Estimating shipping emissions in the region of the Sea of Marmara, Turkey

In this paper exhaust gas emissions from ships in the Sea of Marmara and the Turkish Straits are calculated by utilizing the data acquired in 2003. Main engine types, fuel types, operations types, navigation times and speeds of vessels are taken into consideration in the study. Total emissions from ships in the study area were estimated as 5,451,224 t y− 1 for CO2, 111,039 t y− 1 for NOx, 87,168 t y− 1 for SO2, 20,281 t y− 1 for CO, 5801 t y− 1 for VOC, 4762 t y− 1 for PM. The shipping emissions in the region are equivalent to 11% of NOx 0.1% of CO and 0.12% of PM of the corresponding total emissions in Turkey. The shipping emissions in the area are 46% of NOx, 25% of PM and 1.5% of CO of road traffic emissions in Turkey data between which and correspond to a higher level than aircraft emissions and rail emissions in Turkey.
