CEOs of major global shipping lines have issued a joint declaration at COP28, urging the International Maritime Organization (IMO) to establish regulatory conditions for the transition to green fuels. The unprecedented action calls for an end date for new fossil fuel-only vessel builds, a GHG pricing mechanism, vessel pooling for regulatory compliance, and a Well-to-Wake GHG basis. The CEOs emphasize the industry's commitment to IMO's GHG reduction targets and stress the need for regulatory support to accelerate the transition to zero-emission fuels. Notable participants include CMA CGM, Maersk, Hapag-Lloyd, MSC, and Wallenius Wilhelmsen.
