土地资源的利用对生物燃料生产的可持续性有很大影响。如果要对可持续性作出准确的评估，就必须对土地使用的直接和间接变化进行评估。越来越多的研究开发了估算生物燃料在全球、国家或区域层面的间接土地利用变化（ILUC）影响的方法，但评估ILUC仍然是一项具有挑战性的任务，估计值差异很大。在这项研究中，我们建议，社会动机，项目水平的方法可以提供强大的洞察力的条件影响土地利用变化动态。我们开发了一个名为ILUC项目评估工具（ILUC PAST）的项目描述性方法，用于ILUC项目级评估。它使用了从地方到全球的分层多工具分析，并结合了广泛的利益相关者参与。在撒丁岛（意大利）生产纤维素乙醇的一个现实世界的项目被用来评估工具和基准的结果对两个替代方案的项目级评估：“低间接影响生物燃料”的方法和“iLUC俱乐部”的方法。先进生物燃料的案例研究结果表明，ILUC的定量估计加上ILUC PAST提供的因果动态的深入理解，足以支持项目层面和地方决策。
The use of land resources has a strong influence on the sustainability of biofuel production. An assessment of both direct and indirect changes in land use is necessary if an accurate assessment of sustainability is to be made. An increasing number of studies have developed approaches to estimate the Indirect Land Use Change (ILUC) impacts of biofuels at global, national or regional level, but assessing ILUC remains a challenging task and estimates vary widely. In this study, we suggest that a socially motivated, project level approach can provide robust insight into the conditions affecting land use change dynamics. We developed a causal-descriptive approach named ILUC Project ASsessment Tool (ILUC PAST) for project level assessment of ILUC. It uses a tiered multitool analysis-from local to global-combined with extensive stakeholder engagement. A real-world project for the production of cellulosic ethanol in Sardinia (Italy) was used to evaluate the tool and benchmark the results against two alternatives for project level assessment: the 'Low Indirect Impact Biofuel' methodology and the 'iLUC Club' method. The results of the case study of advanced biofuels suggest that the quantitative estimates of ILUC combined with the in-depth understanding of the cause-and-effect dynamics provided by ILUC PAST are sufficiently credible, salient and legitimate to support project level and local decision-making.
