本章全面概述了生命周期评估目前的差距和挑战，分为清单、影响评估、一般和不断发展的方面。共确定了34项差距和挑战。这些挑战包括“分配”、“不确定性”或“生物多样性”，以及“乱扔垃圾”、“动物福利”或“积极影响”等问题，这些问题在现有的LCA文献中并不常见。每一个这些差距都描述了一个高层次的概述的主题及其相关性的LCA，和最先进的文献和潜在的解决方案，如果有的话，presented.The这样一个概述的动机是双重的：第一，强大的，可持续的和可信的使用LCA应避免过度解释LCA的结果没有适当考虑其差距和局限性。其次，这些差距和挑战代表了科学界对生命周期评估的研究需求，并有望激发方法开发的进一步进展。
This chapter provides a comprehensive overview of current gaps of and challenges for LCA structured into inventory, impact assessment, generic and evolving aspects. A total of 34 gaps and challenges were identified. These include challenges like 'allocation', 'uncertainty' or 'biodiversity', as well as issues like 'littering', 'animal well-being' or 'positive impacts' which are not covered as often in the existing LCA literature. Each of these gaps is described by a high-level overview of the topic and its relevance to LCA, and the state of the art in terms of literature and potential solutions, if any, is presented.The motivation for such an overview is two-fold: First, robust, sustainable and credible use of LCA should avoid the over-interpretation of LCA results without proper consideration of its gaps and limitations. Second, these gaps and challenges represent research needs for the scientific LCA community and hopefully inspire further progress in method development.
