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 amount of packaging waste has stabilized in recent years at about 100 kg per capita per year. In 2014, every resident of Slovenia produced 102 kg of packaging waste, which is a few kilos more than in the four preceeding years.

Recovery of packaging waste has been increasing and in 2014 stood at 88%. Recycling is also increasing and in 2014 it reached 70%. Slovenia has reached the EU target – to reuse at least 55% of all packaging materials by the end of 2012.


As of 2022, the Potentially Contaminated Sites (PCS) inventory in Slovenia includes 671 sites that are a potential source of pollution due to past or present activities. With the establishment of the first database, Slovenia has taken the first of six steps toward systematic management and monitoring of contaminated sites. An analysis of the degree of environmental sensitivity and threat to human health due to potential contamination revealed that priority treatment is urgent for 35 sites and very urgent for 196 sites.


In the period 1992–2022 the consumption of mineral fertilizers in Slovenia was reduced by 38%. In the same period the consumption of plant nutrients (N, P2O5, K2O) per hectare of utilized agricultural area also reduced by 30%. The average consumption per hectare of utilized agricultural area was 61 kg N, 25 kg P2O5 and 31 kg K2O. In the period 2012–2019 the average consumption of nitrogen in Slovenia was lower (57 kg N/ha) than in EU member states (63 kg N/ha).


The emission of primary particles, smaller than 10 µm (PM10), particles smaller than 2.5 µm (PM2.5) and all total suspended particles (TSP) have decreased in the period 2000 – 2021 in Slovenia by 21 %, 29 % and 20 %. The main source of emissions of particulate matter are households, mainly due to use of biomass for domestic heating.


In 2023, Slovenia recorded a decrease in the number and total area of functionally derelict areas (FDAs): 1070 FDAs were registered with a total area of 3225.44 ha. This brings the situation closer to that of 2017, with a decrease of 62 in the number of FDAs and 469.83 ha in total area, compared to 2020.


In the period 1992–2021 nitrogen surplus in Slovenian agriculture decreased. Trend analysis for this period shows that gross nitrogen surplus decreased on average by 1.5 kg N/ha per year or by 54%, and the net surplus by 1.5 kg N/ha per year or by 87%. The lower surplus was mainly due to a 50% increase in nitrogen removal by crops and a 4% decrease in nitrogen input per hectare of utilized agricultural area. A lower excess of nitrogen indicates better nitrogen management in agriculture and consequently a reduction in emissions of nitrogen compounds into the environment.
