Abstract
A development of the top down method for accounting for all direct and indirect land use change emissions (LUCE) is presented, which reflects the relative rates of global crop expansion. It uses crop production and area data from FAOSTAT to derive expansion rates, reflecting global demand. Crops that drive land use change more, e.g. soy thus receive a heavier burden than other. It is thus more equitable than the original top down method. Alternative sources of values for LUCE and connected agricultural area are addressed. It still represents a method with relatively low computational and data demands.
