Abstract
The sustainability of biofuels has to be judged based upon the net energy they contribute to society and the amount of greenhouse gas (GHG) they emit compared to their energy equivalent in fossil fuel. In addition, they also have to be judged by their efficient use of resources such as land and water as these are competed for in the production of food, fiber, and timber or for ecosystem services. This chapter explores these metrics by the life-cycle analysis (LCA) of bioenergy produced from annual and perennial feedstocks and includes GHG emission from land-use change. These land-use-change emissions will include the change in carbon stocks in standing vegetation and soils as well as trace gas emissions of CH4 due to water table changes and N2O emissions from the use of fertilizers.
