Abstract: Biofuels could reduce reliance on fossil oil, while helping to reduce greenhouse gas emissions and promoting rural development. This study assessed the viability of using local biodiesel production from sunflower in Tuscany (Italy) to meet inland demand for diesel fuel in compliance with the European Directives. A crop growth model, GIS and geostatistics were used to identify suitable areas for biodiesel production, considering potential sunflower yields alongside essential sustainability criteria: energy efficiency and greenhouse gas (GHG) savings throughout the supply chain. Simulation results indicate that biodiesel potential, estimated at 95,000 t/year, corresponds to 104,400 tCO2 eq/year of GHG saved and to 26,500 TOE/year of fossil energy saved. Two scenarios of biodiesel requirement, derived from EU targets, were evaluated. The results of the evaluation indicated that the 2010 target of replacing 5.75% of transportation diesel fuel can be met, while the 2020 target (reaching a 10% of replacement) cannot be met, since local biodiesel production could replace only 4.78% of diesel fuel requirement. A third scenario considered replacing diesel fuel currently used in the agricultural sector. Results showed that the fuel requirement of this sector cannot be fulfilled since biodiesel could cover only approximately 36% of the expected demand.
