Substantial potential exists to expand supplies of biomass for energy applications through more systematic collection of agricultural residues, more intensive cultivation of croplands, and reduced waste and losses in the food chain. This study aims to show how the potential can be calculated from public information sources, to put the potential in the context of global needs for liquid transport fuels, and to suggest some practical policy options for bringing part of the potential to market. It finds that if the theoretical potential is fully realized, enough liquid biofuel could be produced to displace the equivalent of all current global liquid fuel use for transport.
