“…2). The Q model was initialised with a steady state assumption with the parameterisations used in Ortiz et al [34]. This means that in the first year (2010), the litter input to the soil was equal to the decomposition rate.…”

“…The Q model has been calibrated and validated for Swedish conditions, resulting in parameter uncertainty ranges [34]. The Q model simulates organic carbon and continuously tracks different fractions/qualities of organic material that decompose at a certain rate depending on the quality of the material at a given time.…”

“…The problem is the same as for repeated measurements: the predicted changes in soil organic carbon are small compared to the soil organic carbon pool. Parameter uncertainty and uncertainty in input variables like, e.g., litter fall leads to uncertainty in the predictions which in many cases prevents conclusive results about the direction of change (Ortiz et al 2011). …”

The climate mitigation potential of using logging residues (tree tops and branches) for bioenergy has been debated. In this study, a time-dependent life cycle assessment (LCA) was performed using a single-stand perspective. Three forest stands located in different Swedish climate zones were studied in order to assess the global temperature change when using logging residues for producing district heating. These systems were compared with two fossil reference systems in which the logging residues were assumed to remain in the forest to decompose over time, while coal or natural gas was used for energy. The results showed that replacing coal with logging residues gave a direct climate benefit from a single-stand perspective, while replacing natural gas gave a delayed climate benefit of around 8-12 years depending on climate zone. A sensitivity analysis showed that the time was strongly dependent on the assumptions for extraction and combustion of natural gas. The LCA showed that from a single-stand perspective, harvesting logging residues for bioenergy in the south of Sweden would give the highest temperature change mitigation potential per energy unit. However, the differences between the three climate zones studied per energy unit were relatively small. On a hectare basis, the southern forest stand would generate more biomass compared to the central and northern locations, which thereby could replace more fossil fuel and give larger climate benefits.
