UK Maritime Decarbonisation Strategy Targets Zero Emissions by 2050 for Smaller Vessels

The UK Department for Transport (DfT) has introduced a Maritime Decarbonisation Strategy with a strong emphasis on reducing greenhouse gas emissions in domestic maritime transport. The goal is for this sector to achieve zero fuel lifecycle GHG emissions by 2050, with interim targets of at least 30% reduction by 2030 and 80% reduction by 2040 compared to 2008 levels. The strategy specifically targets vessels below 400 gross tonnage in subsectors that have the potential to quickly reduce their carbon footprint through clear pathways to decarbonisation.

A call for evidence (CfE) has been issued by the Government to gather information that will inform policy-making related to the decarbonisation of smaller maritime vessels. The focus of this strategy includes leisure boats, inland waterways, and sea-going vessels within the UK Exclusive Economic Zone (EEZ). Smaller vessels below 400GT that are capable of decarbonising quickly due to short duty cycles, regular access to recharging or refuelling, and onboard space for storage of batteries or hydrogen are specifically targeted.

The Maritime Decarbonisation Strategy acknowledges the importance of addressing emissions from smaller vessels below 400GT, which are projected to contribute significantly to domestic maritime emissions as larger vessels decarbonise. While the official government policy targeting emissions reduction in smaller vessels is expected in late October 2025, businesses in the maritime industry subsectors should start working on their decarbonisation roadmaps and exploring suitable propulsion system technologies. Ricardo, a global engineering company, offers support in selecting the right technologies to reduce environmental impacts and navigate regulatory complexities in the maritime sector.
