The Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (MMCZCS), RMI, Danish Shipping, and Maersk Oil Trading have released two publications outlining their new Maritime Book & Claim system, which will undergo a pilot later this year. Under the system, ships will be able to ‘book’ emissions associated with individual voyages, which consumers can then ‘claim’. The system seeks to accelerate decarbonisation by empowering green shipping services to find customers offering green premiums, regardless of geographical constraints.
