Abstract

Although the circular economy (CE) is recognised as a key climate mitigation strategy, its integration within global climate frameworks, such as those developed by the Intergovernmental Panel on Climate Change (IPCC) in its Assessment Reports, remains unclear. This study provides a systematic analysis of how the circular economy is framed in the climate-mitigation context of the IPCC Sixth Assessment Report using a mixed-methods approach that combines computational text analysis with qualitative content analysis through sentence-level manual coding. Eight Chapters relevant to the mitigation were examined and findings show that CE is most frequently framed as a supporting strategy (44.3%), followed by implicit (29.3%) and primary roles (26.4%), while being unevenly distributed across sectors, with the strongest representation in industry.
