  Switchgrass Miscanthus Corn stover Corn
Minimum U.S. LUC GHG emissions −3.9 −12 −0.24 1.2
Maximum U.S. LUC GHG emissions 13 −3.8 −0.19 7.4
International LUC GHG emissions 6.7 1.7 −0.97 3.5
LUC GHG emissions range 2.7 to 19 −10 to −2.1 −1.21 4.7 to 11
Lifecycle GHG emissions rangeb 10 to 26 −8.5 to −0.20 0.97 to 1.0 62 to 68
  1. a Values presented represent range of results generated at all combinations of surrogate CENTURY (Table 4) and CCLUB modelling parameter settings discussed.
