摘要

To ensure that environmental impacts do not exceed the planet’s carrying capacity (CC), there has been growing interest in the development of ecodesign methodologies. These methods aim to support decision-making in human activities, with a particular focus on the Absolute Environmental Sustainability Assessment (AESA) methods. However, no consensus has yet been reached on the most suitable AESA method to support ecodesign. The aim of this study was to critically analyze the advantages and limitations of the main AESA methods, as well as to identify their key challenges and future applications with a focus on ecodesign. A systematic literature review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol to identify relevant studies from Scopus, Web of Science, and ScienceDirect databases. The results indicate that AESA methods can be classified into three groups: approaches based on planetary boundaries (PB-based methods, 51% of the reviewed studies), reference normalization factors (LCIA-based methods, 21%), and ecosystem services (ES-AESA, 16%), with CC environmental values grounded in the Safe Operating Space (SOS) concept. Among economic sectors, the application of AESA was most prominent in chemicals (28%) and food and agriculture (22%). Regarding AESA operationalization, life cycle–based methods tend to be more accessible for practical application, whereas PB-based methods are more complex but offer the advantage of translating results directly into planetary boundary metrics. The implications of this research highlight opportunities to support emerging technology assessment practices for designers and to integrate SOS considerations into the new product development process.
