Sustainable wood use, decarbonisation of energetic metabolism and forest development

    Research output: Contribution to conferencePosterResearch


    Air pollution from wood stoves with PAH, primary particles and chlorinated dioxins (reported according to national estimates of  Danish NERI) is presented as an insoluble problem because of dioxin de-novo-synthesis in chimneys, as it is known from municipal waste incinerators. A trade-off of this local pollution against alleged positive impacts of wood (as all biomass) combustion on global climate change because of 'zero carbon dioxide emissions' is rejected, although this resetting to zero is part of the Danish Law on CO2-quota of 2004. These emissions are, on the contrary, aggravated pr. unit of energy, when substituting for fossil fuels, whereas compensatory binding of carbon dioxide by tree growth over many decades is referred to an insecure future under global warming. Harvested wood products should rather not be used in atmospheric burners, but in product form. Otherwise an accelerated extraction of wood from forests may risk undermining the carbon dioxide sink function of forests, as research results from Austrian social-ecologists show on the background of long-term historical analyses since 1830 of forest area and densities on parish level.
