At the end of the year 2010 European Commission adopted the EU Strategy for the Danube Region (EUSDR) that aims to deepen the cooperation of 14 countries in the Danube region. These are Austria, Bulgaria, Croatia, Czech Republic, Germany, Hungary, Romania, Slovakia, Slovenia, Bosnia and Herzegovina, Montenegro, Serbia, Moldova and Ukraine. Countries are very diverse – EU members, candidate countries, potential candidates as well as countries from the European Neighbourhood Policy. Despite the different statuses, the listed countries share common geographical area, history and part of the cultural heritage and therefore connection seems especially reasonable in the field of environment protection, ensuring prosperity and strengthening of the Danube region.
