The objective of MERMAID is to establish a state-of-theart of environmental monitoring systems operated by urban ports. The project will review the best practices of ports and set up a list of environmental paràmetres (air pollution, noise, water quality, etc.) that need to be monitored. The project include studying around 20 ports and visiting 6 ports which have implemented an environmental monitoring system with the objective to know what are the sustainability and communication policies of the port authorities regarding environmental issues. Finally, it includes a guideline to encourage European ports to deploy these best practices. Expected Results: • MAPPING OF PORTS WITH ENVIRONMENTAL MONITORING SYSTEMS The deliverable provides a map locating the ports studied and visited equipped with an environmental monitoring system. • DATABASE OF INDICATORSThe database of indicators provides a list of the environmental parameters that are studied and monitored in more than 80 ports.• DATABASE OF APPROPRIATE TECHNOLOGICAL SOLUTIONS The database of technological solutions provides a non-exhaustive list of existing technologies used by European urban ports to measure environmental pollutions related to air, water, and noise as well as energy consumption• REPORTING & SUCCESS FACTORS FOR ENVIRONMENTAL MONIROTING SYSTEMSThe deliverable consists in a summary of all the information collected during port visits. For each one of the visited port, the document describes information regarding different aspects: Sustainability and communication policies of the port authority regarding environmental issues; Environmental management system; Environmental monitoring (air quality, noise, water quality, wastes, energy) The report also shows a comparative analysis between ports, for each of the environmental aspects subject to monitoring.• STRATEGY AND WORKING PAPER Taking into account the studies and the visits of urban ports, the objective of the Strategy and Working Paper is to provide recommendations addressed to port authorities wishing to implement an environmental monitoring system and recommendations for the orientations of the 2014-2020 MED Programme.
