一旦批准了《京都议定书》，西班牙就面临着减少温室气体排放的巨大挑战。建议采取的措施之一是在市场上引入生物燃料，既用于运输部门，也用于供热。本文比较了生产生物燃料对环境的影响，生物燃料的来源是从向日葵、油菜籽和大豆中获得的油。每项生产的环境影响均采用生命周期分析（LCA）方法进行。影响较大的类别是土地使用，化石燃料，致癌物，无机呼吸和气候变化。其原因主要是由于种子生产过程。我们还发现了对种子的干燥和制备过程以及粗大豆油提取过程的显著影响。此外，生命周期评估显示，油菜籽和向日葵的生产对气候变化有积极的贡献。
Once ratified the Kyoto protocol, Spain arises the great challenge of reducing the emissions of greenhouse gases. Among the measures proposed is the introduction of biofuels in the market, both for the transport sector and for the production of heat. This paper compares the environmental impact from the production of biofuels whose origin is the oil obtained from sunflower, rapeseed and soybeans. The environmental impact of each production is performed by applying the methodology of life cycle analysis (LCA). The categories where you get a greater impact are land use, fossil fuels, carcinogens, inorganic respiratory and climate change. The cause is mainly due to the processes of seed production. We have also found a significant impact on the drying and preparation processes of the seed as well as the crude soybean oil extracting process. Moreover as the LCA shows production of rapeseed and sunflower has a positive contribution to climate change.
