Previous studies based on life‐cycle assessment (LCA) in Denmark and Sweden have shown that the fishery is the environmental “hot spot” in the life cycle of certain fish products. Within the fishery, fuel consumption is one of the most important factors addressed by LCA. The present study reveals that there are great differences in fuel consumption between fisheries targeting groundfish or shellfish and those targeting pelagic fish or industrial fish. Here, I show that fuel consumption per kilogram of caught fish varies considerably as a function of fishing gear and vessel size, even considering the same target species. I argue that these differences need to be addressed in the search for a fuel‐efficient fishery. Improvements in fuel efficiency may be consistent with other objectives, such as reduced impacts on seafloor habitats and reduced discard.
