of registered projects and their methodologies with the issuance of high-quality carbon credits.

Innovativeour aim is to serve our customers in the best possible way by exploring and constantly adapting to new technology and regulations.
