HELCOM holistic assessments (HOLAS) give a comprehensive overview of the ecosystem health of an entire regional sea – the Baltic Sea. These major assessments assist the region’s environmental managers and decision-makers, so that they can base their work on sound, up-to-date knowledge of the status of the sea.
In 2010, HELCOM completed the initial assessment (HOLAS I) of the ecosystem health of the Baltic Sea – including the associated costs and benefits to the society. The assessment was based on data from 2003 to 2007.
The second HELCOM ‘State of the Baltic Sea’ holistic assessment (HOLAS II) provides a comprehensive overview of the ecosystem health of the Baltic Sea based on data collected between 2011 and 2016.
HELCOM is currently carrying out the third holistic assessment (HOLAS III) of the Baltic Sea, covering the period 2016-2021. The results are expected to be published in 2023.
