The Rostock Energy Alliance (Energiebündnis Rostock) was founded in April 2011 by the City of Rostock and nine other municipal stakeholders from sectors such as public transport, housing and waste and water management. Their united goal is a locally based energy supply fully sourced from renewables. While CO2 emissions should be reduced, quality of life should not. The Alliance meets face-to-face biannually to exchange knowledge and experience, as well as to seek synergies for various constituent activities. The Alliance aims to reduce the annual CO2 emission per person to 2.5t or less by 2030. Compared to 2010, this is equal to a 2% reduction per year. To date (2015), the Energy Alliance supported the city in the creation of an energy transition concept and the current implementation of associated measures, in addition to the foundation of an energy cooperative.

This assessment report gives an overview of the key indicators for the POCACITO (Post-Carbon Cities of Tomorrow) case study of Rostock. This mid-sized city is located in Central Europe on the north-east coast of Germany. Rostock is a regional centre and coastal city. The assessment provides an outline of some of its main challenges and opportunities. The report was used in the POCACITO project for workshops with stakeholders in Rostock on vision building and back-casting to derive a 2050 roadmap as well as a scenario modelling on Rostocks measures for climate change mitigation.

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.

The Ecologic Institute is responsible for concept, design, programming and content of the POCACITO project website. The website provides information on the project, the case studies and the project results. There is also a "marketplace of ideas", where users can search for specific information by filtering the topics, locations and population. An interactive map then shows the accompanying cities. Furthermore all news about the project can be found in the blog on the website.

On 18 November 2016, the ELEEP Network and the POCACITO project hosted an official COP 22 side event in Marrakech on the topic "Transatlantic Perspectives on Integrating Climate Mitigation and Adaptation in Cities".

The final conference of the project "Post-carbon cities of tomorrow" (POCACITO) led by Ecologic Institute, will take place on Friday, 21 October 2016 in Brussels. At the interactive conference we will present our experience in developing long-term strategies with stake-holders through visioning and backcasting workshops and other results of the project, such as a high level document or 'roadmap' to achieve livable post-carbon cities by 2050. Registration is now open!

The workshop "Rostock 2050 - Measures for a post-carbon city, was the fourth and final workshop held in Rostock as part of the project Post-Carbon Cities in Europe: A Long-Term Outlook (POCACITO). In this workshop, the results of the modelling excercise undertaken by the POCACITO team were presented to and discussed with the stakeholders of the participation process in Rostock. The modellers had quantified the decided-upon measures and the ambitious measures of the post-carbon vision elaborated in the previous workshops. The results were presented in a "business-as-usual 2050" and a "post-carbon 2050" scenario. Learing from these results the participants dicussed the gaps remaining on the trajectory to a post-carbon future and which areas should be prioritized to be successful. Furthermore, a focus was on the question, how the EU or the national level could help the city of Rostock to reach its post-carbon goals.

Cities are at the forefront of the global carbon revolution, breaking established structures and creating new models for integrated systems. At an official side-event at COP21 in Paris, members of the POCACITO project consortium, including Max Gruenig and Camilla Bausch from Ecologic Institute, discussed how cities, serving as hubs of knowledge and learning, are essential catalysts in the global transformation to a post-carbon society.

As part of the visual identity for project "Post-Carbon Cities in Europe: A Long-Term Outlook" (POCACITO), Ecologic Institute designed a promotional flyer in small postcard format. The flyer summarizes general objectives and aims of the project, is styled according to the project style-guide and also contains a list of partners, contact information and a QR-code directing to the project website. Flyers are distributed during project events.

The EU has stated its commitment to transitioning into a post-carbon society. Though the goal of living in a post-carbon society is clear, the road to get there is not so easy. How can we build the EU of the future while overcoming technological, political, societal, economic and behavioural challenges? The Research for a Post-Carbon Future conference on 17 September 2014 explored ways to transform these challenges into opportunities and help propel the EU towards a more sustainable future.

In the transition to a post-carbon economy and sustainable societies, cities will be faced with unique challenges. POCACITO focused on uncovering how to improve the resilience of cities and regions in order to reduce existing and emerging conflicts over resources and their use in light of societal mega‐trends, environmental deterioration and climate change.
