随着能源消耗和温室气体（GHG）排放的增加，传统化石燃料逐渐枯竭，导致人们转向可再生和可持续能源。木质纤维素生物质数量巨大，为生物乙醇生产提供了巨大的潜力。然而，为了确定最佳的生物燃料策略，有必要考虑从摇篮到坟墓的环境影响。生命周期评估 (LCA) 技术可以对区域和全球范围内的材料和能量通量进行详细分析。这包括生产过程的间接投入以及相关的废物和排放，以及产品未来的下游命运。同时，如果使用不当，LCA 可能会导致行业和/或政策制定者采取不正确和不恰当的行动。本文旨在列出量化与木质纤维素生物乙醇生产的整个生命周期相关的资源使用和环境排放的关键问题。
Progressive depletion of conventional fossil fuels with increasing energy consumption and greenhouse gas (GHG) emissions have led to a move towards renewable and sustainable energy sources. Lignocellulosic biomass is available in massive quantities and provides enormous potential for bioethanol production. However, to ascertain optimal biofuel strategies, it is necessary to take into account environmental impacts from cradle to grave. Life cycle assessment (LCA) techniques allow detailed analysis of material and energy fluxes on regional and global scales. This includes indirect inputs to the production process and associated wastes and emissions, and the downstream fate of products in the future. At the same time if not used properly, LCA can lead to incorrect and inappropriate actions on the part of industry and/or policy makers. This paper aims to list key issues for quantifying the use of resources and releases to the environment associated with the entire life cycle of lignocellulosic bioethanol production.
