Abstract: The report presents an independent estimate of the part of LUC emissions due to deforestation, starting from the 29% of historical deforestation area (and estimated emissions) caused by expansion of different crops. The deforestation area and emissions per tonne of extra crop are converted to emissions per MJ biofuel from that crop. The average global deforestation caused by increase in production of a crop or biofuel is estimated, making no geographical differentiation in where the extra demand occurs or where that would provoke deforestation. The source of historical deforestation data is a report published by DG ENV [EC 2013] which estimates which areas of forest were lost to different crops and to other land uses (grazing, logged forest, urban and others) between 1990 and 2008. It used historical deforestation data from FAO’s Forest Resource Assessment 2010, interpreted with other FAO data. The emissions are calculated only from deforestation and peat forest drainage, attributed to each MJ biofuel. This does not include emissions from the grassland area converted to cropland. This method gives an independent verification of the general magnitude of LUC area and emissions which should be expected from bottom-up models of LUC for scenarios, and the results indicate that historical LUC emissions were higher than those estimated by most economic models.
