The Global Centre for Maritime Decarbonisation (GCMD) is an independent, non-profit organization based in Singapore that works to accelerate the reduction of greenhouse-gas emissions from international shipping. Established in 2021 with industry and public-sector support, it focuses on enabling practical, scalable pathways to meet sectoral climate targets.
GCMD develops and executes pilots and trials, advances safety and operational guidelines, and supports the development of standards for low- and zero-carbon marine fuels such as ammonia, methanol, and sustainable biofuels. Its work also spans onboard carbon capture, lifecycle greenhouse-gas accounting, and measurement, reporting and verification frameworks. Acting as a neutral convener, GCMD brings together shipowners, ports, fuel producers, classification societies, regulators, and research institutions to de-risk first-of-a-kind deployments and inform policy and industry practice through evidence-based studies and toolkits.
