METHODOLOGY FOR ESTIMATING GREENHOUSE GAS EMISSIONS FROM SHIPS MOVING IN ICE

The article presents a methodology for estimating greenhouse gas emissions by vessels navigating in the Arctic waters, both in open water and in the ice cover. The methodology is based on the combination of AIS data and ice charts with subsequent quantitative assessment of ice cover resistance to vessel movement. The proposed methodological tools ensure high accuracy in determining the emission load, including the specifics of navigation in Arctic waters, taking into account the dynamic characteristics of the ice situation. To verify the methodology, the annual greenhouse gas volumes for the vessels of the “Novy Port” project for 2024 calculated using the developed methodology have been compared with the emission volumes calculated based on the actually consumed bunker fuel.
