In early February 2016, the American Red Cross has initiated a process of taking stock of tools and approaches being used/developed for urban assessment and agree on a plan of action leading to development of an aligned Urban Assessment toolbox for NSs and their partners. As a result of this process, several case studies were developed and a workshop was organized in Copenhagen hosted by the Danish Red Cross on 20-21 June, 2016 with the participation of 15 National Societies, GDPC, RCRC Climate Center and partners such as ALNAP, ACAPS and IRC. This report documents the results of the workshop and the agreed action plan for the follow up process.
