[en] The POLIS project invites local authorities in different states of urban development to collaborate with each other in order to share their experiences and knowledge of solar town planning. Within the framework of POLIS project, six European cities (Lyon and Paris in France, Munich in Germany, Lisbon in Portugal, Malmoe in Sweden and Vitoria-Gasteiz in Spain) have committed on long-term strategies to integrate solar energy at urban level that are consistent with existing CO₂ mitigation targets in solar Action Plans embedded in local planning. Although the cities are in different situations regarding solar energy so that their strategies are also different, a common objective is shared, namely, to steer the future development of solar energy with respect to urban planning by: the assessment of existing climate strategies and targets at city levels, the evaluation of solar potential in city areas, the development of solar targets and the definition of possible measures in diverse planning areas connected to general renewable energy targets. In this report an overview of POLIS cities long-term solar targets is presented. These targets have been established in solar Action Plans defined by Local Working Groups composed by municipalities and technical partners of POLIS project. More information about the solar Action Plans can be found in the report 'Deliverable 4: Action Plans in POLIS cities'
