Ports are core nodes for multimodal transport in the Adriatic-Ionian basin and strategic key drivers for economic growth: reducing negative environmental impacts is essential for a sustainable development of the area. SUPAIR responds to a major challenge (EUSAIR strategy, pillar 2, topic 1), in that it tackles reduction of emissions from shipping and on-shore port operations with an integrated approach, enhancing port authorities’ capacity to plan and implement low-carbon and multimodal transport and mobility solutions and further empowering the main political, technical, trade stakeholders and partners in related decision-making.
