Climate impact assessments of forest bioenergy affected by decomposition modelling – comparison of the Q and Yasso models

The objective of this IEA Bioenergy Task 38 / Task 43 report was to analyse the importance of the choice of decomposition model for the estimate of the forest carbon and climate effects of extracting types of forest harvest residues, for example, stumps and branches of different diameters and using them for bioenergy. Further, differences in the model concepts and parameterisations were analysed. The climate effect was estimated based on a life cycle analysis (LCA) using radiative forcing metrics.
