“…On the contrary, if the forest residues are not burnt, they decompose and emit carbon gradually, so that their emission is not avoided. On the other hand, unless fossil fuels are burnt, carbon remains stocked in the ground and it is not released [63], which is an advantage of the use of biomass fuel in relation to fossil fuels. It also adds value to waste materials [64].…”

The substitution of energy based on fossil fuel by bioenergy could be an effective solution to reduce external energy dependency, thereby promoting sustainable development. This article details a study of the use of biomass residues produced in the forestry sector as a consequence of field operations of the two predominant forest species (Pinus radiata D. Don and Ecualyptus globulus Labill) of Biscay (Spain). The potential of forest residues is estimated to be 66,600 dry Mg year − 1 . These residues would provide 1307 TJ year − 1 . Energy parameters, ultimate and proximate analyses, and the level of emissions of the forest residues are performed in order to estimate their characteristics as fuel. The research done has shown very similar values in terms of the net calorific value of the residues of P. radiata (19.45 MJ kg − 1 ) and E. globulus (19.48 MJ kg − 1 ). The determined emission factors indicate a reduction in gas emissions: CO (23–25%), CO 2 (22–25%), SO 2 (87–91%) and dust (11–38%) and an increase of 11–37% in NO x compared to hard coal. Estimation of the emission factors of the residual biomass allows the environmental impacts, that are potentially produced by biofuel, to be estimated.

“…The study by Repo et al (2015) showed that forest bioenergy may have significant climate impacts because the time lag between carbon loss in combustion and carbon sequestration of the new tree generation takes decades. Finally, as concluded by Rautiainen et al (2018), in addition to time preference and the social cost of carbon, the climate impact of forest residues also depends on the type of energy source that the forest bioenergy is compared with, such as coal or natural gas, as the carbon contents differ. According to the Intergovernmental Panel on Climate Change (IPCC) guidelines, carbon dioxide emissions from biomass combustion can be counted as zero in the energy sector if these emissions are taken into account in the land use, land use change and forestry sector (LULUCF) (IPCC 2006).…”

“…Forest biomass has been previously regarded as a carbon neutral or low-carbon energy source, as carbon dioxide emissions from biomass combustion are compensated by the growth of new tree generation (e.g., Stupak et al, 2007). However, the climate impacts of forest bioenergy have been found to depend on various aspects, such as the regulator´s time horizon and preference and the social cost of carbon as a measure of damage (Repo et al 2011;Repo et al 2012;Rautiainen et al 2018). Furthermore, the climate impacts of forest biomass depend highly on the type of biomass considered.…”

“…Furthermore, the climate impacts of forest biomass depend highly on the type of biomass considered. Climate impacts of burning stumps are much higher than, for example, the impacts of burning small branches and foliage (Repo et al 2012;Rautiainen et al 2018). The study by Repo et al (2015) showed that forest bioenergy may have significant climate impacts because the time lag between carbon loss in combustion and carbon sequestration of the new tree generation takes decades.…”

This dissertation develops a framework to examine socially optimal forest management when nutrient and sediment loads from forestry are considered as a negative externality. The Faustmann rotation model is extended to include the runoff function to describe the water quality impacts of nutrient and sediment loads from forestry.This thesis consists of an introductory section and four articles that analyze the different forest management practices and associated water protection. Examined practices include final harvesting in both mineral soils and peatlands, stem-only harvesting and whole-tree harvesting in peatlands, and ditch network maintenance. The water protection measures included are buffer zones in mineral soil forestry and overland flow fields and sedimentation ponds in drained peatlands.The main contribution of this thesis is the developed framework for analyzing socially optimal forest management when water quality is taken into account. The analysis shows that the nutrient and sediment load damages associated with forest management depends highly on management practices. The nitrogen load caused by final harvesting in mineral soils results in relatively low nitrogen load damages. In contrast, the sediment load damages due to ditch network maintenance in the sensitive headwater catchment are very high. Furthermore, the cost-effectiveness of water protection measures differs significantly. From society´s viewpoint, the buffer zones used in mineral soil forest management are not a costeffective water protection measure but when biodiversity benefits are taken into account, in addition to water quality, they become socially desirable. Overland flow fields are very costeffective water protection measures for peatland forestry. Finally, the water protection costs in forestry and agriculture are compared in a river basin model. A cost-effective solution requires the highest nutrient reductions in agriculture, though it also implements water protection measures, especially in drained peatland forestry.
