Assessment of Australia biomass for producing bioelectricity and biofuel and reducing greenhouse gas emissions

The data tables (inputs and results) supported "a quantitative assessment of the prospects for current and future biomass feedstocks for bioenergy in Australia, and associated estimates of the greenhouse gas (GHG) mitigation resulting from their use for produc- tion of biofuels or bioelectricity." (from the Abstract of GCB Bioenergy, 4(2):148–175.
