A baseline assessment, an impact and vulnerability assessment of EU investments in infrastructure and a mitigation potential analysis shall help to generate policy options, which will be appraised in the subsequent phase of the project. In this report we set the stage for the further tasks. The report identifies critical questions and resulting implications concerning the assessment of impacts and vulnerability of infrastructure and infrastructure investments in the EU; describes EU Cohesion Policy; o details the current design of the Structural Funds; describes the issue of environmental and climate change mainstreaming from an EU perspective; presents an exploratory analysis of evidence for climate policy integration based on Member States National Strategic Reference Frameworks (NSRFs); and finally addresses the main research and knowledge gaps that will be addressed in subsequent research within this work package
