Femern A/S is aware that the construction and operation of an infrastructure project the size of the Fehmarnbelt fixed link will affect the environment. Adverse environmental impacts will be avoided or minimised as much as possible.
Over the past four years of planning, Femern A/S has been committed to minimising the project’s negative consequences for the environment, climate and nature. Therefore, the environmental investigations that have been carried out ahead of the construction are the most comprehensive and thorough so far undertaken in Denmark. With the knowledge and data accumulated to date, experts on behalf of Femern A/S are developing and planning low-impact production methods and optimal technical solutions. The aim is to safeguard the local community during the construction and operational phases.
The latest and most environmentally appropriate production methods will be used during the construction phase. Traditionally, immersed tunnels are produced in dry docks on land and require a lot of space and create a poor working environment. With the Fehmarnbelt project, the tunnel elements will be cast at a factory specially constructed for the purpose.
Femern A/S is imposing higher specific environmental and climate requirements on the contractors compared to similar major construction projects. The spill from the dredging work will be limited as much as possible by using large-scale machinery and through good planning. The sediment spread from the dredging work will constitute the biggest environmental impact in the Fehmarnbelt – which is why spill must be kept to a minimum.
During construction work, noise will be limited as much as possible and concentrated in daytime hours. When the coast-to-coast facility becomes operational, fewer local residents will be exposed to noise than is the case today. Contractors will be required to use the latest and least noisy machinery.
When the project is completed, the Fehmarnbelt will gain new plant and animal life from the stone reef above the immersed tunnel near the coast. The stone protecting the tunnel will be transformed into new and attractive areas for flora and fauna.
