Public procurement has a great impact on the economy of the whole country, as well as on the development of the local market, labor market and natural environment. The idea of sustainable procurement implies that public organizations should take those issues into account in their procurement process. However, the contracting authorities are reluctant to implement the rules of SP. We can point three barriers to applying this idea in practice: barriers: barriers related to the knowledge and skills of order preparers and control persons, psychological barriers (fears and attitudes) of order preparers and the financial barrier (higher costs of sustainable public procurement compared to other orders). Disse­mination of the application o sustainable procurement requires educational and promotional activities of the Public Procurement Office and other state institutions.
