Good environmental status (GES) in relation to eutrophication is achieved when "the good environmental status is achieved in accordance with the Water Framework Directive (WFD) and when the eutrophication status is at least good in accordance with the integrated HELCOM eutrophication assessment". For the assessment of good environmental status of coastal waters < 1 nautical mile related to D5, the following criteria are used in Commission Decision (EU) 2017/848: D5C1, D5C2, D5C4, D5C5, D5C6, D5C7, D5C8. For the assessment of good environmental status of the open Baltic Sea > 1 nm, the following criteria will be taken into account in Commission Decision (EU) 2017/848: D5C1, D5C2, D5C4 and D5C5. Criterion D5C3 has been taken into account in some coastal waters as part of the assessment of the biological quality element phytoplankton (biovolume of cyanobacteria). Secondary criterion D5C8 is under development. Explanation: Germany does not update the general description of good environmental status (GES) from 2012 at descriptor level in this reporting exercise. During the reporting period, Germany has worked with the countries bordering the Baltic Sea in the framework of the EU's CIS process and HELCOM to develop methodological standards (indicators, evaluation procedures). Specific aspects of criteria and indicators that contribute to a quantitative assessment of good environmental status are reported in the reporting scheme Art. 8_GES. For the assessment of the criteria set out in Commission Decision (EU) 2017/848, the relevant assessments under other EU directives shall be taken into account under Article 8_GES, and, as far as possible, the regional assessments that have been coordinated so far and will be, on a case-by-case basis, supplemented by national assessments.
