The Blue Economy, with its emphasis on ocean-based industries, is critical for achieving sustainable development. This study investigates the intricate relationship between sustainability, innovation, and their economic, environmental, and social impacts within Portugal’s Blue Economy. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to test the hypothesized relationships between sustainability, innovation, and triple bottom line (TBL) outcomes based on survey data from firms operating in the sector. The findings confirm that innovation acts as both a direct outcome of sustainability efforts and a mechanism for mediating its impacts on economic and environmental performance. However, no significant direct or mediating effects were observed for social outcomes, highlighting a persistent gap in this dimension that requires further research. The study contributes to both theory and practice by highlighting the strategic integration of sustainability into organizational innovation processes and its role in enhancing multidimensional performance. By identifying critical pathways and barriers, this study offers valuable guidance for policymakers and industry leaders striving to enhance the long-term sustainability of the Blue Economy.
