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.

Between 1961 and 2023, the average sea level along the Slovenian coast increased. A comparison of the ten-year moving averages from the first decade (1961–1970) and the most recent decade (2014–2023) shows that the average annual sea level has risen by approximately 10 cm over this period. From 1961 to 1995, there was no statistically significant trend in sea level rise. However, starting in the 1990s, the sea level began to increase more noticeably. Since 1995, the average annual sea level has risen by about 3.5 mm per year.

The indicator “Public Attitude towards Energy Consumption” points to a stagnation in the self-assessment of final energy consumption in households. The share of households that estimated their energy consumption as low or very low was increasing between 2010 and 2019, but then the trend reversed, and by 2025 it had decreased by 6 percentage points, returning to a similar level as in 2010. A similar situation is observed with households considering more efficient energy use.

The energy efficiency preference index among single-family homeowners is 46 (on a scale of 0 to 100), indicating untapped potential for improvement. The analysis reveals a divided market: approximately a fifth of households are completely passive, living in energy-inefficient homes and not considering renovation. Most of the remaining households are already on the path to greater efficiency, either by actively considering renovation or by having already updated individual elements such as windows, the facade, or the roof.

In 2023, agriculture accounted for 97.4% of total ammonia emissions. From 1990 to 2024, ammonia emissions in Slovenian agriculture decreased by 31.0% and by 15.7% since 2005. Slovenian agriculture is achieving the overall emissions target set out in the NEC Directive (a gradual reduction of at least 15% by 2030 compared to 2005).

Air

In Slovenia, emissions of persistent organic pollutants (polychlorinated biphenyl, polycyclic aromatic hydrocarbons, hexachlorobenzene, dioxins and furans) decreased between 1990-2023, primarily due to targeted legislation, improved control and use of best available technologies.

Air

Emissions of primary particles smaller than 10 µm (PM10), particles smaller than 2.5 µm (PM2.5), and all total suspended particles (TSP) decreased in Slovenia in the period 2000–2023 by 26 %, 36 %, and 11 %, respectively. The main source of particulate matter emissions are households, mainly due to the use of biomass for domestic heating.
