In the White Paper on Transport 2011 the European Commission stressed the concept of green transport corridors, i.e. transshipment routes with concentration of freight traffic between major hubs and by relatively long distances of transport marked by reduced environmental and climate impact while increasing safety and efficiency with application of sustainable logistics solutions. Green transport is based on inter-modality, powerful logistics hubs and advanced ICT-systems improving traffic management, increase efficiency and better integrate the logistics components of a corridor. Sustainable hub development along the transshipment routes of green corridors is one of the major tasks of green corridors in order to safeguard and meet the necessary corridor performance for the current and future transport demand. The main corridor hubs represent logistics clusters in the sense of Yossi Sheffi, comprising ports, logistics centers and other transshipment nodes. The paper will present results about the development of core logistics clusters representing hubs in green transport corridors and it will indicate actions for hub development with a future-oriented compilation of sustainable development measures of infrastructural, legal or organizational nature. Since the author took part in some important green transport corridor initiatives around the Baltic Sea, including “East-West Transport Corridor (EWTC II)” initiative, representing the first European project which delivered a green corridor manual formulating recommendations and requirements of green transport corridors to European level, some case studies from EWTC project will be discussed.
