International shipping can reach zero or very near zero tank-to-wake (TTW) CO2 emissions by 2050, and achieve 95%+ reductions in well-to-wake (WTW) greenhouse gas (GHG) emissions from 2018 levels, in scenarios aligned to a 1.5°C global temper ature goal , according to a report from ERM, UMAS and UCL, commissioned by the UK Department for Transport as part of the evidence base for maritime decarbonization policies.

As disclosed, the study used UMAS’ Global Maritime Transport Model to assess the relative costs and potential impacts of technology transitions within international shipping under three core scenarios.
