Approaches to account for land use change-related GHG emissions (LUCE), differing on the basis of the spatial allocation of the emis-sions, were compared in this study, and the justification of their application was evaluated based on generally accepted criteria from ISO 14040, PAS 2050 and IPCC guidelines. In general, most methods technically fulfilled those criteria, with exception of the "Worst case" or marginal approach which resulted in multiple counting of global emissions. The selection amongst the acceptable methods still remains rather subjective. The conclusions of agricultural LCA studies, related for example to the GHG emissions from livestock feed, are strong-ly dependent on the selected method, and for this reason a universally accepted single method is needed. One solution might be an appli-cation of a modified "Top down" method, which takes into account emissions from indirect LUC and the actual drivers affecting them.
