The megaregion is key to localising the European Green Deal and achieving the EU's ambitions to become a neutral-climate continent. The workshop by the SURE-Eurodelta Network will focus on presenting concrete spatial and policy-oriented actions, especially in the field of sustainable transport infrastructure and mobility. The SURE partners from four countries will showcase their best practices in response to European Green Deal. Additionally, the outcomes and recommendations from the ESPON STISE Research will be presented, as well as the bright ideas from the Eurodelta Knowledge Platform. During this session we will launch a discussion on the added value for the European Member States and other megaregions, in terms of supporting cross-border cooperation. During the workshop, various stakeholders will be able to address their challenges and impacts with green transition plans. The aim is to create a sustainable, green, just, productive delta region.
