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.

In recent years, the amount of wastewater treated by secondary or tertiary treatment processes increased, while primary treatment processes have closed. The amount of wastewater treated through secondary treatment processes increased by 150 % since 2000 or from 30 million m3 (in 2000) to almoust 45 million m3 (in 2019). There were almost no tertiary wastewater treatment processes in Slovenia in 2000, and in 2019, 72% of wastewater or 113 million m3 of wastewater was treated by tertiary process.

Good

In 2021, greenhouse gas (GHG) emissions from sources according to the Regulation (EU) 2023/857 increased by 5.5% compared to the previous year and were lower than the annual target by 8.6%, which means that the target was achieved. GHG emissions decreased in the waste and electricity and heat production sectors, and the most in the consumer sector. In all other sectors emissions increased, with the exception of the agriculture, where they remained at the 2020 level.

Neutral

Since 2012, the installed capacity of the systems for the production of electricity from RES has increased by 47.3%. More than half of this increase, 24.7%, was achieved in the last three years. The indicator is currently on a trajectory of achieving the indicative targets until 2030 set in the National Energy and Climate Plan (NECP).

Neutral

Although a quarter of the newly registered personal cars in Slovenia are electric or hybrid, their share among all personal vehicles is only around 3%. This is due to the fact that households rarely decide to purchase new cars, resulting in a high average age of cars over 10 years, and it will take a long time for our vehicle fleet to become less energy-intensive. Slovenia ranks in the bottom quarter of European countries by the share of first registrations of new personal electric vehicles.

Bad

Frequency of groundwater drought is increasing in recent decades in alluvial aquifers. 8 out of 10 years with highest intensity of groundwater drought in period 1981-2023 occurred after year 2000. Groundwater droughts with higher intensity is characteristic for winter while milder groundwater droughts mostly occur at the beginning of autumn. Groundwater drought intensity is also increasing seasonally with time between June and September when groundwater use is pronounced.

Good

The vast majority of registered personal vehicles are still powered by conventional fuels (petrol and diesel). The proportion of vehicles with alternative propulsion systems has doubled from 2019 to 2022, yet it remains very small.
