The 2030 Agenda for sustainable development emphasizes the interconnectedness of environmental issues with socio-economic development, recognizing their fundamental role in human prosperity, while the sustainable development goals (SDGs) serve as a pivotal framework globally. This study provides a critical assessment of the progress made by EU Member States in pursuing the SDG 11 (sustainable cities and communities) targets as set out in the 2030 Agenda. The analysis is based on official data published by the EU Statistical Office—Eurostat—and uses the AAA (Holt-Winters) exponential smoothing algorithm for the trend analysis of specific indicators. The results show significant progress during the first seven years of implementation of the Agenda 2023, while indicating concerns about the achievement of the 2030 targets in some Member States. The mapping of potentially negative trends emphasizes the need for firm corrective actions, underlining the urgency of early interventions to address expected negative developments before they have potentially irreversible consequences.

This study explores the complex relationship between innovation and carbon dioxide (CO₂) emissions across the primary, secondary, and tertiary sectors within the 27 European Union (EU) member states over the period 2017–2023. Drawing on a comprehensive dataset and grounded in theoretical frameworks, the research investigates how different innovation indicators—including broadband penetration, digital skills, public and business R&D expenditure, ICT training, and SME-driven innovations—affect sectoral CO₂ emissions. Using robust regression, the findings reveal a nuanced landscape: while ICT skills training, human resource mobility in science and technology, and SME business process innovations are associated with significant reductions in emissions, certain R&D investments and broadband penetration display positive correlations with emissions in specific service-oriented sectors. These results suggest that the environmental impacts of innovation are highly context-dependent and not uniformly positive. This study highlights the importance of strategically aligning innovation policies with sustainability objectives. Policymakers are encouraged to promote targeted digital training, support environmentally conscious R&D, and foster SME-led innovation practices. The results contribute to the growing discourse on sustainable innovation and provide actionable insights to advance the EU’s green transition.
