The EU Commission Ecolabel and the Product and Environmental Footprint (PEF) aim at promoting the development and consumption of greener products. The product aquatic toxicity score from these 2 methods may lead in some circumstances to opposite conclusions. Although this could be interpreted as an inconsistency, the score should not be compared to each other but used in a complementary way. In short, CDV provided a "full" product formula aquatic toxicity score, even if some chemicals may never reach or persist in freshwater ecosystems. The USEtox® score, by integrating fate and exposure, focuses on the potential toxicity of persistent-water-soluble chemicals at steady state. Since no risk or safety assessment can be conducted with USEtox® nor with the CDV, both are a hazard-based scoring system. This short communication clarifies the difference between approaches underpinning the toxicity scores used in Ecolabel and PEF, providing guidance on how to interpret the results.
欧盟委员会生态标签和产品及环境足迹（PEF）旨在促进绿色产品的开发和消费。这两种方法的产品水生毒性评分在某些情况下可能会得出相反的结论。尽管这可能被解释为不一致，但不应将评分相互比较，而应互补使用。简而言之，CDV 提供了“完整”的产品配方水生毒性评分，即使某些化学物质可能永远不会到达或在淡水生态系统中持续存在。USEtox®评分通过整合归宿和暴露，侧重于在稳定状态下对持久性水溶性化学物质的潜在毒性。由于无法对 USEtox®或 CDV 进行风险或安全评估，因此两者都是基于危害的评分系统。本简讯阐明了生态标签和 PEF 中使用的毒性评分所依据的方法之间的区别，为如何解释结果提供了指导。
