This article discusses the relationship between a consumer lifestyle and the environment. The willingness to adapt to a sustainable lifestyle was tested through a questionnaire among students of Mendel University in Brno, who are theoretically well-informed people. Overall, 417 students answered, i.e., 19% of the respondents. The students generally recognised the need to address environmental issues, and 90.6% intended to change their lifestyle in this direction. Among the barriers, they mentioned in particular lack of time, lack of financial resources, lack of specific information and insufficient conditions. Addressing this issue requires close co-operation in education between governmental and non-governmental organisations in both the public and private sectors. The COVID-19 pandemic has affected the situation in that it has drawn attention to the response of local companies to the global problem.
