State of the Baltic Sea 2017

The second HELCOM State of the Baltic Sea assessment gives a comprehensive overview of the ecosystem health of the Baltic Sea. The first results were released in mid-2017, and the final report will be published by mid-2018.

The overall state of ecosystem health in the Baltic Sea is being assessed for the second time. The initial assessment was completed in 2010, resulting in the HOLAS I assessment report (PDF, 3.3MB). The first results were published in mid-2017 as a PDF and on a dedicated website at

This new, improved assessment

  • gives insight on key human activities in the Baltic Sea and on individual and cumulative pressures that impact the marine environment
  • assesses whether the environmental status of biodiversity, eutrophication, hazardous substances etc. in the Baltic Sea is good
  • introduces regional analyses of the costs of a deteriorating marine environment
  • considers measures taken so far for improving the status of the sea.

The State of the Baltic Sea report has been under preparation since 2014. Finalization of the assessment is a priority of the EU Chairmanship in HELCOM.
