Environmental Monitoring

A number of measures will be taken to minimise the impact of preparatory and construction activities on the sensitive Baltic Sea environment, which has dense shipping traffic and historic sea mines.

Nord Stream 2 is committed to building the pipeline system in the most environmentally friendly and sustainable way. The pipeline route, construction plan and environmental monitoring programmes have been developed in close consultation with the competent environmental authorities in each country. Our team also benefits from the wealth of experience gathered during the construction and extensive monitoring of the existing Nord Stream Pipeline. The results from the multi-year monitoring of the previous project have showed that the impacts were minor, short-term and local.

Nord Stream 2 has selected independent contractors for environmental monitoring to verify the actual impacts of construction to the environment and marine life. The environmental monitoring programme includes 17 receptors that collect information about abiotic, biotic and socio-economic parameters across the five countries whose waters the pipeline passes through. Monitoring will take place before construction, during specific construction activities and after the pipeline is completed. National monitoring programmes have been approved by competent authorities who will verify the compliance with permit provisions. 

The monitoring programme includes 9 main categories: water quality, underwater noise, bird populations, marine mammals, flora and fauna, fish and fisheries, cultural heritage, munitions, and onshore environment. In each area, monitoring activities ensure that construction impacts remain within the limits laid out in approved permitting documents, in addition to informing the implementation of mitigation techniques.
