Decarbonising smaller vessels call for evidence

News article

Evidence sought on emission reduction measures for vessels with a gross tonnage of less than 400.

The Department for 91香蕉黄色视频 (DfT) is seeking evidence to inform policy making on its commitment to introduce emission reduction measures for vessels with a gross tonnage below 400 and vessels that could decarbonise quickly.

The new maritime decarbonisation strategy sets out the government鈥檚 aim for United Kingdom domestic maritime to achieve net zero fuel lifecycle greenhouse gas (GHG) emissions by 2050. This will also deliver wider environmental benefits including for air quality, which will 91香蕉黄色视频 the government missions to become a clean energy superpower, kickstart the economy and ensure people live well for longer.

The call for evidence is intended to gather further evidence to inform policy making relating to this commitment and to ensure that government interventions are effective, proportionate, well timed and meet emission reduction goals.

DfT wishes to gather evidence on:

  • the current and expected future capital and operational costs of zero, or near-zero, emission vessels
  • the current technology available and expected future technology developments to enable the transition away from traditional fuels such as diesel heavy fuel oil, marine diesel oil and marine gas oil
  • the type and quantity of GHG emissions and air pollutants emitted by traditionally fuelled and zero, or near-zero, emission vessels
  • the shipbuilding capacity and capability of UK shipyards to build and retrofit zero, or near-zero, emission propulsion vessels
  • the infrastructure, such as refuelling, shore power and charging capabilities at ports/marinas/harbours, currently in place and the future infrastructure needed to enable this transition
  • current access to finance to buy and build zero, or near-zero, emission vessels
  • issues of compliance and implementation, for example, there is no vessel registration system for many subsectors
  • the different methods of data collection and whether systems are already in place to measure emissions
  • any opportunities or barriers to this transition

.

The call for evidence closes on Friday 25 July 2025.
