Pathways towards 50% reduction of GHGs from shipping until 2050

The UN agency for international shipping IMO has agreed to reduce greenhouse gas (GHG) emissions from
shipping by at least 50% by 2050. There are yet no comprehensive studies showing how the target can be
reached, but there are studies assessing the role of energy efficiency measures, alternative marine fuels as well
as different policy instruments. The overall aim of this project is to assess the technical solutions and policy
instruments with large potential to contribute to IMO’s GHG target and show possible pathways both in Sweden
and internationally. Specifically, the project will (i) assess 4-5 technical solutions and 2-3 policy instruments with
large potential to reduce GHGs, (ii) assess scenarios for cost-effective choices which also considers the carbon
budget, (iii) contribute with a roadmap for how shipping can reach the IMO GHG target, developed in dialogue with
shipping stakeholders and relevant authorities, and (iv) present and spread the result also internationally.
