Energy efficiency coefficient as a tool for determining the carbon footprint from the operation of sea-going ships of ice classes

The paper deals with the issues of determining the carbon footprint of transport services when using ships with an ice class operating on Arctic routes. The aim of the study is to identify alternative methods for assessing the constructive coefficient of efficiency of ice ships for its further use for corporate accounting of carbon units, determining the carbon footprint of a transport service, as well as assessing the impact of weather conditions along the Northern Sea Route on the carbon footprint left by a ship passed from the Gulf of Ob to the eastward during summer and autumn. The study provides recommendations on the use of methods for calculating the carbon footprint of a transport service, based on the constructive coefficients of the energy efficiency of ships, allowing the use of the methodology for solving problems of planning the activities of transport companies aimed at modernizing the fleet and deriving profit from the set of core activities and participation in the newly formed trade in carbon units.
