Environmental indicators in Slovenia

Environmental indicators are based on graphs, maps and assessments and as such present environmental trends in Slovenia. The indicators represent one of the four pillars of our environmental reporting, and are prepared in accordance with the Environmental Protection Act. The Environmental Indicators in Slovenia website enables users to browse among 180 indicators. They are based on numerical data and they indicate the state, characteristics and trends of environmental development in Slovenia. They are prepared using a systematic approach based on data and monitoring, as shown in the information pyramid.

In comparison with the European average, the levels of transport charges in Slovenia are relatively low. The charges for the road freight transport subsystem are somewhere at the average level, while in the rail freight transport subsystem substantially below the average level of other European countries.


In 2020, taking into account only the production of energy from RES in Slovenia, Slovenia achieved a 24.1% share of RES in gross final energy consumption, which is 4.3 percentage points more than in 2005. To achieve a binding 25% national target share of RES under the Directive 2009/28/EC, Slovenia purchased the missing production from RES. The implementation of measures to prevent the spread of the SARS-CoV-2 virus has made a notable contribution to the significant increase in the share of RES in 2020, which has led to a sharp reduction in final energy consumption.


Primary energy consumption amounted to 6,334 ktoe in 2020 and decreased for the third year in a row, this time by 5.5%. The decrease was due to the reduction in final energy consumption caused by the measures for preventing the spread of SARS-CoV-2 virus, while the electricity production increased compared to the previous year. The structure of primary energy use was in 2020 continued to be dominated by liquid fuels (29.6%), followed by nuclear energy (26.1%), renewable energy sources (18.6%), solid fuels (16%) and natural gas (11.5%).


Final energy consumption amounted to 4,440 ktoe in 2020 and decreased for the second year in a row, this time by 9.2%. The reduction was mainly caused by the measures for preventing the spread of SARS-CoV-2 virus. There was a reduction in all sectors except households. In the period 2000‒2020, final energy consumption decreased by 2.2% and in 2020 reached the lowest value in the observed period. Most energy, 36%, is consumed in transport, followed by industry, households and other uses. The 2020 target has been achieved; final energy consumption was 13.2% lower than the target value.


Slovenia's import dependence is not decreasing and is about 50%. In 2020 it was exceptionally lower than in previous years due to the epidemiological situation. The most problematic is the import dependency on gaseous fuels, as Slovenia is heavily dependent on fuel imports from Russia.



Species diversity in Slovenia is stil considerably well preserved, distinctly higher in western part of the country. Without systematic monitoring on permanent plots it is impossible to recognize short term trends, but in some regions negative trends are result of landuse changes and impact of alien invasive species.
