摘要：This study estimates the greenhouse gas (GHG) emissions of a switchgrass supply system for a potential biorefinery producing 50 million gallons of biofuel annually in Tennessee. Under the condition of minimizing the cost of feedstock, the estimated annual GHG emissions of the switchgrass supply system are 256 g CO2e/m2.
