The need for incorporating sustainability principles as a design goal rather than a constraint has prompted major changes in chemical process design and engineering in recent decades. In this regard, sustainability assessment via economic, environmental, and social dimensions, a triad referred to as the triple bottom line (TBL), is becoming not only an accounting tool but also a means to re-evaluate the design of a given process or product. Nevertheless, the inherent complexity of sustainability assessment by considering the TBL gives rise to a variety of challenges that should be addressed at each stage of process design. At the outset, the design problem is open to interpretation and information is scarce; thus, the metrics for the sustainability dimensions cannot be easily implemented. In subsequent design stages, when detailed information is available, the potential for sustainability enhancement is constrained by the preliminary decisions made on the process design. This indicates that distinct sustainability metrics should be deployed at the various stages of the design task to capture and quantify the impacts derived from a process, or product, thereby facilitating their reduction. Thus, this work aims at summarizing recent developments on sustainability metrics and classifying them according to the stages of the process design at which they could be utilized.

最近几十年来，将可持续性原则作为设计目标而非约束的需求促使化学过程设计和工程发生了重大变化。在这方面，通过经济，环境和社会层面的可持续性评估（一个被称为三重底线（TBL）的三元组）不仅正在成为一种核算工具，而且正在成为一种重新评估给定流程或流程设计的手段。产品。然而，通过考虑TBL的可持续性评估的内在复杂性带来了在过程设计的每个阶段都应解决的各种挑战。一开始，设计问题易于解释，信息匮乏。因此，可持续性维度的度量标准不容易实现。在随后的设计阶段，当可以获得详细信息时，可持续性增强的潜力将受到对流程设计的初步决策的限制。这表明应在设计任务的各个阶段部署不同的可持续性度量标准，以捕获和量化来自过程或产品的影响，从而促进其减少。因此，这项工作旨在总结可持续性指标的最新进展，并根据可利用这些指标的流程设计阶段对其进行分类。或产品，从而促进其减少。因此，这项工作旨在总结可持续性指标的最新进展，并根据可利用这些指标的流程设计阶段对其进行分类。或产品，从而促进其减少。因此，这项工作旨在总结可持续性指标的最新进展，并根据可利用这些指标的流程设计阶段对其进行分类。
