Sustainability has evolved from a buzzword to a critical imperative in addressing societal and environmental challenges. While economic and environmental dimensions of sustainability are widely acknowledged, the social dimension often receives less attention despite its significance. In this communication, we explore the concept of the Social Sustainability Index (SSI) and its relevance in understanding the sustainability image across European regions. By examining the conceptual framework of SSI and its application in regional contexts, we aim to elucidate the nuanced interplay between social sustainability and regional development [1].
The Social Sustainability Index (SSI) serves as a tool for quantifying and assessing the social dimensions of sustainability within a given context. Unlike traditional indicators that focus solely on economic or environmental metrics, SSI incorporates a wide range of social indicators, including education, healthcare, income distribution, social cohesion, and quality of life. By aggregating these indicators into a composite index, SSI provides a comprehensive measure of social well-being and inclusivity, offering insights into the overall sustainability performance of a region [2].
European regions exhibit considerable variation in social sustainability outcomes, reflecting disparities in economic development, governance structures, and social policies. SSI enables policymakers and stakeholders to identify regions with the highest social sustainability scores and those lagging behind, thereby highlighting areas for targeted interventions and resource allocation.
By incorporating SSI into policy formulation processes, European regions can prioritize social sustainability goals and integrate them into regional development strategies. This entails adopting policies and initiatives aimed at promoting social inclusion, reducing inequalities, and enhancing the well-being of all residents, irrespective of their socio-economic background [3].
SSI serves as a valuable tool for engaging stakeholders, including governments, businesses, civil society organizations, and local communities, in the pursuit of sustainability objectives. By providing transparent and standardized metrics, SSI facilitates dialogue, collaboration, and collective action towards shared sustainability goals, fostering a sense of ownership and accountability among stakeholders.
Several case studies exemplify the application of SSI in European regions and its impact on sustainability governance and policy-making. For instance, the European Commission's Regional Social Progress Index (SPI) assesses social sustainability across EU regions, informing policy decisions and resource allocation at the regional level. Similarly, initiatives such as the Social Progress Imperative's Social Progress Index provide valuable insights into the social performance of European countries and regions, guiding efforts to promote inclusive and sustainable development [4].
Despite its potential, the widespread adoption of SSI in European regions faces several challenges, including data availability, methodological complexity, and stakeholder buy-in. Addressing these challenges requires collaboration among policymakers, researchers, and practitioners to enhance data quality, standardize methodologies, and build capacity for SSI implementation. Looking ahead, emerging trends such as the integration of digital technologies and citizen engagement platforms hold promise for advancing the measurement and monitoring of social sustainability in European regions [5].
