This study examines the complex interplay and relationships between national climate–, energy– and nature conservation policy within the framework of offshore wind power development in Sweden. Focusing on the potential conflicts and synergies between these policy areas, the research applies theories of Policy Integration (PI) and Environmental Policy Integration (EPI) to clarify the integration between the policy areas and whether environmental concerns are prioritized. The energy sector is developing rapidly in response to the challenges of climate change, with offshore wind power emerging as a central component in sustainable energy transitions. However, the expansion of offshore wind power poses a potential threat to marine biodiversity. The study uses a qualitative content analysis of selected national policy documents in the areas of climate, energy and nature conservation to identify important goals and concepts. The results reveal synergies between climate and energy goals, demonstrating a common motivation to reduce greenhouse gas emissions and transition to renewable energy sources. Nevertheless, conflicts arise in the energy policy area, highlighting tensions between economic benefits and the responsible use of marine resources. Marine biodiversity conservation policy exhibits strong environmental policy integration, which emphasizes the paramount importance of environmental considerations in decision-making. This research offers practical insights for policymakers navigating the intricate landscape of offshore wind deployment while emphasizing the need for a balanced approach that takes into account economic, climate and biodiversity objectives.
