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.

At the end of 2021, the total floor area of energy-renovated buildings in the public sector amounted to 1.92 million m2, and a year later to 2.15 million m2. Within OP EKP 906,400 m2 of total floor area were renovated by the end of 2022. According to the first estimates, the energy-renovated floor area at the end of 2023 will be at the level of the OP EKP target value, while the target from OP EKP for the energy renovation of buildings owned and occupied by the central government will not be achieved.


Slovenia has participated in the European Mobility Week (EMW) initiative from the very beginning. Its implementation has become an important form of promotion and encouragement of sustainable mobility planning in the last decade. Since the beginning of the implementation in 2002 136 Slovenian municipalities have participated in the EMW initiative at least once, and 7 municipalities every year. The number of participating municipalities has increased over the years and has already reached almost half of Slovenian municipalities.


By 2021, the implementation of energy efficiency (EE) and renewable energy source (RES) measures in the public sector resulted in a cumulative energy savings of 255 GWh, and the cumulative CO2 emissions reduction was 63 kt. The values of both indicators thus still lagged behind the 2020 target values, which is largely due to the insufficient intensity of investments in 2016 and 2017. In 2022, according to currently available data, energy savings of 33 GWh were achieved, and the CO2 emissions reduction was 7.4 kt.


In 2021, the leverage of incentives in the public sector amounted to 31.8 euro cents of subsidy for 1 euro of investment. The annual 2020 target value of 33 euro cents was, thus, reached a year late. Compared to the previous year, 2.8 euro cents less subsidy had to be allocated for 1 euro of investment, as the financial leverage of the Eco Fund's incentives decreased again, this time by 3.3 euro cents. According to currently available data, the leverage of incentives in the public sector has increased again in 2022, to 38.6 euro cents of subsidy for 1 euro of investment.


Phytoplankton biomass, expressed as chlorophyll a concentration, reflects nutrient loading in the marine environment. Chlorophyll a concentrations shows a trend towards improvement in the status of the Slovenian sea, as the ecological status has been assessed as high or good over the last period.
