Tourism under a life cycle thinking approach: A review of perspectives and new challenges for the tourism sector in the last decades

Abstract: Sustainable tourism should be promoted as a new system for the sustainable management of resources from a socioeconomic and environmental point of view. For this purpose, it is necessary to develop a tool capable of assessing the impacts associated with the sector and to identify which actions are currently being addressed in order to achieve the desired sustainability. This timely study aims to describe the current framework of Life Cycle Assessment (LCA) and its application to the tourism sector. To address these questions, a total of 83 documents (77 reviews and 6 international reports) were evaluated, assessing the geographical distribution, the temporal evolution of the publications, as well as the most relevant characteristics of the tourism industry articles were evaluated such as, life cycle inventory (LCI), system boundaries, functional unit (FU), methods, environmental indicators and impact categories considered. The study identifies key recommendations on the progression of LCA in tourism sector. As important results, it stands out that 94 % of articles were from the last decade and 21 % of the articles reviewed cover sustainable tourism term, considering the three dimensions. This review showed that in LCA studies the most common method was CML 2001; the most widely used environmental indicator was the Carbon Footprint (CF) and the Global Warming Potential (GWP) was the impact category used in all the studies. Hence, LCA is a highly effective tool capable of assessing direct and indirect carbon emissions in tourism as well as the socioeconomic and environmental impacts generated in this sector. COVID-19 pandemic is also an object of discussion in the framework of the sustainable tourism together with advocating support for the eco-labelling and digitalisation of the tourism experiences as valuable tools to minimize environmental negativities, to promote mechanisms to access green markets and to frame successful synergies.
