The purpose of SUPERGREEN is to promote the development of European freight Logistics in an environmentally friendly manner. Environmental factors play an increasing role in all transport modes, and holistic approaches are needed to identify win-win solutions. SUPERGREEN will evaluate a series of Green Corridors covering some respective regions and main transport routes throughout Europe. The adopted methodology involves the following steps:• The selected corridors will be benchmarked based on parameters and KPIs covering all aspects related to transport operations and infrastructure. Based on the benchmarking exercise areas and conditions for improvements will be identified (i.e. bottlenecks);• The next step will be to evaluate how green technologies may support improving the identified bottlenecks. Among the green technologies may be novel propulsion systems, alternative fuels, new cargo handling technologies, etc.• The benchmarking is an iterative process which depends on "smarter" utilization of available information in the multi-modal chain (ICT-flows). An analysis will be made on how this information can be utilized to achieve greener logistics along the green corridors.• Based on these iterative benchmarks and evaluations, new R&D within specific topics may be needed to improve the identified bottlenecks. Recommendations for future calls for R&D proposals will be made.• Last but not least, the SUPERGREEN project will review and address the implications of alternative policy measures for green corridors, at both the Local and European Levels.
