The aim is to have 'seas without adverse effects from eutrophication'. The objective is implemented by means of the operational objectives UZO1.1, UZO1.2 and UZO1.3. The environmental objectives established in 2012 and their description under the 2012 MSFD report continue to apply. They are the basis for the 2016-2021 programme of measures, notified to the European Commission in 2016. Since the implementation of the measures was only started in 2016, an assessment of the progress and effectiveness of the measures as a basis for updating the environmental objectives is often not yet possible. Where possible, the text of the text shows the achievement of objectives and/or the state of implementation of the measures. The indicator evaluation on progress towards achieving targets is reported in the Progress Report on operational objectives. In the Baltic Sea Action Plan, HELCOM has established a maximum permissible nutrient input of 21.000 tonnes of phosphorus and 600.000 tonnes of nitrogen for the whole Baltic Sea. As a result, concrete nutrient reduction targets have been set based on the MARE-NEST model for the countries bordering the Baltic Sea (HELCOM, 2007). Germany has committed to reduce its nutrient inputs into the Baltic Sea by 240 tonnes for phosphorus by 2016 and for nitrogen by 5.620 tonnes. Reduction targets are based on the parameter visibility depth. The nutrient reduction targets have been reviewed scientifically and new targets have been set in HELCOM's Ministerial meeting in 2013. At the 2013 HELCOM Ministerial meeting, Germany committed itself to reducing the annual nitrogen inputs into the Baltic Sea by around 7.670 tonnes (water and air-borne inputs combined) and a reduction of phosphorus inputs by around 170 tonnes compared to the base period 1997-2003.

Operational environmental objective for the overarching environmental objective 'seas without adverse effects from anthropogenic eutrophication': Nutrient inputs via the rivers are to be further reduced. Reduction targets have been set in the programs of measures of the WFD. The phosphorus and nitrogen compound loads from German tributaries to the Baltic Sea have been declining since the 1980s. However, since 2000, there has hardly been a decreasing trend and, very strong annual fluctuations have occurred. In 2014, about 2,800 tons of nitrogen and about 112 tons of phosphorus were introduced into the Baltic Sea via the river basin districts Schlei / Trave and Warnow / Peene (UBA 2017). If one additionally considers the entries of smaller inflows, e.g. into the small lagoon in the Oder catchment area, as well as the German entries into the Oder, then approx. 9,600 tons of nitrogen and approx. 360 tons of phosphorus were registered in the Baltic Sea in 2014 (UBA 2017). The nutrient inputs of the surface waters draining into the Baltic Sea with the substance input model MoRe decreased by 19% (5,119 tons) for nitrogen and 17% (168 tons) for phosphorus compared to the evaluation periods 2012-2014 and 2006-2011 (UBA 2017, Fuchs et al 2016). Compared to the 2012-2014 and 1983-1987 evaluation periods, nutrient inputs decreased by 65% ​​(40,835 tonnes) for nitrogen and 78% (2,844 tonnes) for phosphorus (Source: MoRe). According to the MoRe substance input model, agriculture (78% of nitrogen inputs and 51% of phosphorus inputs) followed by point sources (eg sewage treatment plants) (9% of nitrogen inputs and 20% of phosphorus inputs) were the main contributors to nutrient inputs over the period 2012-2014. Entries from urban areas and atmospheric deposition on surface waters in the catchment area of ​​the Baltic Sea played a subordinate role.

Operational environmental objective for the overarching environmental objective 'seas without adverse effects from anthropogenic eutrophication': Nutrient inputs via remote entries from other marine areas should be reduced. This should be done in the framework of the regional cooperation of HELCOM.
