WEBThe use of coal is responsible for 1/5 of global greenhouse gas (GHG) emissions. Substitution of coal with biomass fuels is one of a limited set of nearterm options to significantly reduce these emissions. We investigate, on a life cycle basis, wood pellet firing and cofiring with coal in two coal generating stations (GS) in Ontario, Canada.
