Spatial variability in yields and greenhouse gas emissions from soils has been identified as a key source of variability in life cycle assessments (LCAs) of agricultural products such as cellulosic ethanol. This study aims to conduct an LCA of cellulosic ethanol production from switchgrass in a way that captures this spatial variability and tests results for sensitivity to using spatially

assessments (LCA), Farrell and colleagues (10) found that current corn ethanol production yields an NEV of ap-proximately 5 MJ L-1 and a GHG intensity of -18% (uncertainty range: -36% to +29%) compared with that of conventional gasoline. Similarly, ethanol derived from both switchgrass and corn stover has been shown to have higher
