Supplementary material: Detailed temporal analysis of CE–SDG mapping dynamics

This supplementary material provides detailed temporal data on the mapping of 2,700 circular economy (CE) indicators to the 17 Sustainable Development Goals (SDGs), covering the period 2011–2024. It includes year-by-year distributions for each SDG, identification of emergence years based on a defined threshold method, and supporting data for temporal clustering and pattern analysis. These results offer additional insights into the evolution of CE–SDG alignment and highlight emerging trends, gaps, and shifts in thematic emphasis over time.
