Abstract

Maritime transportation is considered the most efficient transport mode in economic and environmental terms. However, its impact on air pollution and global warming cannot be ignored. Especially ports located close to cities threaten public health with emissions from ships. The significance of the issue is understood better day by day by the authorities. The IMO has adopted mandatory measures to reduce emissions from international maritime transportation for ships. Despite efforts by the IMO to reduce ship-borne emissions, studies about the effects of air pollution caused by ships in port areas are insufficient. This study evaluated the effect of using shore power instead of an auxiliary engine on emission reduction. We examined 529 ships that visited the container port in Izmit Bay. We used two bottom-up methods, EPA and Entec, for emission estimation of the ships. For cold ironing, we used the emission factors of the Turkish national grid. As a result of this study, when cold ironing was applied instead of the auxiliary engine, the emission reduction rates of CO 2 , NOx, PM, and SO2 were 21.02%, 91.64%, 58.67% and 2.42% respectively. The results obtained from the analysis showed that the application of cold ironing has environmental advantages for port areas.
