Highlights The links between transparency and sustainabilityare poorly understood. We present a typology of information for supply chain governance. The coverage of existing transparencyinitiatives is limited and biased in scope. We present ten ways in which transparency can improve sustainability governance.

Digital technology is regarded as providing a promising means of moving production and consumption towards the circular economy. However, it is still unclear which functions of digital technologies are most useful to improving circularity, and how these functions could be used to enhance different circular economy strategies. This paper aims to address this knowledge gap by conducting a systematic literature review. After examining 174 papers, creating 782 original codes and 259 secondround codes, the study identifies 13 critical functions of digital technologies which are most relevant to circular economy strategies. The paper then proposes a framework which reveals seven mechanisms of how these digital functions can enhance different circular economy strategies. The framework also reveals which combinations of the digital functions and circular economy strategies have already been studied extensively as well as where there may be gaps. This indicates which digital functions are more mature in terms of possible implementation for circular economy as well as what missing links there are in the empirical and theoretical research. The study advances the synergies between digital technologies and the circular economy paradigm through the lens of digital functions. The proposed framework and mechanisms build a theoretical foundation for future research, and we highlight five research areas for further studies. This study also provides a structured way for managers to explore the appropriate digital functions for their CE strategies, so as to identify required digital technologies and new value creation through digital functions.

Product–service systems (PSSs) have significant sustainability potential. However, limited knowledge is available on the choices to develop circular PSS solutions. The goal of this paper is to provide a circular innovation framework containing circular strategies to facilitate the decision-making in PSS circular innovation. A systematic literature review in combination with content analysis underpinned this research. The strategies were investigated in 45 PSS cases from the literature. A coding system was designed and employed to identify and organize the circular strategies and practices. The statistics techniques employed were frequency and co-occurrence analysis, which aimed to describe the synergies among strategies. The framework proposed contains twenty-one circular strategies. The practical perspective comprises the seventy-seven practices used for the operationalization of strategies. The framework can assist organizations in making strategic to tactical decisions when developing circular PSS solutions. The paper provides a panorama of the strategy applications among the PSS types. Finally, the research approach can be employed to continuously develop an understanding of the application of circular strategies in PSS and other fields.

A transition to the circular economy may be a solution to dissociate financial growth from negative environmental impacts. However, this transition can require an in-depth understanding of which enablers an organization requires. This research aims to identify the enablers of the circular economy presented in the literature and analyze them against the theories about resources, capabilities, and dynamic capabilities and against the ReSOLVE framework. Through a systematic literature review, this research identified thirteen enablers grouped in three different dimensions (management and people; structure, product, and process; and relationship with stakeholders). Some enablers can be considered as resources, capabilities, or dynamic capabilities and are capable of helping firms to reach a successful transition to the circularity. They may even be sources of competitive advantage in the context of circular economy, mainly the enablers of the dimension "structure, product, and process." The dimensions of enablers have direct and indirect links with the ReSOLVE framework action areas. Through the discussions of some real cases, it was possible to exemplify how some enablers lead companies to circularity. Besides that, this research posits seven research gaps for future studies.
