Extraction from the report

The agreement on the provisional nutrient load reduction targets was signed in Krakow in 2007. These were calculated with the very first version of the Baltic Nest Institute’s (BNI) decision support system. Since then, tremendous work has been invested in improving both the tools and data sets – as well as the scientific justification for these – in order to provide the best possible advice on targets per each country to the HELCOM Ministers in October 2013.

Moreover, the process builds on the work by the HELCOM TARGREV project for strengthening the scientific basis of HELCOM’s eutrophication targets. The new maximum allowable inputs are calculated using the latest model developments at the BNI, and the nutrient load reductions are allocated to the Baltic Sea countries with a transparent and efficient tool from the BNI that uses the latest data from the HELCOM Pollution Load Compilation. Atmospheric nitrogen loads will be included in the allocation, so that countries can utilise measures on nitrogen emissions to reach their reduction targets, in addition to making reductions in loads to the Baltic Sea and rivers in the catchment.

Bo Gustafsson, one of the coordinators of the review process and the Managing Director of BNI in Sweden, says: “Primarily, what is new in the revised approach is that each piece of the puzzle is redone with greatly improved methods and data”.
