In Slovenia, there is an acute problem of combating the harmful effects of economic activities that worsen the living conditions of people, animals and plants. The government takes measures to encourage residents to stay in their native settlements and take care of their arrangement and development, preservation of natural resources and a comfortable environment for people. Numerous public organizations of the civil society play an important role in this issue. This article outlines the features of the modern environmental policy of Slovenia, pursued within the framework of the general line of the European Union, aimed at phasing out of carbon fuels and transition to renewable energy sources. The Slovenian official documents, setting out the country’s environmental strategy, the progress in the implementation of plans for energy and climate measures until 2030, the current state of the energy sector and its compliance with planned tasks, are reviewed. The author gives an assessment of the effectiveness of the environmental policy pursued in Slovenia and its possible results. It is stated that although the indicators of improving the environmental situation are gradually increasing, the emission of harmful gases is decreasing, the efficiency of the use of energy and raw materials is increasing, Slovenia still lags behind the European average in most of these indicators. At the same time, it has a relatively high share of renewable energy sources in its total production. This is achieved through budget subsidies for energy produced from renewable energy sources, so that its price does not exceed the market level. Significant financial resources are spent to apply a wide arsenal of stimulus measures, so the government is forced to seek opportunities to further increase funding for environmental activities, through European Union funds as well, including assistance to fight the coronavirus pandemic.
