Glaser (Eds.): Biochar in European soils and agriculture. Science and practice. London, New York: Routledge, pp. 184–204.
"To address the real contribution of thermally coverted biomass for greenhouse gas mitigation, it is necessary to assess the whole life cycle from the production of the biomass feedstock to the actual distribution and utilisation of the biochar produced in a regional context."
