This Opportunity Green study, commissioned by Transport & Environment, draws on analysis of international law to explore the legal implications of action by one state or multiple states outside the IMO on GHGs from the maritime sector. It finds that provided a few important legal and enforcement considerations are respected and built into the design of any policy measure, there are no legal obstacles to national or regional action, indeed, countries are obligated to take such action.
