Abstract: The transition to sustainable tourism in the European Union (EU) is increasingly shaped by green and digital transformation. However, the efficient use of local natural, cultural, human, and technological resources remains vital for enhancing sustainability and improving quality of life. This article examines how smart tourism destinations can operationalize sustainability through data-driven tools, stakeholder collaboration, and territorial assets. Using the SMART Sustainability Framework, it analyzes key indicators such as tourism intensity, digitalization levels, and green initiative adoption, with a focus on newer EU Member States. Case studies from Ljubljana, Gothenburg, Valencia, and Madeira illustrate varied approaches to integrating local resources via ICT, participatory governance, and sustainable mobility. Comparative analysis highlights significant disparities, with High Performers like Slovenia and Spain aligning digital innovation with local sustainability goals. The article concludes with policy recommendations to strengthen local capacities, scale digital tools, and promote place-based strategies for more inclusive and resilient tourism development.
