Cultural heritage (CH) is considered a key element of cities and regions’ identity anduniqueness, contributing to people's wellbeing and health, as well as jobs creation, environmentalregeneration and place attractiveness. The adaptive reuse of abandoned and underused CH can be asustainable strategy for heritage conservation, stimulating local development processes. However,heritage conservation needs large investments, while the resources available are scarce, and invest-ment projects are subject to high uncertainties. Therefore, a careful assessment of impacts is neededto orient and direct CH adaptive reuse projects towards sustainability. Recent studies approach theadaptive reuse of abandoned buildings and sites as an effective circular economy strategy, potentiallycontributing to climate objectives through environmental regeneration and the reduction of naturalresources consumption. However, evaluation tools to assess the impacts and orient adaptive reuseinterventions in the perspective of circularity are lacking. Through the analysis of 76 literature sourceson CH impacts, this article explores how indicators are currently used in CH research and practice asimpact assessment tools. More than 3500 indicators were retrieved and classified. Finally, this articleproposes a comprehensive evaluation framework to assess the impacts of cultural heritage adaptivereuse in the perspective of the circular economy. The results show that, while some indicators areavailable, many circularity aspects are not considered in the current studies on CH impacts.

Relying on the hybrid organization literature and the circular economy literature, our study aims at theorizing how hybrid organizations adopt circular economy business models to contribute to sustainable development. Through six in-depth interviews with social entrepreneurs located in different regions of Italy and operating in different industries, we theorize that four aspects are unique to hybrid organizing that adopt a circular economy business model. We find that hybrid organizations foster sustainable development thanks to their ability to develop and maintain relationships with the surrounding organizational realities. Additionally, we find that hybrid organizations contribute to sustainable development thanks to their motivation to guard and watch over the natural environment and human beings. In addition, we find that hybrid organizations foster sustainability by educating, spreading knowledge, and ennobling the human spirit. We therefore present a conceptual model that shows how hybrid organizations that adopt circular economy models contribute to sustainable development. In sum, our findings expand on previous literature, add new knowledge, and integrate fields of research that usually develop in silos.

Nowadays, the challenge of sustainability is increasingly played out in cities, which represent the favoured field of action to implement strategies and actions for supporting the transition towards a more human and ecological development paradigm. The problems caused by the current economic model (linear model) are even more stressed today due to the effects produced by the COVID-19 pandemic. The tourism sector (one of the world’s major economic sectors and, thus, one of the main players in the development dynamics) is one of the economic sectors that has been the most negatively impacted by the pandemic. In this study, Human Circular Tourism (HCT) is proposed as a strategy to move towards a more sustainable future and, thus, reduce the negative impacts produced by the tourism sector. In particular, the objective of this paper is to understand the awareness of travellers (one of the categories of actors involved in the tourism experience) regarding sustainable and circular tourism in order to support local governments in the elaboration and implementation of strategies and actions towards more sustainable and circular tourism. To this end, a survey was conducted. In particular, a questionnaire was developed and submitted to a sample of tourists from all over the world to understand their behaviours and perceptions in their tourist experiences. From a critical analysis of the results, it emerges that there is a growing awareness of issues related to the concept of sustainability, especially in relation to the major issues of climate change and people’s health. This perception has certainly been influenced by the health emergency from COVID-19, but the sample of interviewees reveals that much still needs to be invested in increasing their awareness of the complexity of the factors involved in more sustainable, circular, and human-centred tourism. Therefore, starting from this, possible future prospects for the tourism sector from the circular economy perspective are here identified.
