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 number of organised visits to outstanding natural features almost tripled in the 1992-2008 period, and in 2008, 882.000 tickets were sold. By far the most visited natural feature is the Postojna Cave.


In the period from 2005 to 2018, the gross nitrogen budget ranged from 43 to 70 kg per ha, with a minor reduction trend. The target value for 2020 is 53 kg N/ha. On average over the past five years this value has been achieved. Achieving the target will largely depend on farmers' interest in accepting organic farming and the requirements of the agri-environment-climate payments measures, as well as on the performance of the agricultural education system and public agricultural advisory services.


In the period after 2005, the consumption of nitrogen from mineral fertilizers has on average been slightly below the target value for 2020 (28,000 t N/year). In the period up to 2012, nitrogen consumption declined, after which it increased again in 2014 and 2015, and again declined in the period 2016–2018. The increased consumption in 2014 and 2015 is attributed to extremely favourable harvests and thus the increased need of agricultural plants for nitrogen.


Greenhouse gas (GHG) emissions per unit of milk production are characterized by large fluctuations from year to year, mainly affected by feed production conditions. In the period 2005−2018 there was no clear reduction trend (despite a clear trend over the longer period 1985−2018). Values after 2014 show a favourable trend towards the target value (0.786 kg CO2 equivalent in 2020).


In 2018, the share of renewable energy sources (RES) in the use of fuels in the tertiary sector increased by 2.1% compared to the previous year, amounting to 58.3%, which is the highest value in the period 2010−2018. The increase was mainly driven by a 9% decline in the use of fuels in the tertiary sector. The achieved share of RES lagged behind the indicative annual target value by 0.7 percentage points.


Specific greenhouse gas (GHG) emissions in the residential sector amounted to 9 kg CO2 eq/m2 in 2018, which is 7% less than the previous year. The reduction was mainly due to the reduction of GHG emissions from the use of fuels in this sector. Specific emissions were 10% lower than the indicative annual target value. In order to achieve the 2020 target they will have to be reduced by a further 3% or 0.1 kg CO2 eq/m2 per year, which in the period 2010–2018 was not achieved only in 2015, when the value of the indicator increased.
