Intermediaries to accelerate the diffusion of wooden multi-storey construction in Finland

Intermediaries can potentially help reduce institutional lock-ins that slow down sustainability transitions by influencing policy processes, because of their connectedness and often high level of legitimacy. In this paper, we analysed intermediaries seeking to accelerate the diffusion of wooden multi-storey construction (WMC) in Finland, their roles and engagement in policy processes. Increasing the use of wood in construction has high policy support nationally, backed up with climate and forest policies. Yet, market diffusion has been slow. The data consist of qualitative interviews of intermediaries and other actors, participatory observation and a review of secondary materials. The results reveal a complex set of intermediaries, including systemic, niche and regime-based ones. The intermediaries are characterised by multiple goals, partly overlapping roles and means of policy influencing. The low degree of coordination among the intermediaries and the differences in their agenda for transition are critical challenges which limit the effectiveness of their actions.
