FOREST BIOMASS RESIDUES AND THEIR USE TO MITIGATE CLIMATE CHANGE IN NORTH-CENTRAL SWEDEN

摘要

In this paper, we estimate the forest biomass growth and potential harvest of forest biomass residuesfor different climate and management scenarios (Reference, Current, Environment, Production, and Maximum) innorth-central Sweden, and the potential reduction of CO2 emission due to fossil fuel replacement. An integratedmodel-based approach is applied to estimate forest biomass production and substitution, considering the effects ofclimate change and forest management. The results show that the forest biomass residues may increase up to 89% andthe potential harvest by 64% in the next 100 years in J?mtland and V?sternorrland counties. If the potential harvest ofbiomass residues is used to replace fossil coal the net annual reduction of CO2equiv emissions could be up to 4.8 Tgin the year 2010, and could increase to 7.8 Tg in 2110 in J?mtland and V?sternorrland counties. The carbon stock instanding biomass, forest soils and wood products all increase, but the carbon stock changes are less significant thanthe substitution benefits.
