生命周期评估从业人员经常面临缺少化学品生命周期清单数据集的问题，因为目前的数据库只涵盖商业使用的一小部分化学品。在这里，我们批判性地回顾了LCA从业者用来估计缺失的化学LCI数据的八种不同方法，包括过程模拟，工程过程计算，基于分子结构的模型，化学计量方法，使用代理和遗漏。每一种方法都从技术上进行了描述，从文献中的例子，优点和缺点的描述，并根据数据和专业知识的可用性的适用性的讨论。然后，使用苯乙烯及其下游产品丙烯腈-丁二烯-苯乙烯（ABS）的案例研究，对方法进行充分论证，并与报告的化学工业数据进行准确性比较。由此产生的LCI和生命周期影响评价（LCIA）值进行了比较和讨论，特别注意特定方法的排除…
A life cycle assessment (LCA) practitioner is often faced with the problem of missing chemical life cycle inventory (LCI) data sets, as current databases cover only a small fraction of chemicals used in commerce. Here, we critically review eight different methods used by LCA practitioners to estimate missing chemical LCI data, including process simulation, engineering process calculations, molecular structure-based models, stoichiometric approaches, use of proxies, and omission. Each method is technically described with examples from the literature, description of advantages and disadvantages, and discussion of suitability depending on availability of data and expertise. Methods are then fully demonstrated and compared for accuracy against reported chemical industry data using case studies of styrene and its downstream product, acrylonitrile-butadiene-styrene (ABS). Resulting LCI and life cycle impact assessment (LCIA) values are compared and discussed, with specific attention to method-specific exclusion...
