The effects of circular economy on biodiversity are poorly understood. This study provides observations on approaches for assessing circular economy and illustrates, with a Finnish case study, the potential of circular economy to mitigate pressures on biodiversity. The case study focuses on the construction and real estate sectors, as well as the forest industry. The findings imply that circular economy actions that reduce the extraction of virgin raw materials and relieve land use pressures are effective. Improving material efficiency, increasing the cascading use of wood, and optimizing the use and reuse of materials and products, as well as extending the lifetime of buildings and optimizing space use, have good potential for mitigating pressures on biodiversity in Finland. However, as forest utilization has a major impact on Finnish biodiversity, certain actions that possibly increase the use of forest resources (e.g., replacing fossil-based, concrete, or steel materials with wood-based solutions) may impair biodiversity if biodiversity-enhancing forest management practices are not utilized. Assessing the biodiversity impacts of circular economy is challenging, and the need for further research and the development of indicators and assessment methods is clear.

Using wood in multistory apartment construction (WMC) has a climate-positive advantage with buildings acting as long-term carbon storage. Business ecosystem (BE) development around WMC is needed to accelerate the adoption of wooden materials in the conservative construction industry. As the business actors around WMC are essentially different from those using other building materials, new knowledge must be built from the project level. This study uses a qualitative interview approach among actors from three pioneering urban building projects to address their perceptions of building with wood regarding a project-based BE. Based on the thematic analysis, sources of both tangible and intangible value creation were found to arise from building with wood. A higher degree of prefabrication associated with WMC was seen in all projects to influence the reorganization of logistics, enabling faster building processes and lean material use. No strong sustainability-driven culture could be identified in any of the projects. Results further flag the sensitivity and importance of management and coordination skills in targeting improvements of the construction business based on WMC. In the bigger picture, there is still room for further research at regional and global level on business model changes in building with this renewable and recyclable material.
