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.

Household electricity consumption is increasing and amounted to 3,000 GWh in 2009. The share of households equipped with electricity-consuming appliances is increasing as well. These include e.g. dishwashers, clothes dryers, mobile phones, CD players, microwaves, and personal computers. Despite the improved energy efficiency of some appliances, electricity consumption has not decreased, as the number of household appliances continues to increase rapidly, which also contributes to excessive quantities of waste.


The indicator mainly shows the unidentifiable direction of development. The majority of data were available only for a limited period and therefore, reliable estimation of trends is not possible. Cereals are the predominant group of crops in Slovenia. Areas for growing green fodder crops and industrial plants are increasing, while the production of root and tuber crops has stabilized on two percent of arable land. A slow diversification of crop species is observed; particularly favorable is the increase in the share of legumes.


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 – 2020 in Slovenia by 28 %, 30 % and 26 %. The main source of emissions of particulate matter are households, mainly due to use of biomass for domestic heating.


Heavy metal emissions in Slovenia significantly decreased between 1990 and 2020. This can be largely attributed to the implementation of the EU legislation, improved surveillance and use of the best available technology. 


One of the main sources of greenhouse gas emissions in Slovenia is road traffic, as passenger vehicles contribute as much as 20 % of all greenhouse gas emissions. It is estimated that, due to the smaller role of public passenger transport in Slovenia, it is necessary to achieve as much as 2/3 reduction of GHG emissions by electrifying the vehicle fleet, which dictates the replacement of existing vehicles with fossil fuels. with electric vehicles (battery and plug-in hybrids EV).


Emissions of total ozone precursors in Slovenia decreased by 62 % in the period 1990 to 2020. Emissions of nitrogen oxides decreased by 66 %, carbon monoxide by 70 %, non-methane volatile organic compounds by 54 % and methane by 25 %. The reason is mainly the introduction of more stringent emission standards for motor vehicles. This measure contributed to a significant reduction in emissions of nitrogen oxides and carbon dioxide from road transport which is the main source of ozone precursors.
