Sustainable tourism can combine recreation for people, economic opportunities for entrepreneurs, and environmental protection, but for mountain tourism, climate change and the predicted reductions in snowfall require urgent action. Therefore, this study aims to identify sustainable mountain tourism strategies and consumption patterns using a multi‐criteria decision methodology and data collected through an online survey and expert opinions. The results show the importance of stakeholder engagement and the relevance of three strategies: (i) zero‐emission lodges; (ii) energy communities, and (iii) zero‐emission ski lifts. As well as pointing out the need for sustainability awareness and education. While respondents pay a great deal of attention to sustainability, the analysis highlights three policy interventions to safeguard mountain tourism: (i) financing the conversion of facilities; (ii) expanding infrastructure to reach mountain resorts, and (iii) rewarding consumers for choosing a certified zero‐emission resort.
