The circular economy principles are believed to contribute to waste reduction, pollution and climate change prevention, conservation of resources and security of their supply, and economic resilience. Therefore, it is extremely important not only to implement the principles of the circular economy, but also to properly assess their impact, so that stakeholders can make reasonable decisions and develop effective strategies to promote the green transition. Nevertheless, despite a wealth of literature to discuss the circular economy indicators, a comprehensive assessment method has not yet been developed.
The research problem is formulated as a question: what indicators can be used to assess the level of the circular economy in national economies? The major purpose of the research is to empirically assess the level of the circular economy in the EU Member States. The research methods include literature analysis, systematisation and summarisation; secondary data analysis; weight estimation methods: the Entropy and expert evaluation; mutiple-criteria decision analysis: the PROMETHEE, SAW and TOPSIS methods.
