As underlined by OECD and United Nations, as cities are growing in size, they will face challenges in becoming climate neutral, reducing their environmental footprint, and meeting the growing needs of their populations. In cities, the main challenges of sustainable development are concentrated. So, there is a need to identify a new development model in order to make cities more sustainable. This necessity concerns all sectors, including the tourism one, which represents the third largest socio-economic activity in Europe. The tourism sector puts pressure on the city, increasing waste generation, noise and air pollution, and congestion in infrastructure and public areas. In addition, it is organized according to the linear economy model. This linearity is particularly visible in cities as people here tend to choose comfort over sustainability. In this framework, new approaches, strategies, and tools are required in order to make the tourism sector more sustainable, thus reducing its negative impacts on cities. In this perspective, the Human Circular Tourism (HCT) model is proposed. The aim of this study is to provide an operational framework consisting of recommendations, actions, and indicators to effectively operationalize the Human Circular Tourism model and to support public authorities (and other tourism stakeholders) in the identification of efficient policies in the tourism sector.
