Cities demand strategic projects and sustainable indicators to improve the citizen quality of life. The research objective investigates how sustainable city strategies in Curitiba, Brazil, align with the United Nations Sustainable Development Goals (SDGs), offering
valuable insights for urban planners, policymakers, and academic institutions. Based on open public data and employing a case study methodology, the research analyzes 29 municipal strategies categorized into environmental, social, and economic components. Findings reveal a high correlation between the strategies and SDG 11 (Sustainable Cities and Communities) and SDG 17 (Partnerships for the Goals), with 100% alignment. A moderate correlation trend is identified with SDG 3, SDG 10, and SDG 12, while the remaining twelve SDGs show lower levels of association. These results emphasize the multidimensional nature of sustainable urban planning and the varying degrees of integration across different SDGs. The research concludes that when city strategies are tailored to local contexts and supported by institutional collaboration, they can become effective mechanisms for fostering environmental stewardship, social equity, and urban economic resilience. The conclusion reiterates how localized planning can drive global sustainability agendas and highlights the importance of strategic alignment between urban policy and international development frameworks in the Strategic Digital City context.
