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 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.


In 2018 PM10 pollution was comparable to years before. The level of concentration is highly dependent on weather conditions. Exceedences of the daily limit values occur especially in the cold part of the year due to heating and due to meteorological conditions, which are extremely unfavourable in winter.  In 2018 at six measuring sites, PM10 concentration were above the allowed annual number of 35.  The annual limit value for PM10 as well as for the PM2,5 was not exceeded at any measuring sites.


Temperature in Slovenia increases faster than global average. Increase in the annual average temperature is most evident in last three decades. Warming of atmosphere will continue according to the climate change projections. The result of warming is an increase in sea level (due to melting of glaciers), increase in level of the greenhouse gases in atmosphere (contributes to warming), and many extreme weather and climate events (like floods, droughts, hail and heavy wind), what will result in the quality of our lives.


Lyme borreliosis (LB) and tick-borne meningoencephalitis (TBE) are the most common vector-borne diseases transmitted by ticks. In Slovenia, from 3,000 to over 6,000 patients with LB were registered annually, and 250 TBE cases annually in the period from 2008 to 2017 (maximum in 2013 – 309 cases, the lowest number of cases was in 2015 – 62 cases only). Living or working in the environments where there is a potential for infection is one of the most important factors for infection with LB and TBE.


Foodborne diseases remain an important public health challenge and they are an important cause of morbidity and mortality worldwide.

During 2013–2017 Slovenia reported 424 different outbreaks. The most common outbreaks were those with contact transmission where Norovirus was the most common cause of confirmed, single-etiology outbreaks accounting for 177 outbreaks, followed by respiratory disease outbreak (94) and foodborne disease outbreaks (25).


In Slovenia, the number of educational institutions included in the Eco school program constantly grows. 722 institutions registered as an eco-school in the school year 2018/19. This present 35 % of all schools, including kindergartens in Slovenia. Thus, more than 130,000 children and 8,500 teachers were engaged in the environmental projects as part of the environmental education. Internationally, the eco-school program includes more than 50,000 institutions of which 17,000 already signed for a green flag.
