Several London Boroughs use contractors to haul refuse barges up and down the Thames. What should these Boroughs be doing to ensure the tugs hauling the refuse barges are brought into line with diesel emissions similar to Euro 6 equipped HGVs?

Any comparison between freight hauled by barge or boat and freight hauled on road should take into account the fact that a single vessel is capable of hauling many times the amount hauled by a single HGV. Even a small barge can haul hundreds of tonnes compared to a typical HGV payload of less than 40 tonnes.

By removing HGVs from the roads freight and waste barges also help reduce congestion and move the engine emissions further away from where people live, reducing the impact.

That said it may be possible for some vessels to improve their emissions by replacing the engine, retro-fitting abatement equipment or other interventions.  TfL are currently beginning a trial of abatement equipment on some of the Thames Clippers.

Vessel operators can also do their part by ensuring that they sail their boats and ships as efficiently as possible and undertake proper maintenance of the engines to keep them as efficient as possible.

Boroughs could explore ways to work with their operators to further reduce emissions from the vessels they use. These might include helping or incentivising them to use newer vessels, working with them to reduce the number of trips needed or fitting emissions abatement equipment on older vessels.
