This booklet gives an overview of the POCACITO project, focussing on the methodology used and most importantly on the major findings, results and outcomes of the project. Cities are of outstanding importance in addressing climate change since they are not only the centre of economic and social initiatives, but also responsible for the majority of global energy consumption and for approximately 60% of global greenhouse gas (GHG) emissions. Stakeholders at the city level thus face significant challenges, which are addressed by the European research project Post-Carbon Cities of Tomorrow (POCACITO), funded by the European Union’s Seventh Framework Programme for research, technological development and demonstration. The POCACITO project facilitates the transition of cities to a sustainable or “post-carbon” economic and societal model in a global context. POCACITO uses a participatory approach that engages local stakeholders to create custom made transition strategies for ten case study cities. These strategies are then used to create a EU 2050 Roadmap, a stakeholder-driven guide towards the model “Post-Carbon City of Tomorrow” that merges climate, energy and social urban transitions.
