The first ever attempt to assess the good environmental status (GES) for marine litter in Montenegro was introduced by Ms Milica Mandić of the Institute of Marine Biology in Kotor within the frame of the GEF Adriatic project. The assessment of GES was shared with the interested country representatives from the Ministry of Ecology, Spatial Planning and Urbanism, the Environmental Protection Agency of Montenegro, the Public Enterprise “Morsko Dobro”, the “Green Home” NGO, and the German Corporation for International Cooperation (GIZ) project. The participants were provided with detailed information on: important policies on marine litter in Montenegro; pressures and impacts related to marine litter; methodology of GES assessment for all marine litter indicators; scales of assessment; the current state regarding marine litter in Montenegro (in comparison to threshold values); and proposed management measures for tackling marine litter and needs for further development.
