Abstract

This chapter presents the main methodological aspects of Life Cycle Assessment (LCA) and discusses the key published studies regarding biojet fuels. In addition to the intrinsic performance of each biofuel pathway (productivity, cultivation practices, use of inputs, etc.), the different methodological considerations among the studies also explain the differences in the life cycle emissions. Almost all pathways presented better performance in terms of greenhouse gas (GHG) emissions than the conventional jet fuel (which produces between 88 and 106 g CO2eq/MJ), but the range of values for some ...
