Policy approval for CORSIA under Isometric

The process for submitting insurance policies for approval

 

In July 2026, Howden was appointed by Isometric, the certification standard for climate and sustainable development, to approve insurance policies that support the eligibility of carbon credits for CORSIA – the global decarbonisation scheme for international aviation.

 

Insurers wishing to submit a policy for review should follow the instructions below:

  1. Review Isometric's CORSIA Criteria for approved insurance or related instruments ('the Criteria') and Deed of Undertaking
  2. Ensure that the policy wording and supporting documents meet the Criteria
  3. Email [email protected] with your intention to submit
  4. Agree to Howden's T&Cs and engage them for the service
  5. Complete submission form and send policy wording, templates and supporting documents to Howden
  6. Howden to review the information and evaluate compliance with the Criteria
  7. If the criteria are not met, Howden to provide feedback to the insurer
  8. If the criteria are met, Isometric  to add approved provider to their Guidelines for CORSIA-eligible units
  9. Approved policies to undergo re-assessment annually and following any material change to the Criteria.

* Insurers wishing to challenge the outcome of the evaluation, should follow this process.

Information for project developers and investors

Project developers seek insurance for carbon credits issued in line with CORSIA because it offers a layer of financial and regulatory assurance that enhances the credibility and marketability of their projects.

Political risk insurance, combined with a host country authorisation, is one route for project developers to seek eligibility of carbon credits for CORSIA. It provides protection against the risk of double counting, a strict eligibility requirement for carbon credits.

Products used to support CORSIA eligibility will protect against the risk that a host country government may renege on or reverse a commitment not to claim carbon credits toward their own national target under the Paris Agreement. In such cases, insurers will provide either alternative carbon credits or monetary compensation to support the project developer to replace double-counted credits.  Insurers may also offer policies that mitigate other risks, for instance related to credit invalidation, reversal, or non-delivery.
