The paper discusses problems related to transport infrastructure in the Russian Arctic, including one of the most important international transport corridors, the Northern Sea Route. We have established that Arctic ports are one of the weakest components of the transport corridor of the Northern Sea Route. We have carried out comparative analysis of the main ports and their infrastructure, considering the possibilities for developing the Northern Sea Route as part of the infrastructure of a green transport corridor. We have constructed a strategic map for the green transport corridor (i.e., a sustainable transport system including five components: sustainability, stakeholders, industry and entrepreneurship, qualifications and personnel, financial resources and budget). Causal relationships between the components have been found and key performance indicators for the sustainability component have been formulated.
