Balancing economy, social justice, and environmental protection while achieving decarbonisation and adapting to climate change poses a significant challenge for nations, regions, and cities. The Sustainable Development Goals and the Sustainable Energy and Climate Action Plans are widely used plans designed to oversee mitigation and adaptation actions. However, despite the common topics addressed by both, the absence of a common framework and the multiplicity of indicators proposed imply an extra effort in their implementation and evaluation, as well as the difficulty of evaluating peer benchmarking. Hence, this review focuses on identifying frequently proposed indicators, highlighting potential links among metrics and establishing a list of potential indicators. The bibliographic analysis conducted allowed the identification of more than 80 sources and 410 different metrics. The study reveals the diversity of approaches chosen to define a set of indicators and underscores the need for a harmonised framework to effectively compare and monitor European regions and cities. Moreover, thanks to this study, a list of potential indicators and the methodology for populating them was established, allowing better coherence among the initiatives and a starting point for small regional and local administrations that often struggle with the availability of data and resources.

The Retabit platform is a data-driven tool designed to bridge the gap between building rehabilitation and urban regeneration by integrating energy, economic, and social dimensions into a single framework. Leveraging multiple public data sources, the platform provides actionable insights to local and national authorities, public housing agencies, urban planners, energy service providers, and research institutions, helping to align renovation initiatives with broader urban transformation goals and climate action objectives. The platform consists of two main components: Analyse, for examining building conditions through multidimensional indicators, and Plan, for designing and simulating renovation projects. Retabit contributes to more transparent and informed decision-making, encourages collaboration across sectors, and addresses long-term sustainability by incorporating participatory planning and impact evaluation. Its scalable structure makes it applicable across diverse geographic areas, policy contexts, and domains linked to sustainable urban development.
