Timber construction can radically cut carbon emissions. The construction sector is accountable for c. 40% of global emissions, a third of which comes from the production of building materials. Replacing concrete and steel with timber offers a huge opportunity to reach the carbon neutrality goals. Nordic and Baltic countries have a unique advantage in leading the way, given the vast forest resources available, a long legacy of the forestry industry and wood building, the in-built industrial capacity, and the well-functioning and interlinked supply chains across the Baltic Sea Region (BSR). Yet, decisive policy measures are needed to overcome technical, regulatory, and cultural obstacles. Challenging the status quo and creating a market shift demands holistic and collaborative approaches that can enable systemic change, as well as targeted measures to navigate through country-specific obstacles.
