New European Environment Agency briefing reviews over 130 studies and assesses potential emissions reductions from circular economy approaches. A European Environment Agency (EEA) briefing published this week has assessed the climate mitigation potential of circular economy strategies, drawing on a review of 131 recent studies and modelling results. The analysis suggests that circular approaches – such as waste reduction, reuse, recycling, material substitution and changes in consumption patterns – could significantly cut greenhouse-gas (GHG) emissions, though estimates vary widely across sectors and measures. According to the briefing, the average emission reductions estimated across the reviewed literature amount to about
