Greenhouse-gas emission mitigation has been estimated for the use of existing and mature biomass
technologies. A general methodology has been developed to determine potential amounts of residues that
can be made available for energy purposes and the resulting fossil-fuel replacement from utilization of
these residues. The consequent reductions in CO2, CH4 and N2O emissions in CO2 equivalents for a time
horizon of 20 years, as well as costs of abatements, were calculated. Both traditional and improved energy
uses are considered. Ó 1998 Elsevier Science Ltd. All rights reserved.
