Abstract
Circular economy (CE) strategies hold substantial potential for reducing product carbon footprints (CF), yet their effectiveness and specific impact pathways remain unclear. This study develops a quantitative framework for calculating and comparing the CF under various CE strategies, demonstrated with a case of lithium-ion batteries (LIBs). Results show CE strategies have varying impacts on material and other flows in a battery lifecycle and do not necessarily reduce CF. A combination of six CE strategies halves the CF of LIBs, suggesting additional efforts are required for deeper decarbonisation. This framework offers insights to guide effective CE actions and advance sustainable products.
