DFDS has launched a climate action plan which will require third-party haulier trucks to cut their fleets emissions.
The move is part of the ferry operator's plans to cut its carbon emissions by up to 35% over the next 10 years as part of wider plans to become carbon neutral by 2050.
Other goals include cutting emissions from its own fleet of trucks and its port equipment and, wherever possible, the introduction of electric trucks.
DFDS’ ferry and logistics network covers countries bordering the Baltic Sea, North Sea, English Channel and the Mediterranean.
In 2019, the network emitted around two million tons of CO2 of which 90% was from ferries and the rest mainly from logistics operations.
Torben Carlsen, chief executive of DFDS, said: “I am very happy that we now have an ambitious and comprehensive climate action plan in place.
“It clearly states how we can and will take responsibility for the environment. The plan will also help us stay relevant as a provider of ferry and logistics services for both freight customers and passengers in the coming decades.”
