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.

The Green Key is an international label for the environment, which is awarded to tourist accommodations and catering establishments that strive for environmental responsibility and sustainable behavior in the tourism industry. In Slovenia, 143 siteswere certified in 2022. In 2021, 3,165 sites were certified in the European Union, and 3,165 around the world.


The performance of EU countries in the field of eco-innovations is monitored by a composite index that includes 12 indicators from five thematic areas. Slovenia is ranked as an average eco-innovation performer. The values of the indicator are gradually improving and show the progress of the eco-innovation index, but they still remain below the EU average. The target value for Slovenia has not been set.


The share of renewable energy sources (RES) in the use of fuels in industry amounted to 11% in 2021, which was 0.7 percentage point behind the annual indicative target value. The 2021 indicative target was thus not achieved. In order to achieve the target of 30% of RES in the use of fuels in industry in 2030, the share of RES will have to increase by 19 percentage points or by about approximately 2 percentage points per year.


GHG emissions in industry decreased slightly in 2021 compared to the previous year. Since 2009, there has been no noticeable trend of decreasing GHG emissions in this sector.

GHG emissions in the ETS subsector of industry sector decreased for the third year in a row and were 4.2% lower than the previous year. GHG emissions in the non-ETS subsector of the industry sector increased by 5.5% in 2021 compared to the previous year. In 2021, the share of emissions from the ETS subsector was 57.4% of all emissions in industry sector, and the share of non-ETS emissions was 42.6%.


In 2021, 62% of the population was connected to the municipal wastewater treatment systems with secondary or tertiary treatment, which do not produce GHG emissions. Compared to the previous year, the share decreased by a small percentage point, moreover, the share has remained almost unchanged since 2017.


In 2021, the amount of incentives for the implementation of measures related to energy efficiency (EE) and renewable energy sources (RES) in non-ETS industry amounted to EUR 4.1 million, i.e. 30 % less than the previous year. In 2022, according to currently available data, the amount was further reduced to EUR 1.1 million.
