Greenhouse Gas Emission Offsets of Forest Residues for Bioenergy in Queensland, Australia

Harnessing sustainably sourced forest biomass for renewable energy is well-established in some parts of the developed world. Forest-based bioenergy has the potential to offset carbon dioxide emissions from fossil fuels, thereby playing a role in climate change mitigation. Despite having an establish...
