A panacea to unsustainable consumption? A review of resource caps
Abstract
Abstract Non-technical summary Many of the most pressing issues of today, such as climate change, habitat destruction, and conflict, are linked to our growing economies and the increasing amount of natural resources needed to maintain them. Current resource management policies focus on using resources more efficiently while maintaining economic growth. However, these policies have been insufficient and alternatives are needed. Resource caps are one such alternative which would directly limit resource consumption and extraction. This first review on the topic covers existing research on resource caps, the practical issues of implementation, and suggests a way forward for future policy and research. Technical summary Increasingly unsustainable rates of resource consumption and extraction have led to a growing discussion among researchers and environmental advocates on introducing caps on resource use. Research suggests that a reliance on efficiency-based approaches and a focus on decoupling are not sufficient to reduce ecosystem pressures, and instead alternatives such as resource caps may be needed. This article therefore provides the first comprehensive review of research on resource caps, linking them to major social science debates on resource scarcity, social metabolism, decoupling, and degrowth. Resource caps have been increasingly proposed in contemporary degrowth research, but this review found that resource caps are compatible with the agendas of those who endorse ‘green growth’ or ‘ecomodernist’ positions. Although resource caps are commonly proposed at a global level, it was found that enacting national or regional level caps is more viable, and that such caps should be developed through post-normal science and with democratic governance. However, current research does not show how resource caps can be implemented in practice, despite there being a detailed discussion on the political and social factors surrounding implementation. Future research will need to consider how, and even if, caps can function, and in what situations they are effective. Social media summary Capping consumption and extraction of natural resources is an alternative to current efficiency-based resource policies.
