This research initiative was jointly launched jointly by the OMEGA Centre at UCL and the European Investment Bank Institute (EIB) under the latter’s STAges de REcherche BEI-EIB (STAREBEI) Research Programme with the support of an EIB grant. This 18-month study principally undertaken by one of the OMEGA Centre’s PhD students (Marco Dean) – under the supervision of the Director of the OMEGA Centre and an EIB Staff member – sought to develop a Policy-Led Multi-Criteria Analysis framework and attendant processes to facilitate more holistic and transparent approaches to the planning and appraisal of mega infrastructure gateway projects for major European seaport cities. The research findings from this study looked to contribute to the further development of PLMCA in the context of EIB appraisal practices, especially in relation to the appraisal of large-scale capital investments in seaport infrastructure, where a broader perspective can better highlight and address major investment risks and opportunities. The scope of work for this project has been considerably informed by earlier OMEGA Projects, namely OMEGA 1, OMEGA 2 and OMEGA 3 but also OMEGA 8 Projects.
