Position of EU as a second energy consumer and fifth refiner in the world makes it a natural leader in the area of demand management and promotion of renewable energy. At the same time it faces the challenges of energy supply as well as the anes of forecasting and analyzing the effects of increasing energy consumption on economic development and the environment. As a part of the solution the concept of integrated quality and its promotion to the development of an integrated quality management system operations and environmental protection is imposed . The study had as its basic hypothesis that the integrated system of quality management is underlying factor in the competitive advantages of oil and oil products on the EU market. ln the empirical part of the research a survey is conducted which included 39 oil companies from inside and outside the European Union participating in the trade with the EU. Research has shown that the benefits of quality management environmental protection and safety are identified by companies from the whole sample. and integration management system is implemented in most of them. The basic hypothesis of integrated system of qualit~ management as the underlying factor in the competitive advantages of oil and petroleum products to the EU's macroeconomic stability and security of the Union was confirmed. Also confirmed was the hypothesis of the relationship of the integrated quality management system with customer satisfaction and preservation of the environment in the context of sustainable development of the internal EU market. as well as links to the security and stability of the EU and its connections with third countries. On the other hand. the hypothesis on the contribution of the integrated quality management systems for reducing the degree of dependence on imported fuels, as well as the impact of an integrated quality management system to mitigation of the recession in the economy of the EU have not been confirmed. The European Union experience in the construction and application of quality standards for energy should be used in preparation of strategic documents of the macroeconomic development in Croatia w·here quality management system has a significant place. We believe that the results of this research could be helpful in defining energy policy in our country. especially because we are at the end of the process of EU accession negotiations.
