The aim of environmental monitoring is to verify that there is no significant impact on the Baltic Sea due to project implementation. It also verifies that impact is in line with the environmental impact assessment (EIA) reports and fulfills certain permit conditions.
Nord Stream 2 environmental monitoring is based on the five national environmental monitoring programmes. Extensive surveys conducted during the EIA phase informed each of these programmes, which were approved by the national environmental authorities.
The programmes include monitoring of 25 parameters to collect information about abiotic, biotic and socio-economic parameters across all five countries. This takes place before, during, and after construction.
Among the parameters are water quality, seabed sediments, underwater noise, bird populations, marine mammals, fish and fisheries, cultural heritage, munitions, maritime traffic and onshore environment. Special focus is paid to protected areas like Natura 2000 sites.
Independent contractors monitor and verify the actual environmental impacts of construction activities and the operation phase. The results are submitted to the national environmental authorities and published in overall annual summary reports and press releases on our website.
