Since the United Nations approved the eight Millennium Development Goals in 2000 and, 15 years later, the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs), the highest political institutions in the world have not stopped worrying about achieving the sustainability of the planet. Also in 2015, the European Commission prepared the European Union Action Plan for the Circular Economy, seeking a transition towards a less linear economy, in which products, materials, and resources are kept in the system for as long as possible and in which the generation of waste is minimized. Since then, the European Union has continued issuing reports and communications to accelerate this process in search of a circular economy, making continuous references to the fact that, through circular economy initiatives, the SDGs would be fulfilled. In this context, the objectives of this paper are 1) to determine, through exploratory factor analysis and correlation analysis, whether there is a statistically significant relationship between circular economy initiatives undertaken in the EU and compliance with the SDGs; 2) to check, through a cluster analysis, if there are homogeneous groups of countries worldwide in terms of compliance with the SDGs; and 3) using this same technique, to check whether the countries that make up the EU achieve similar results in terms of compliance with the SDGs.

The health crisis caused by the pandemic COVID-19 has been of such magnitude that the drop-off in economic and tourist activity in most countries is generating an economic crisis with consequences that are still difficult to measure. The present work analyses the origins and evolution of the coronavirus pandemic and reviews the literature related to the impacts and recovery strategies that were implemented in previous crisis situations affecting the hotel industry. In order to focus the study on one country, Spain was selected based on tourism indicators, the importance of tourism for this country and the importance of Spain as a leader in international tourist destinations. The influence of the pandemic on the Spanish tourism sector and, more specifically, on its hospitality industry is explored in depth. In addition, the main initiatives to support the tourism and hospitality sector that have been undertaken at the global, European and national levels are highlighted and, finally, the response and recovery strategies of the five largest Spanish hotel chains to guarantee a COVID-19-free stay in their facilities and to recover the accommodation activity are discussed.

The European Union (EU) is trying to accelerate the transition from the current linear economy to a circular economy (CE). In fact, the CE is considered a tool to attain sustainable development goals (SDGs). In this sense, this paper aims at analysing the interaction between the CE and SDGs in the context of the new 2030 Agenda and the European CE strategy; thus contributing to the scarce empirical literature that links the potential of the European CE strategy to the achievement of the SDGs set by the 2030 Agenda. Three specific research questions have been formulated. First, could the objectives defined in the 2030 Agenda be considered homogeneous, and could they uniquely measure the concept of sustainability? Second, are there significant correlations between the implementation of a CE in the EU and the SDGs? Finally, is the behaviour of the 28 countries that make up the EU homogeneous in terms of the results of the initiatives aimed at the implementation of a CE? From these questions, nine hypotheses are put forward concerning the possible relationships between a CE implementation and the fulfilment of SDGs in the EU. Using a correlation analysis, an exploratory factor analysis, and a cluster analysis, it has been demonstrated that (a) SDGs do not univocally measure the concept of sustainability; (b) there are significant relationships between CE and SDGs in the EU; (c) the behaviour of these European countries is not homogeneous.

The circular economy (CE) is considered a possible solution to problems, such as the increasing global demand for resources, climate change and worldwide pollution. CE can help to transform the hospitality industry from its current linear model of production to a circular one. However, there is a lack of research on circular tourism, therefore, this paper’s main purpose is to shed light on CE strategies—reduction, reuse, recycle, redesign, replace and rethink—developed in the tourism sector, as well as the tourism sector’s CE initiatives by means of a business case analysis method. This qualitative multicase analysis allows us to comprehend the CE practices deployed by large hotel chains, thus identifying the CE strategies and best practices. The results show that the main strategies adopted are the reduction, recycle and reuse, in this order. Nevertheless, the remaining strategies have yet to be adopted in the mainstream. This research emphasises the need to promote the CE in the hospitality industry, especially among independent hotels.

Certifying quality systems has become standard practice in a wide range of companies the world over. However, studies on these systems' underlying motivations and these motivations' effects on performance have focused primarily on industrial firms, leaving the service sector largely unexplored in this regard. In this article structural equation modelling is used to analyse the reasons that underlie certification and the effects of these motivations on performance parameters within the hotel industry. The findings in this study show certain significant differences from the academic findings for industrial companies. The conclusions may help managers of hotel companies to better incorporate quality as a strategic, proactive tool with which to confront changing or adverse economic circumstances.
