We are pleased to announce that the Clean Underground Initiative has received another major international award. The European Commission for Cave Protection at the European Speleological Federation (FSE) recognized the quality of our work and awarded our initiative the second prize and the “Euro Speleo Protection” label. The first prize was awarded to the project of the Italian Speleological Association Pugliamo il buio, that also tackles the problem of karst contamination. The Awards were a part of the 12th Euro Speleo Forum Congress held in the Austrian city of Ebensee on August 25, 2018. As a symbolic prize, we received 200 meters of high quality speleological rope that will serve us well in future waste cleaning activities. This is another great acknowledgment for our Initiative and a good opportunity for domestic and international promotion of Croatian speleology.
