Summary
Circularity metrics are useful for empirically assessing the effects of a circular economy in terms of profitability, job creation, and environmental impacts. At present, however, there is no standardized method for measuring the circularity of products. We start by reviewing existing product‐level metrics in terms of validity and reliability, taking note of theoretically justified principles for aggregating different types of material flows and cycles into a single value. We then argue that the economic value of product parts may constitute a useful basis for such aggregation; describe a set of principles for using economic value as a basis for measuring product circularity; and outline a metric that utilizes this approach. Our recommendation is to use the ratio of recirculated economic value to total product value as a circularity metric, using value chain costs as an estimator. In order to protect value chain actors’ sensitive financial data and facilitate neutrality regarding outsourcing or insourcing, we suggest a means to calculate product‐level circularity based on sequential approximations of adding one product part and activity at a time. We conclude by suggesting potential avenues for further research, including ways in which the proposed metric can be used in wider assessments of the circular economy, and ways in which it may be further refined.
This paper examines how institutional factors influence developments in the field of Mobility as a Service (MaaS). We draw upon neo-institutional theory in order to describe drivers and barriers of MaaS developments in Sweden and Finland. By analyzing similarities and differences across the cases, we identify a set of general implications for MaaS policymakers and practitioners. Developments in Finland demonstrate the importance of top-level support, of inter-organizational collaboration and of trust among key stakeholders. The Swedish case reiterates the need for inter-sectorial collaboration, particularly with regard to creating the right conditions for commercialization, and to involving stakeholders on both strategic and operational levels of the transport sector in developing the vision for MaaS. Lastly, we also assess the utility of the applied theoretical framework, and comment on the necessity of recognizing that both practice-based and structural changes are needed in order to facilitate institutional change.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
