The aim of the research was to assess the developmental priorities of municipalities as they reflect the current policy objectives of the Czech Republic and the European Union, with a focus on the Green Deal and accelerating developmental changes in the external environment. To this end, the key priorities of the Just Transition Fund programme, which is designed for structurally affected regions in the Czech Republic, were selected. Specifically, these included themes in the areas of energy, waste management, transport, brownfield revitalisation and education. The method for obtaining information on the attitudes of municipalities was a questionnaire survey in 160 municipalities within the Ústí nad Labem Region, which also helped to assess the differences between small and large municipalities. The research found that municipalities are prioritising development in energy and waste treatment. At the same time, small municipalities, with under 1000 inhabitants, are slower to develop projects than larger municipalities, and larger municipalities were also more aware of the importance of sustainability issues for future municipal development.
