Eutrophication is the most serious environmental problem faced by the Baltic Sea. Signs of eutrophication include the blooms of blue-green algae encountered every summer. Eutrophication is caused by too great loads of phosphorus and nitrogen entering the sea. To be able to stop eutrophication and save the Baltic Sea, we need immediate and significant reductions in the nutrient loads.
The Foundation’s Clean Baltic Sea projects work to stop the eutrophication of the Baltic Sea by reducing the nutrient loads that end up in the Baltic Sea as efficiently as possible. The Foundation’s goal is to significantly and concretely promote the target set by Baltic Marine Environment Protection Commission (HELCOM), i.e. for the Baltic Sea to reach a good ecological status by the year 2021. In 2005–2015, the Foundation has completed 14 projects that protect the Baltic Sea. The projects have reduced the annual phosphorus load of the Baltic Sea by more than 2,000 tonnes. The first Clean Baltic Sea project was initiated in 2005 in St. Petersburg, and its objective of an annual reduction of over 1,000 tonnes of phosphorus was reached in 2011. All in all, the phosphorus load entering the Baltic Sea from St. Petersburg has diminished by 1,700 tonnes (70%) from 2004, equalling a reduction of almost 30% in the phosphorus load of the Gulf of Finland (HELCOM). In terms of environmental impact, the Foundation’s St. Petersburg project is one of the most significant water protection projects ever carried out in the Baltic Sea.
