This paper investigates under which conditions implementation of Industry 4.0 in the hospitality sector could help to combat climate change. The paper takes the form of a systematic literature review to examine the main pillars of Industry 4.0 in the hospitality industry and discuss how these technologies could help combat climate change. We propose five conditions under which Industry 4.0 could help to combat climate change. First, in the hospitality industry, increased use of Industry 4.0 technologies induces an increase in energy efficiency and a reduction of GHG. Second, increased use of Industry 4.0 technologies induces a reduction in water consumption and an increase in water use efficiency. Third, increased use of Industry 4.0 technologies induces a reduction in food waste. Fourth, increased use of Industry 4.0 technologies can promote Circular Hospitality 4.0. Fifth, increased use of Industry 4.0 technologies helps to reduce transport and travel. Hospitality Industry 4.0 technologies offer new opportunities for enhancing sustainable development and reducing GHG emissions through the use of environmentally friendly approaches to achieve the Paris Agreement objectives.
