Sustainability transitions are a significant challenge that requires established industries to adopt innovative ways of doing business. Research suggests that while this is possible through business model innovation (BMI), risk avoidance by regime actors and high levels of future uncertainty act as barriers to successful transitions. Specifically, we lack knowledge about how established companies innovate their business model (BM) to reduce uncertainty related to sustainability transitions. We explore the case of a large forest-based manufacturing company in the construction industry, Stora Enso. We find that, by pursuing transformative BMI and combining multiple value creation logics, a company can reduce different types of uncertainty while shaping its business ecosystem towards more sustainable opportunities. We show that the BM can serve as an organizational tool for collectively exploring new knowledge, reducing uncertainty and driving change in a business ecosystem.
