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 2020, the amount of incentives for the implementation of measures related to energy efficiency (EE) and renewable energy sources (RES) in non-ETS industry amounted to almost EUR 5.9 million, which is four times more than the previous year and by far the highest in the observed period.


In Slovenia, the number of companies registered under ISO 14001 and EMAS schemes, as well as the number of awarded co-label flowers, is gradually increasing. In the year 2021, the number of ISO 14001 certificates significantly increased (by 63), while in 2022, there was a rise in environmental eco-labels flowers (by 15). In terms of the number of awarded ISO 14001 certificates and eco-label flowers per million inhabitants, Slovenia ranks above the EU-27 average on a European scale.


The Happy Planet Index (HPI) ranks countries based on how effectively they provide their citizens with the conditions to live long and happy lives without excessive depletion of natural resources. Slovenia ranked 53rd in the world according to the HPI in 2019 (out of 152 countries included in the calculation) and 12th among the EU-27 countries and the United Kingdom. Despite an increase in per capita ecological footprint in Slovenia between 2016 and 2019, the HPI value has increased from 44.5 to 47.9. This is due to a slightly longer life expectancy and higher life satisfaction.


Between 1980 and 2021, extreme events related to climate change in EU-27 resulted in an economic loss of EUR 560 billion, of which EUR 56.6 billion from 2021. Climate extremes are becoming more common. Without further action, even greater economic damage is expected in the future. This trend is also noticeable in Slovenia. The difference between the period 1980-2015 and 1980-2021 is as much as € 2,38 billion. In comparison to the previous period 1980-2020, the difference is € 1,01 billion.


In 2021, the levels of benzo(a)pyrene at all urban monitoring sites reached the target value. Annual trends of benzo(a)pyrene levels show that the highest levels are measured during the heating season. In summer, levels are significantly lower at all locations.


Air pollution with PM10 was the lowest in 2021 since we have been carrying out measurements. For the first time, at no monitoring site did the sum of exceeding the daily limit value for PM10 (50 µg/m3) exceed the number of 35, which is allowed for the whole year. Even the annual limit value for PM10 in 2021 was not exceeded at any monitoring site.
