First version of the State of the Baltic sea report – June 2017 – to be updated in 2018
Key findings

Sample Heading


Nutrient inputs from land have decreased clearly, but effects are not yet reflected in the status of all sub-basins.

Sample Heading


The contamination status is elevated in all of the Baltic Sea, but some improving trends are seen.

Sample Heading


Biodiversity status is inadequate for most assessed species, and continued efforts to support biodiversity are of key importance.


Human activities contribute to society; to our well-being and economies, but they are also the main sources of pressures on the Baltic Sea environment.

Human activities and the ecosystem >

Pressures both from land and sea act on the Baltic Sea environment.

Assessment results on pressures >

Marine mammals, birds, fish and habitats show unfavourable status in most of the Baltic Sea.

Assessment results on biodiversity >

The Baltic Sea Impact Index estimates the cumulative burden on the environment of all pressures from human activities, and displays it on a spatial map.

Assessment of cumulative impacts >

Measures to improve the Baltic Sea environment are undertaken by actors at many levels; regional, national, county and local levels, as well as by initiatives in the private sector.

HELCOM actions for improvement >
