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 state of wildlife in Slovenia is favourable; larger epidemics have not been identified. The number of herbivorous ungulates as well as wild boars has decreased. An increase in wildlife losses due to road kill raises concerns. The total amount of damage caused by wildlife has decreased.

Wildlife management includes all animal and plant species. Regulation of wildlife populations is based on game management plans that are submitted for adoption to the Ministry of Agriculture, Forestry and Food by the Slovenia Forest Service in accordance with a prescribed procedure.


According to data from the Ministry of Infrastructure, a total of 135 self-supply devices were connected in 2016, 720 in 2017, and another 1,302 in 2018. In 2016, 130 solar power plants and 5 hydroelectric power plants were connected with a total nominal power of just under 1.1 MW. In 2017, 718 solar power plants and 2 hydropower plants were connected, and the total nominal power of the connected units was slightly under 6.5 MW. In 2018 there were 1,299 solar power plants connected, 2 hydropower plants, and, for the first time, also 1 wind power plant.


Normalized electricity generation from renewable energy sources (RES) increased by 11% compared to 2010 and by 19% compared to 2005. In order to achieve an indicative target in 2020, an increase by more than what was achieved throughout the whole 2005‒2018 period is required. The indicative target for the production of electricity from renewable energy sources is set in the National Renewable Energy Action Plan 2010−2020 (NREAP).


After recording annual growth in 2016 and 2017, the total emissions in the EU-ETS sector decreased in year 2018 by 1.2% compared to the previous year. The decrease resulted from smaller emissions from energy industries. The total emissions in the EU-ETS sector decreased by 26% in the period 2005‒2018. At the EU-28 level, this sector adopted the legally binding target of reducing GHG emissions by 21% by 2020 compared to the 2005 level. That is an EU-28 common goal and is not further differentiated across Member States. Slovenia does not have a specific target for this sector.


In 2018, the share of renewable energy in gross final energy consumption in Slovenia was 21.1%, i.e. 5.1 percent points higher than in 2005. The trend towards Slovenia’s 2020 target under Directive 2009/28/EC is severely inadequate and is also below the indicative trajectory under the National Renewable Energy Action Plan 2010-2020 (NREAP). An increase in the renewable energy share by 3.9 percent points in 2019 and 2020 will be a very demanding task; for comparison, the share increased by only 0.7 percent points in the period 2010‒2018, i.e. since the NREAP was adopted.


In 2018, emissions productivity*1 in Slovenia improved. But despite the progress made in the last two years, Slovenia (compared to EU) is still encountering slow progress in terms of emissions productivity. The link between economic development and measures to reduce greenhouse gas (GHG) emissions needs to be further strengthened.
