Green chemistry aims to use renewable materials, reduce waste, and avoid toxic substances and is defined by 12 principles of green chemistry. Green metrics (GM) are measurable figures that assess adherence to the 12 principles of green chemistry. GM are designed to be user‐friendly and can be applied without detailed process knowledge. Life cycle assessment (LCA) is another approach used to estimate the environmental impacts of products or processes throughout their life cycle. This paper compares LCA and GM, exploring their suitability for assessing the greenness of chemical products and processes. This includes the discussion of strengths and weaknesses, limitations, application areas, benefits of combining both approaches, and how to handle conflicting results.

化学产品和工艺的评估：绿色指标和生命周期评估 - 比较

绿色化学旨在使用可再生材料、减少浪费并避免有毒物质，并由绿色化学的 12 条原则定义。绿色指标 (GM) 是可衡量的数字，用于评估对绿色化学 12 条原则的遵守情况。 GM 设计为用户友好型，无需详细的工艺知识即可应用。生命周期评估 (LCA) 是用于评估产品或流程在其整个生命周期中对环境影响的另一种方法。本文比较了 LCA 和 GM，探讨它们评估化学产品和工艺的绿色度的适用性。这包括讨论优点和缺点、局限性、应用领域、结合两种方法的好处以及如何处理相互冲突的结果。
