Endorsed Standards


*Further clarity is expected following the approval of Article 6 of the Paris Agreement at COP26



*Assessed by ICROA on the basis of the Review Criteria. Both Endorsed Standards and Conditionally Endorsed Standards are required to proactively inform ICROA of any updates or changes on an annual basis before Q3 of each year, along with the supporting documentation for an official technical review. Failure to do so may result in exclusion from the Code. For more information, please contact the ICROA Secretariat.

​**Conditional Endorsement is attributed to Standards that meet ICROA criteria for endorsement, and are pending the achievement of set threshold values in order to validate the full operationalisation of the Programme (e.g. registered projects, issued credits, etc). ICROA Accredited Organisations can use carbon credits from conditionally endorsed standards and will be Code compliant. For more details, please contact the ICROA Secretariat.
