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 assessment of external costs of transport in Slovenia for 2002 varies between 6 and 9.8 % of GDP, which is at the level of the EU-15 average (7 %). The majority (over 90 %) of all external costs of transport in Slovenia are caused by road transport.


Both the residents of the EU-27 countries and the residents of Slovenia are only partially aware of the problem of increasing transport and its consequences for the environment and health. Public awareness of the impact of transport on the environment is still relatively low, although the differences between European countries are considerable. People's awareness of the environmental problems of transport does not automatically lead to changing their travel habits, even though this would contribute to their better health.


Electricity consumption in households is increasing, especially in the last two years, and in 2021 it amounted to 3,803 GWh. The share of households equipped with goods that require electricity for their operation is also increasing. For example dishwasher, tumble dryer, mobile phone, microwave oven, personal computer as well as heat pump and air conditioner.


In Slovenia, over 70% of the energy supply is available to end users. The share is by far the most affected by the efficiency of electricity and heat production.

In the production of electricity and heat in thermal power plants, less than half of the energy invested was lost in 2021. Compared to the EU-27 countries, Slovenia was in the bottom third of countries.

In 2020, the production of electricity from CHP accounted for just under 7% of the total production in Slovenia.



In Slovenia, in 2020 the external costs estimate of electricity production ranges from 0.8 - 2.8 € c2000 / kWh. Despite growing environmental awareness, the price of electricity still does not reflect all external costs. Due to incorrect price signals, which are the result of the current situation on the electricity markets, energy sources in Slovenia remain suboptimally used.


In 2012, the share of electricity generated from renewable sources in gross electricity consumption was 29.5%, which was 4.1 percentage points below the target value set for 2010. The share increased in comparison to the previous year. This is largely a consequence of higher generation of electricity from renewable sources, particularly due to higher river discharges, as gross electricity consumption was almost the same as a year earlier. In 2012, electricity generation from hydropower represented 90% of total electricity generated from RES, while its share has been in gradual decline.
