The current challenges and barriers in the tourism sustainability, such as high energy use, extensive water consumption and habitat destruction, are first reviewed. Then the key cross-disciplinary elements in sustainable tourism, including green energy, green transportation, green buildings, green infrastructure, green agriculture and smart technologies, are discussed. To overcome the challenges and barriers, a few implementation strategies on achieving sustainable tourism from the aspects of policy/regulation, institution, finance, technology and culture are proposed, along with the framework and details of a key performance indicator system. Finally, prospects of the potential for tourism to contribute to the transformative changes, e.g., a green economy system, are illustrated. This paper shine a light on issues of importance within sustainable tourism and encourage researchers from different disciplines in investigating the inter-relationships among community/culture, environment/ecology, and energy/water/food more broadly.enGreen building; Green infrastructure; Renewable energy; Smart technology; Sustainable transport; Water-energy-food nexus[SDGs]SDG7[SDGs]SDG8[SDGs]SDG12Benchmarking; Energy policy; Green buildings; Green infrastructure; Renewable energies; Smart technology; Sustainable transport; Water energy; Sustainable development; alternative energy; ecotourism; environmental economics; green economy; policy approach; sustainability; sustainable development; tourism development; agriculture; biodiversity; carbon footprint; case study; cultural factor; ecotourism; environmental monitoring; environmental policy; habitat; human; human impact (environment); nonhuman; pollution control; priority journal; public-private partnership; renewable energy; Review; sustainable development; Taiwan; tourism; traffic and transport; travel; waste management; water pollution; water supplyjournal article10.1016/j.scitotenv.2018.04.13429677671WOS:000436494400045https://doi.org/10.1016/j.scitotenv.2018.04.13443947513
