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.

Bad

In the last decade (2012–2021), on average around 135,000 tons of hazardous waste was generated annually in Slovenia. This waste accounted for 1% to 3% of all generated waste in Slovenia. Since they contain substances harmful to the environment and health, they must be collected, recovered or disposed of separately from other waste.

In the last decade (2012–2021) each resident of Slovenia annually discards on average around 3.5 kg of hazardous municipal waste, of which the majority in waste electrical and electronic equipment (63%).

Bad

Road goods transport has been growing sharply since Slovenia joined the EU, as the volume of tonne-kilometres of the Slovenian transport carriers increased by more than 2,5 times in the period 2004-2019. After the pandemic-related halt, the volume has returned to its previous levels.The growth of freight transport and transit in Slovenia has been constant in road, rail and maritime transport since independence, despite intermediate economic problems in the EU during the recession 2008-2014. The exception is air freight transport, which has stagnated for years after a sharp decline in 2008.

Good

In the period 1992–2023 nitrogen surplus in Slovenian agriculture decreased. Trend analysis for this period shows that gross nitrogen surplus decreased on average by 1.4 kg N/ha per year or by 54%, and the net surplus by 1.2 kg N/ha per year or by 85%. The lower surplus was mainly due to a 43% increase in nitrogen removal by crops and a 6% 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.

Neutral
Air

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 2000-2022 in Slovenia by 23 %, 33 % and 8 %. The main source of emissions of particulate matter are households, mainly due to use of biomass for domestic heating.

Bad

The frequency of agricultural drought in Slovenia has been increasing in recent decades. Since year 2000, natural disaster due to drought was declared seven times in Slovenia, the most severe of which occurred in 2003, 2012, 2013, 2017 and 2022. Drought keeps occurring with increasing intensity and in areas and seasons where there have not been problems in the past. An additional risk for drought damage in agriculture present rapidly developing droughts in summer (so-called "flash droughts"), which occur during heat waves.

Neutral

2024 was the second consecutive year with above-average water abundance, with no surface water drought observed in any season. However, over the past twenty years, hydrological droughts of surface waters have become both more frequent and more intense compared to previous periods, with greater variability between individual years. Very dry and very wet years now alternate with periods of hydrologically normal conditions. The drought intensity during the growing season has become more frequent, though it has been less severe in the past decade than in the previous one.
