An urgent call for circular economy advocates to acknowledge its limitations in conserving biodiversity.

This discussion paper explores the relationship between biodiversity and the circular economy and the potential implications of this relationship. The circular economy has emerged as an alternative model to a traditional linear economy. It aims to tackle the resource exploitation that accompanies a linear economy and decouple economic growth from reliance on primary resources. In the face of global environmental degradation and an urgent need for change, the concept has become popular around the world and has led to the release of national policies and strategies on the circular economy. Problematically, while the basic concept is clear, it is ambiguous in how it will achieve some of its objectives, and it fails to address some key issues. In light of the accelerating rate of change, precipitous biodiversity decline is one such key issue. Through a content analysis of relevant circular economy publications, authors demonstrate that biodiversity protection is rarely mentioned in theory and policy. While the circular economy holds many benefits for society, its evasion of scrutiny has prevented it from manifesting in a comprehensive solution to environmental issues. The circular economy advocates for biomimicry, ecosystem service valuation, bioeconomy, and renewable energy. Each of these, however, has its own set of conflicts with biodiversity protection. Given the imminent need to protect biodiversity, the authors call for further research on the interaction between biodiversity and the circular economy, and for circular economy advocates to explicitly acknowledge the concept's limitations, thereby revealing the need for intersectional and complementary policies which aim to protect biodiversity.
