Abstract: Management of the world’s forests can play a role for climate change mitigation by increasing CO2 storage in vegetation biomass and harvested wood products, and by displacing CO2-intensive materials such as steel or concrete. This study aimed to determine how management of boreal forest stands can contribute to climate change mitigation in the context of ecosystem-based management. The study was based on the comparison of different strategies applied to a balsam fir-white birch stand in the Eastern boreal forest of Quebec (Canada). We simulated five scenarios over a 199- year period at the stand level: a reference scenario involving clearcut at 50-year intervals, and four 12 alternative scenarios clearcut with longer rotation length (70 and 80 years), partial cut, and a no harvest scenario. Overall, scenarios with longer clearcut rotations and, to a lesser extent, partial cut resulted in a higher potential to mitigate climate change. The substitution effect of wood products was revealed as a key aspect, suggesting that wood product manufacturing and utilisation on the markets, and not only forest management, need to be carefully considered.
