Abstract
Sustainable forest biomass production constitutes a key component in the development of Swedens bio-based economy. In addition, forest management can counteract fossil fuel CO2 emissions by i) enhancing the C sink in biomass and soil, ii) increasing the C storage in wood products and iii) using biomass as a fuel and material substitute. The governmental assignment *Swedish Roadmap 2050* has been commissioned to propose a strategy to achieve the long-term vision of *zero net GHG emissions to the atmosphere in 2050*. Such strategy will require sustainable forest management practices that significantly reduce Swedish CO2 emissions. Currently however, the forest C sink strength is unknown since it is not possible to estimate the C balance of an entire forest landscape given its heterogeneity in stand age, species, site conditions and management history. To fill this gap, we will utilize a world unique set up that integrates state-of-the-art research tools including tall tower eddy-covariance flux measurements, 16 long-term monitored streams, 500 forest inventory plots, high-resolution Lidar scans and a 2x2m soil hydrology model over a catchment with replicated stands to provide an unprecedented estimate of the carbon balance of a managed forest landscape in boreal Sweden. This project will provide policy makers with valuable science based decision support, which can facilitate development towards a low carbon society.
