WASHINGTON – Dec. 18, 2025 | Verra has published an initial list of three approved insurers to support project developers seeking to generate Verified Carbon Units (VCUs) for use under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). This helps expand the available options for eligible credits issued by Verra’s Verified Carbon Standard (VCS) Program to receive a CORSIA label and be used under the offsetting scheme set up by the International Civil Aviation Organization (ICAO).
The insurance products are offered by the following insurance carriers: CFC Underwriting Limited; Oka, The Carbon Insurance Company; and Artio Carbon Limited. Each of the carriers’ products have been independently assessed by global insurance intermediary Howden to ensure they meet Verra’s criteria.
Under CORSIA rules, eligible VCUs from 2021 onward can be used by aircraft operators only where the risk of double claiming has been addressed. Double claiming occurs when the same emission reduction is claimed both by a host country (i.e., where the project is located) toward its national climate targets and by an aircraft operator toward its CORSIA obligations. To prevent double claiming, the host country must submit a corresponding adjustment to its national carbon registry, which is linked to UNFCCC reporting. However, where this has not yet occurred, project developers must mitigate the double claiming risk by securing insurance coverage that compensates for any affected VCUs.
Project developers must also sign a CORSIA Accounting Deed of Representation, which Verra updated this week along with the relevant insurance criteria, after it invited feedback from project proponents on the original version published last month. While the current deed applies only to projects with a single project proponent, a new deed will be released in the coming days for projects with multiple proponents.
