This paper reports on a global study of the attitudes of students studying in senior year and first-year postgraduate tourism and hospitality subjects to tourism and its relationship with the environment and climate change. The study determined that students are generally concerned about environmental degradation, feel knowledgeable about climate change, are concerned that it will become an even larger issue in the next 5 years and, generally, appreciate that tourism is a major contributor to carbon emissions. Moreover, some 70% had changed their behavior in the past 3 years to reduce their environmental impacts. However, specificity of knowledge about the causes of climate change was limited, which is symptomatic of a broader lack of detailed knowledge about environmental degradation, which in turn translates into rather generic behavior changes. Most significantly, less than 13% of students have changed their vacation patterns out of concern for the environment, with only a small minority intending to modify their travel patterns in the future.
