Circular Economy (CE) is a growing trend, especially in the European Union, that promotes the responsible and cyclical use of resources, contributing, whereas possible, to sustainable development. CE is an umbrella concept incorporating different meanings. Despite the complex concept, CE is implemented through defined action plans supported by specific indicators. To understand what specific indicators used in CE are aimed to measure exactly, some researchers (universities of Ghent and Leuven and the Joint Research Centre in Ispra) proposed a classification framework to categorize indicators through reasoning on what (CE strategies), and how (measurement scope), indicators measure. Here we report an abstract of the article. Despite different types, CE strategies can be grouped according to their attempt to preserve functions, products, components, materials, or embodied energy; additionally, indicators can be applied also to the linear economy as a reference scenario. The measurement scope shows how indicators account for technological cycles with or without a Life Cycle Thinking (LCT) approach; or their effects on environmental, social, or economic dimensions.
