The objective of these guidelines is to help reduce the discharge of ship-generated marine litter (garbage) into the sea by the provision and improvement of the capacity and efficiency of port reception facilities and waste management practices onboard, thereby enhancing the protection of the marine and coastal environment. These guidelines were developed as part of the NOWPAP Marine Litter Activity (MALITA) project which has been initiated since its approval at the Tenth NOWPAP Intergovernmental Meeting (Toyama, Japan, November 2005).
