This paper discusses the concept and how to evaluate Urban SUNstainability. Generically understood as a process for attaining sustainable development in urban areas, via the intense production and use of solar energy, Urban SUNstainability is presented as a convincing urban policy strategy for a greener, sustainable and prosperous world. Based on existing experiences in areas with abundant levels of solar radiation, it was found that, by now, the use and production of solar energy in urban areas starts to be economically viable and should be regarded as an adequate solution to implement a greener and sustainable territorial development process in urban areas. As a way to assess the potential and current levels of Urban SUNstainability in urban areas, the paper proposes a multi-dimensional policy evaluation framework, based on five crucial aspects: the solar energy generation capacity, the direct and indirect environmental, economic and social benefits from implementing Urban SUNstainability strategies, and the soundness and effectiveness of the urban planning and governance processes related to the implementation of this process.
