Consequences of increased extraction of forest fuel; Konsekvenser av ett oekat uttag av skogsbraensle

Abstract

The Swedish Energy Agency research program 'Sustainable supply and processing of biofuels', also known as Fuel program, ran from 2007-01-01 to 2011-06-30. The results of the program are reported in synthesis reports for the different sub-areas. The purpose of the synthesis reports is to compile knowledge in various areas, to identify knowledge gaps that need to be addressed further, and to place and discuss the aggregated research results in a larger energy and societal perspective, including environmental quality goals and forest policy environmental and production goals. This report covers sub area 'Forest fuel and environmental impacts' conducted in 2007-2011. Biomass from forests, e.g. logging residues, has become an increasingly more important energy resource over the last decades. There is a strong ambition from the society (the Swedish parliament, European Union etc.) to increase the proportion of renewable energy in the energy system and decrease the use of fossil fuel. However, by increasing biomass extraction from our forests a number of environmental services, as well as future forest production will be affected. In this report we discuss if it is possible to increase biomass harvesting, how to combine biomass extraction with sustainable forestry including conservation of environmental services, and if there  More>>

The purpose of the synthesis reports is to compile knowledge in various areas, to identify knowledge gaps that need to be addressed further, and to place and discuss the aggregated research results in a larger energy and societal perspective, including environmental quality goals and forest policy environmental and production goals. This report covers sub area 'Forest fuel and environmental impacts' conducted in 2007-2011. Biomass from forests, e.g. logging residues, has become an increasingly more important energy resource over the last decades. There is a strong ambition from the society (the Swedish parliament, European Union etc.) to increase the proportion of renewable energy in the energy system and decrease the use of fossil fuel. However, by increasing biomass extraction from our forests a number of environmental services, as well as future forest production will be affected. In this report we discuss if it is possible to increase biomass harvesting, how to combine biomass extraction with sustainable forestry including conservation of environmental services, and if there are any threshold values for avoiding negative impact. The report mainly covers consequences of extracting logging residues, such as branches and tops (in Swedish this is summarised as grot), and stumps. Connected to this we also discuss effects of ash recycling. We also discuss intensive forestry including plantations with short rotation and nutrient optimisation. At present this is only carried out in a small scale for research purpose, but might be a possibility in the future. Finally, we analyse consequences of peat extraction, but only consequences for biodiversity. At the moment peat harvesting is of limited importance in Sweden, but it might increase and it is often mixed with other solid biofuel at the plants. The review is based on a large number of scientific reports. It focuses mainly on Swedish conditions, consequently studies from northern Europe dominates, but we refer also to a large number of studies from other parts of the world. In Sweden, most of the relevant studies have been financed by the Swedish Energy Agency. Therefore, we have analysed all projects within the research programmes funded by the Swedish Energy Agency. This means not only reading scientific papers, but also all kinds of reports, as well as interviews with project leaders. Our result has been examined and discussed at a number of seminars and workshops. Connected to our work we had a reference group with members representing authorities, forestry companies and NGOs. To be able to evaluate the consequences of increased biomass extraction we have related our result to environmental objectives, and goals for forest production, set up by the society (the Swedish parliament). In Sweden we have adopted 16 environmental objectives (http://www.miljomal.nu/Environmental-Objectives-Portal/, in English). Of these especially five objectives are most relevant for our analysis: Reduced climate impact, Natural acidification only, A non-toxic environment, Zero eutrophication and Sustainable forests. The forest production goal is described in the forestry policy (Government proposition 1992/92: 226, in Swedish)}
