EEA Core Set of Indicators (CSI)

The EEA management board approved the core set of indicators in March 2004. The set has been established for three main purposes: to provide a manageable and stable basis for indicator-based reporting by the EEA; to prioritise improvements in the quality and geographical coverage of data flows, especially Eionet priority data flows; and, to streamline EEA/Eionet's contributions to other European and global indicator initiatives, for example, EU structural indicators, EU sustainable development indicators and OECD environment indicators.

Is eutrophication in European surface waters decreasing?
The highest summer chlorophyll-a concentrations were observed in coastal areas and estuaries and are at many locations associated with nutrient inputs from major rivers. Of the 413 stations reported to the EEA in 2005 with more than 5 years of observations, decreasing trends in summer chlorophyll-a concentrations were found at 7% of stations, increasing trends were found at 8% of stations, and the majority of stations (85%) indicate no statistically significant change in concentration. The stations with descreasing trends are located either in the Baltic Sea or along the coast of Italy.
