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.

By 2020, the implementation of energy efficiency (EE) and renewable energy source (RES) measures in the public sector resulted in a cumulative energy savings of 228 GWh, and the cumulative CO2 emissions reduction was 56 kt. The values of both indicators lagged behind the annual target values by 26% and 12%, respectively. The 2020 targets were thus not achieved, which is largely due to the insufficient intensity of investments in the period 2015–2017.


The population in Slovenia is increasing. In the year 2021, it reached 2.109 million. The natural increase has slightly increased compared to 2020 but remains negative (-4.3 persons per 1,000 population). The net migration rate per 1,000 population has decreased to 1.2. The Slovenian population is aging, as indicated by the increasing old-age dependency ratio year by year. Population projections for the future show a significant decrease in the number of inhabitants in Slovenia by the year 2100 (to 1,888,364).


The Slovenian economy is gradually approaching the average level of development of the European Union. In 2022, the gross domestic product per capita in terms of purchasing power parity reached 92% of the EU-27 average, which is the highest so far. The support of the expansionary fiscal policy for the economy and the measures to assist the population during the epidemic and the high energy prices have greatly mitigated the impact of both crises.


The life expectancy in 2020 decreased due to the Covid-19 pandemic, which increased mortality rates, especially among individuals aged 60 and older. In 2021, life expectancy in Slovenia was 77.7 years for males and 83.8 years for females. Among the EU-27 countries, France (86.2) and Spain (86.2) recorded the highest life expectancy for females, while Sweden (81.3) had the highest life expectancy for males. The infant mortality rate per 1,000 live births in Slovenia in 2021 was 1.8, which is the lowest among all EU-27 countries.


In Slovenia, the number of companies registered under ISO 14001 and EMAS schemes, as well as the number of awarded EU Ecolabels, 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 EU Ecolabel (by 15). In terms of the number of awarded ISO 14001 certificates and EU Ecolabels per million inhabitants, Slovenia ranks above the EU-27 average on a European scale. However, its performance is slightly weaker in the field of EMAS, where Slovenia falls below the EU-27 average.


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.
