摘要

循环经济（CE）战略在减少产品碳足迹（CF）方面具有巨大潜力，但其有效性和具体影响途径尚不清楚。本研究开发了一个定量框架，用于计算和比较各种CE策略下的CF，并以锂离子电池（lib）为例进行了演示。结果表明，CE策略对电池生命周期中的材料和其他流动有不同的影响，并不一定会降低CF。六种CE策略的组合使lib的CF减半，这表明需要进一步努力实现更深层次的脱碳。该框架为指导有效的CE行动和推进可持续产品提供了见解。

Impacts of circular economy strategies on product carbon footprint: A lithium-ion battery case

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.
