Sustainability
For Sund & Bælt social responsibility means contributing to social, environmental and economic sustainability.
Benefits for nature and the climate from the Fehmarnbelt tunnel
Green shortcut to the future
The Fehmarnbelt tunnel means that international trains and lorries passing through Denmark will be saved a 160 km detour, thus significantly reducing their CO2 emissions.
A greener corridor
The Fehmarnbelt link will be a major contributor to Europe's future sustainable transport network by making it attractive to switch freight transport from road to rail.
We're building alongside nature
The construction of the Fehmarnbelt tunnel will result in an extensive new natural landscape, which will increase biodiversity - on land and in the Fehmarnbelt.
The Fehmarnbelt tunnel will be built sustainably
The Fehmarnbelt tunnel has the potential to become a 'climate beacon' for infrastructure projects where the project contributes to the green transition from the outset. Read more about the climate strategy here.
We want to contribute to social, environmental and economic sustainability
Decent pay and working conditions
Sund & Bælt requires contractors to ensure orderly conditions during the construction of the Fehmarnbelt tunnel. This includes pay and employment conditions and requirements relating to the working environment, safety and accommodation.
A safe workplace
As the Client, Sund & Bælt bears the main responsibility for health and safety on the Fehmarnbelt project and for ensuring that working environmental legislation is followed. We therefore attach significant importance to safety in our contracts with the contractors.

Visit Ægir - our environmental portal
The Fehmarnbelt project's environment portal is named after the giant sea god, Ægir, from Norse mythology. The portal offers the opportunity to view key environmental data, which is regularly updated by means of live data from our environmental monitoring buoys in the Fehmarnbelt.
Apprentice to the Fehmarn project
The Fehmarnbelt project wishes to contribute to the employment of trade apprentices, trainees and trainee clerical assistants. The major construction contracts stipulate a total of 500 full-time apprenticeships.
Green shortcut to Europe
The construction of the Fehmarnbelt Tunnel is co-financed by the European Commission, which has named the construction a priority project. The connection plays a key role in the transport network of the future in Europe.
