The journal Sustainability has previously published special issues on sustainable tourism and on sustainable cities (both in 2014). This special issue presents recent insights from combining the two research topics. There is some convergence with respect to core challenges that sustainable urban tourism is facing. Firstly, relating to social sustainable development, there is the tension between the quality of life for residents in different ways and the development of cities to benefit the tourism industry. Secondly, relating to environmental sustainable development, there is the tension between residents and their desire for good local environmental standards and visiting tourists that create a number of over-tourism related local environmental problems. Thirdly, there are the challenges that so far have received less attention, but obviously are expected to become crucial in the years to come: The double climate change provides risks to cities from a changing climate and from more ambitious climate policies to come.
