In 2010, HELCOM completed the initial assessment of the ecosystem health of the Baltic Sea – including the associated costs and benefits to the society (link to report).
An update on the overall state of ecosystem health in the Baltic Sea was made in the project Second Holistic Assessment of Ecosystem Health in the Baltic Sea (HOLAS II). Published in 2017, the State of the Baltic Sea report features improved tools and approaches. The first version of the report is available on a dedicated website and as a PDF, and the updated and finalized report (PDF, 31 MB) was published in mid-2018.
