Norwegian seafood companies Grieg, Leroy, SalMar and Mowi are currently trialing various routes and methods to take their fish off the road and transport it instead by sea in order to cut emissions.

Today, Norwegian cargo transport is dominated by road transportation to Europe and air transportation to Asia and North America, both of which are heavily reliant on fossil fuels.

About 65,000-70,000 trucks bring salmon from Norway to Europe every year, while hardly anything is transported by ship.

For seafood companies, changing modes of transport can be an immediate way of cutting a large percentage of emissions, unlike with feed, which is far more complex and time consuming to modify, according to DNV Vice President and Director of its Green Shipping Program (GSP) Narve Mjos.
