The Circular Economy (CE) is gaining increasing attention among businesses, policymakers and academia, and across research disciplines. While the concept’s strong diffusion may be considered its main strength, it has also contributed to the emergence of many different understandings and definitions, which may hinder or slow down its success. Specifically, despite growing attention, the role of the consumption side in the CE remains a largely under-researched topic. In the present review, we first search the literature by means of snowball mapping and a systematic key-word strategy, and then critically analyze the identified sources in order to elucidate the fundamental elements that should characterize consumption in a CE. We extract two pillars, directly from definition, that should be at the nucleus of future research on consumption in the CE: (1) the hierarchical nature of circular strategies, with “reduce” being preferred to all other strategies; and (2) the inadequacy of defining the CE only through its loops or strategies without considering its goal of attaining sustainable development. Moreover, the discussion is placed within the extant consumer research streams deemed relevant, in order to bridge these with the context of the CE. We highlight limitations of said research streams regarding their typical focus on the quality (and not the quantity) of consumption, the lack of heterogeneity in the theories and data collection methods employed, and the non-impact-based instruments typically used to measure consumption behaviors. We show how these limitations have contributed to the emergence of the intention–behavior gap, a phenomenon extant studies identify as key to overcome for encouraging sustainable consumption practices. In particular, we focus the analysis on the intention–behavior gap in order to: (1) establish the state-of-the-art; and (2) uncover avenues for future research addressing extant limitations.

Whilst the literature shows a clear relation between institutional pressures (normative, coercive, mimetic) on the adoption of Resilient and Green Freight Transportation (RGFT) practices on the one hand, and economic, operational and environmental performance on the other, very few studies have considered the role of social performance (both society and employee-wise) in this equation. Social performance is currently under investigation as a potential success indicator in RGFT practice implementation. However, well-established models that include this social indicator still lack in the field. To this end, this research builds upon an institutional theory-based model which includes social performance as one of the decision-making factors in the industry. A sample of 107 freight transporters from South East Europe (SEE) provides the data to test several structural relations through path analysis. Results show that the three aforementioned institutional pressures positively impact on RGFT practice implementation. However, the relation is positive for all three pressures only when successful RGFT practice implementation has a moderating effect. Similarly, RGFT practice implementation positively impacts on social performance, through which as moderator, it also yields environmental and economic performance. Lastly, the results show that social performance positively impacts on economic and environmental performance. Overall, this study contributes to institutional theory and green supply chain management by demonstrating the need for including social performance as a success indicator in RGFT practice implementation. Ultimately, this study provides insights for industries and policymakers from SEE and comparable regions.

The transition towards the circular economy (CE) entails transformative and system-wide changes, implying involvement, alignment, and cooperation between all stakeholders at all levels. However, debate continues around how best to achieve this. Additionally, little attention has been paid to developing models for identifying and mobilising all relevant stakeholders to implement CE policies at the regional level. This study sought to remedy these issues by analysing the relevant academic literature and policy documents and making the first attempt to adjust existing models—not only for the purpose of stakeholder mapping, but also for the proposition of a living constellation of stakeholders who should be considered when designing the transition towards a CE in a regional scenario. The CE-centric quintuple-helix model developed and proposed here promotes the emergence and deployment of trilateral networks, hybrid organisations, and development/co-operation platforms. This model adopts a balanced, participatory approach that requires a new constellation of stakeholders. Its foundations are built on the traditional industry–government–academia nexus and enlarged by the inclusion of the civil society sphere and the environmental subsystem. The environment is represented as the nucleus of the model, inspiring and triggering actions by the remaining four subsystems. The model is then implemented into two European regions with CE initiatives (Spain and Greece) to demonstrate its practical application.
