Sugar J.110, 1317, 527-545ANNEXUREDEFAULT VALUES USEDIt is expected that some of these default values will change as more accurate or realisticvalues are published. Further fine tuning may also be incorporated in future e.g. in allowingfor different emissions from different types of nitrogenous fertilizer. It may also benecessary to introduce country specific default values where they are seen to make amaterial difference to the calculations.Most of the default values are obtained from the EBAMM model (Farrell et al. 2006), oftenbased on the GREET model using data from Shapouri et al. (2004) and Graboski (2002), orfrom Macedo et al.
