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.

Slovenia has some of the greatest subterranean biodiversity in the world. The aquatic fauna, with its 200 species, is by far the richest, while the terrestrial fauna, with 150 species, is second only to the more southern areas of the Dinaric karst. Five Slovenian cave systems have been listed among the 20 richest cave systems in the world. The Postojna-Planina Cave System, with its 50 aquatic and 35 terrestrial species is by far the most abundant. The Cave Protection Act protects the subterranean environment as a whole.


According to the Ministry of Infrastructure (MOI) data, a total of 135 self-sufficiency devices were connected in 2016 and 720 in 2017. 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 connected devices was close to 6.5 MW.


From 2010, normalized electricity generation from RES increased by 11% and from 2005 by 19%. In order to achieve an indicative target in 2020, an increase is required for more than it was achieved throughout the whole 2005–2017 period. An indicative target for the production of electricity from renewable energy sources is set by AN RES for the period 2010–2020.


In 2017, 63% of all municipalities with district heating (DH) had energy efficient DH systems, i.e. systems that meet one of the criteria defined in the Article 322 of the Energy Law. Compared to the previous year, the share decreased by 4 percentage points and was lagging behind the 2020 target by 37 percentage points. In energy efficient systems, 77% of all heat from DH systems was produced in comparison to 84% the year before. In the fuel consumption structure, the dominance of coal and natural gas increased from 81 to 84%.


The total emissions in the EU-ETS sector after 2016 recorded annual growth in 2017 as well. After 6% growth in 2016, total emissions in the year 2017 increased by 1.4% compared to the year before. Growth is the result of higher emissions from industrial processes and manufacturing. At EU-28 level, this sector has adopted a legally binding target of reducing GHG emissions by 21% until 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.


Areas of fields and gardens in measures that require fertilization based on rapid soil or plant tests, have significantly exceeded the target value set by the 2014-2020 Rural Development Program over the past three years.
