DUAL Ports aims to decarbonise Regional Entrepreneurial Ports (REPs)´ resources through a shared eco-innovation port programme that minimises their environmental footprint.The objective is to specifically develop sustainable utilities and abilities of REPs. This will be achieved by collaboratively piloting and managing technologies and processes that tackle targeted measurable direct/indirect emission/pollution sources.The project will ultimately enhance ports organizational/operational (energy) efficiency and performance, facilitating port low carbonization at reduced cost and with knowledge/investment added value.As demonstrated by last years´ offshore wind energy developments in EU & beyond, ports can be key centres of innovation, testing and uptake of emerging technologies, leveraging participation and multiplier effects, e.g. by triggering value-for-money clustered activities that generate employment and benefit the environment. A transnational approach will be adopted to allow the DUAL small & medium size ports capitalise on this potential, overcoming their individual limited staff, funding and capability to identify the most effective solutions on their own. Only few measures have been selected due to the project duration and size of the partnership, but they are expected to have a considerable impact on the way ports can act as facilitators between enterprises, research centres and public authorities to enable user-driven eco-innovation in the North Sea area.
