Building the pipeline in the most environmentally friendly and sustainable way is an absolute priority for Nord Stream 2, which has undertaken multiple measures to minimise the impact of construction on the sensitive Baltic Sea. This includes fulfilling national and international requirements for permits, along with comprehensive environmental monitoring throughout construction and operation. Learn how the process unfolded in the timeline below.

Cross-border infrastructure requires international cooperation in adherence to a variety of laws, conventions and treaties. Nord Stream 2 initiated the process in 2013 by submitting a Project Information Document (PID) to national and international authorities, non-governmental organisations and other stakeholders for public consultations in the planning phase. With the feedback received during this process the company then submitted five national Environmental Impact Assessments and published an “Espoo Report,” which documented potential transboundary impacts for consultation at the international level according to the Espoo Convention.

Throughout multiple phases of public consultation, Nord Stream 2 engaged with all interested stakeholders to develop a safe and sustainable pipeline. As a result of these efforts, all permits have been granted. The company is committed to complying with permit requirements, and with construction now nearly complete, monitoring programme results have already shown no significant impacts on the Baltic Sea environment thus far.
