| Use of biofuels diminishes fossil fuel combustion, thereby also reducing net greenhouse gas emissions. However, subsidies are needed to make agricultural biofuel production economically feasible. To explore the economic potential of biofuels in a greenhouse gas mitigation market, we incorporate data on production and biofuel processing for the designated energy cropsswitchgrass, hybrid poplar, and willowin a U.S. Agricultural Sector Model, along with data on traditional crop-livestock production and processing, and afforestation of cropland. Net emission coefficients on all included agricultural practices are estimated through crop growth simulation models or are taken from the literature. We simulate potential emission mitigation policies or markets... |
