Referring 3rd IMO GHG study maritime transport is responsible for about 2.5% of global greenhouse gas (GHG) emissions emitting around 940 million tons of CO2 annually. This emission figure is projected to increase significantly if serious mitigation measures are not put in place. Thanks to the studies conducted by IMO GHG emissions from international shipping to be reduced, actually the projection of the reduction amount is 50% achieved by 2050 compared to 2008. Today, navy vessels are not responsible for the IMO emission regulations as commercial vessels, but special regulations may appear in the future. Therefore energy analysis can be needed also for the naval vessels in the future. In this paper, the initial step for performing a ship energy system analysis, which is called “Reference Energy System”, has been developed for a generic frigate. The aim of this work is to provide to open a window for energy analysis of naval platforms.

As a result of the continuous pollution of the air, seas and soil, the deterioration of the natural equilibrium can be felt severely. Therefore, the prevailing vision of sustainable environment is frequently mentioned in the international arena. There are many industrial sources of pollution. Each of them significantly affects the environment. In the seas, the biggest source of pollution is the ships. Pollutants originating from ships are solid pollutants, bilge water, ballast water, anti-fouling system, etc. Another important source of pollution is wastewater. Untreated wastewater discharged to the sea will cause the natural balance to deteriorate. Therefore, wastewater treatment equipment is needed. The integration of equipment in ship design is a challenging process and many criteria must be considered together. In this study, it is stated that the criteria of the ship wastewater system will be evaluated and a set of alternatives is determined by Analytical Hierarchy Process (AHP). In addition, in accordance with a scenario created by considering the integration constraints of these systems into the ship, a hybrid model in which the 0-1 Goal Programming and AHP weights are applied, and the optimum solution (equipment) is selected which satisfies the determined constraints.

This study aims to provide brief information about the scope, purpose, main targets, main activities, expected outcomes and impact of the Erasmus Plus project entitled “This is the last call for Planet Lovers, Come and Save Your Planet: Project Proposal”. It deals with the topics of energy efficiency, carbon footprint, green buildings, green practices, climate change policies in the globe, and global resources. The project has been designed as a training course which will arouse the environmental awareness of youth workers and stimulate them to gain environmental literacy skills. It aims to enable the youth workers and young generation to gain environmentallyfriendly behaviors and competencies to find alternative ways how to struggle with climate change which has a huge impact on our globe. Within the project program, the youth workers will take part in international,cross-cultural learning environment where they will get knowledge about the policies and implementations done in Europe. Significance of being an environmentally literate person has been emphasized within the frame of this study and further recommendations have been suggested.
