The Climate Bonds Initiative has convened a Marine Technical Working Group to develop new assessment criteria for low-carbon investments in the marine sector. The Marine Technical Working Group brings together international marine scientists, industry specialists and academics with widespread expertise in marine science, including sustainable fisheries, aquaculture, marine energy and resources, coastal zones, ecosystems and infrastructure. After development, public consultation and review the finalised Marine Sector Criteria will go before the independent Climate Standards Board for approval. On release, the Marine Criteria will then be available as a sector specific screening tool for investors to assess the green credentials of bonds financing marine investments and for bond issuers to gain certification of low-carbon marine-related investments under the Climate Bonds Standard.
