Emission Inventory of Marine Traffic for the Port of Zadar

This paper estimates the exhaust gases emissions from ships in the international marine traffic in the port of Zadar. The emission results refer to the pollutants such as nitrogen oxides (NOx), sulphur oxides (SOx), particulate matter (PM), volatile organic compounds (VOC) and greenhouse gases such as carbon dioxide (CO2). The methodology that has been applied, so called "bottom-up" approach, uses detailed data on ship's characteristics (engine power, the load factor, fuel type, the emission factor) and time spent cruising and hotelling. The estimated inventory for the port of Zadar includes overall marine traffic from the passenger and cargo terminals. The exhaust gases emissions have been divided into three ship's activities: cruising in the reduce speed zone, hotelling (at berth) and manoeuvring. The results (tons/year) have shown that approximately 80% of total emissions come from passenger ships and 20% from cargo ships.
