在保证税收减免的同时，欧洲各国政府打算到2010年将生物燃料在欧盟燃料消费总量中的份额提高到5.75%。欧盟对这一目标的财政支持通常是由于预期的积极环境影响，特别是减缓气候变化，以及农业部门的有利就业影响。本文对支持以油菜籽为原料的生物柴油作为化石柴油替代品的环境和经济影响进行了研究。根据最近的实证研究调查，我们发现，这一环境战略的能源和温室气体平衡明显是积极的，但其总体环境平衡目前还远未明确为积极的。最重要的是，生物柴油不是一种具有成本效益的减排战略。因此，为了减少温室气体，我们建议采用以可再生技术和传统技术为基础的更有效的替代办法。
Guaranteeing tax reductions and exemptions, the European governments intend to increase the share of biofuels in total EU fuel consumption to 5.75% by 2010. The financial support of this EU objective is frequently justified by expected positive environmental impacts, most notably the mitigation of climate change, and by favorable employment effects in the agricultural sector. This paper investigates the environmental and economic implications of the support of rapeseed-based biodiesel as a substitute for fossil diesel.Based on a survey of recent empirical studies, we find that the energy and greenhouse gas balances of this environmental strategy are clearly positive.Yet, its overall environmental balance is currently far from being unequivocally positive. Most importantly, biodiesel is not a cost-efficient emission abatement strategy. Thus, for the abatement of greenhouse gases,we recommend more efficient alternatives based on both renewable and conventional technologies.
