生物质能源的生产和使用对环境既有积极的影响，也有消极的影响。在做出有关能源作物的政治选择之前，应明确能源作物对环境的影响。对政策制定的一个重要帮助是评估能源作物环境可持续性的系统方法。到目前为止，大多数关于能源作物环境方面的研究主要涉及作物的能源生产以及二氧化碳减排可能产生的后果。荷兰农业与环境中心（CLM）开发了一种系统方法来评估生物质作物的生态和社会经济可持续性。该方法最好被描述为过程链的多标准分析，并且与生命周期评估 (LCA) 密切相关。我们方法的特点是使用：CLM 已应用该方法来评估四个欧洲地区十种潜在有趣的能源作物的可持续性。研究结果用于概述欧洲中长期土地可用性大规模生物质作物生产的前景。对于所考虑的作物，净能源预算范围从每公顷油菜籽 85 GJ 净避免化石能源到用于气化发电的青贮玉米每公顷 248 GJ 净避免化石能源。该工具的方法及其结果在 CLM 于 1996 年组织的“生物质生产的环境问题和欧洲能源供应路线”(AIR3-94-2455) 协调行动中进行了讨论。研究的主要结论：
The production and use of biomass for energy has both positive and negative impacts on the environment. The environmental impacts of energy crops should be clarified before political choices concerning energy crops are made. An important aid to policy-making would be a systematic methodology to assess the environmental sustainability of energy crops. So far, most studies on the environmental aspects of energy crops deal mainly with the energy production of the crops and the possible consequences for CO2mitigation. The Dutch Centre for Agriculture and Environment (CLM) has developed a systematic methodology to assess the ecological and socio-economic sustainability of biomass crops. The method is best described as a multicriteria analysis of process chains and is very much related to Life Cycle Assessment (LCA). Characteristics of our methodology are the use of: CLM has applied the method to assess the sustainability of ten potentially interesting energy crops in four European regions. The results are used to outline the perspectives for large scale production of biomass crops with regard to the medium and long term land availability in Europe. For the crops considered, net energy budget ranges from 85 GJ net avoided fossil energy per ha for rape seed for fuel to 248 GJ net avoided fossil energy per ha for silage maize for electricity from gasification. The methodology of the tool and its results were discussed at the concerted action “Environmental aspects of biomass production and routes for European energy supply” (AIR3-94-2455), organised by CLM in 1996. Major conclusions of the research:
