第2009/28/EC号指令确立了总体目标，即到2020年，每个欧洲成员国的可再生能源应占能源消费的20%。此外，该指令为运输部门的生物燃料设定了10%的强制性最低目标。生物燃料可能是矿物柴油的重要替代品。我们提议在锡耶纳省(托斯卡纳省)建立一条从向日葵中提取生物柴油的试点生产线，以研究在运输部门减少化石燃料消耗的可能性。这项研究可能为减少运输部门对石油的依赖提供了机会。环境影响指标由物质流核算、体现能值分析和能值核算提供。结果表明，农业阶段是生产线上的关键环节。对生物柴油生产线和矿物柴油生产的比较生命周期评估分析表明，生物燃料生产具有环境优势，但需要更高的土地需求。因此，生物柴油可能不是大规模的最佳解决方案，但可能是化石燃料的良好替代品。这将取决于在有限区域内进行的整个生产周期。为了满足当地农场和小企业的需求，这是必要的。
The Directive 2009/28/EC established the overall target that 20% of energy consumption should be represented by renewable energy sources by 2020 in each European member state. Furthermore, the Directive sets a mandatory 10% minimum target for biofuels in the transport sector. Biofuels are potentially an important alternative to mineral diesel. We propose a pilot production line of biodiesel from sunflower on local scale in the Province of Siena (Tuscany) to research a possible reduction of fossil fuel consumption in the transport sector. This study might represent an opportunity to reduce petroleum dependence in the transport sector. Environmental Impact Indicators were provided by Material Flow Accounting, Embodied Energy Analysis and Emergy Accounting. Results showed that agricultural phase is the critical step in the production line. A comparative Life Cycle Assessment analysis for the biodiesel production line with mineral diesel production showed environmental advantages of the biofuel production, however requiring a higher land demand. Therefore, biodiesel may not the optimal solution on large scale but might be a good alternative to fossil fuel. This would depend upon the entire production cycle taking place in a limited area. This is necessary in order to fulfill the needs of local farms and small enterprises.
