Global accounting of the environmental impact from maritime transport is an ongoing conversation. This study introduces the idea that emissions from open-sea cruising can accounted as stock at the port of arrival. An example is presented for the case of Mytilene (for a single month) where the in-port and open sea emissions are calculated and presented. In this specific analysis, during a single calendar month, 518 individual routes were identified with 42.47% being passenger ships and 33.98% being Ro-Ro/ passenger ships. The routes with the higher impact have been identified to be the ones with the highest combination of Deadweight Tonnage and frequency of arrival. Characteristically 117 of the total routes can be attributed to vessels with Deadweight Tonnage over 3000 tons. In the later part of the work, the study discusses two important aspects that should be under consideration in the overall maritime transport analysis. Firstly, the in-port emissions with a focus on sulphur oxides and secondly the integrated accounting of shipping emissions.
