Sustainable transport is a highly debated topic in the context of reducing the carbon footprint. Among other things, this article provides an overview of different perspectives on sustainable transport behavior. The researchers focused on the Czech consumer and some aspects of their sustainable transport behavior. The aim of this paper is to present the results of a questionnaire survey on a representative sample of Czech consumers. The investigation focused mainly on the frequency of car use for transport, popularity and options for carsharing or public transport. Among others, factors hindering the use of public transport were identified. Furthermore, the researchers' attention was focused on the perceived environmental friendliness of different modes of transport. The results show that the Czech consumer perceives eco-friendly modes of transport positively, but he himself does not behave very sustainably in personal transport for various reasons, which will be presented in this article.
