Abstract:
The paper presents the quantification of GHG emissions from biofuel production in Spain from raw materials cultivation up to biofuel final distribution. Raw materials considered are wheat, barley and sorghum for bioethanol production and rapeseed, sunflower and cardoon for biodiesel production. Cultivation stages are quantified taking into account the regional differences in yields and farming inputs in the Spanish areas classified as level 2 in the nomenclature of territorial units for statistics (“NUTS2”). Seed transport distances to the processing plants as well as the final distribution of the fuels are calculated using a GIS approach. Transformation processes considered are those in place in the Spanish biofuel facilities. The methodology used follows the methods described in the Annex V of the Directive 2009/28/CE on the Promotion of the Use of Energy from Renewable Sources. Results show the regional variations of cultivation stage GHG emissions and how they compare with the default values set in the Directive. GHG emission results of the different biofuel chains are also shown disaggregated into the different stages and for each of the NUTS2 regions considered. Overall GHG savings obtained compared with the use of a reference fossil fuel are also shown.
