    Resumé

    Luftforurening fra brændeovne med PAH, primære partikler og klorerede dioxiner (anført p.g.a. nationale estimater af DMU) er fremstillet som et uløseligt problem p.g.a. dioxinernes de-novo-syntese i skorstenene, som den er kendt fra kommunale affaldsforbrændingsanlæg. En modregning af denne lokale forurening mod påståede positive indvirkninger af afbrænding af træ (som al biomasse) på den globale klimaforandring p.g.a.' nulstillede kuldioxid emissioner' afvises, selvom denne nulstilling er del af den danske lov om CO2-kvoter fra 2004. Disse emissioner forværres tværtimod per energienhed, når fossile brændsler erstattes, mens kompensrende binding af kuldioxid gennem trævækst over mange årtier er henvist til en usikker fremtid med global opvarming. Udtagne træprodukter skulle hellere ikke bruges i atmosfæriske brændere, men i produktform. En forøget udtagning af træ fra skovene kan risikere at underminere skovenes funktion som 'sinks' for kuldioxid, som forskningsresultater fra østrigske social-økologer viser, der er blevet til på baggrund af historiske langtids-analyser vedrørende skovareal og tæthed siden 1830 fordelt på sogne.
