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 amount of packaging waste has stabilized in recent years at about 100 kg per capita per year. In 2014, every resident of Slovenia produced 102 kg of packaging waste, which is a few kilos more than in the four preceeding years.

Recovery of packaging waste has been increasing and in 2014 stood at 88%. Recycling is also increasing and in 2014 it reached 70%. Slovenia has reached the EU target – to reuse at least 55% of all packaging materials by the end of 2012.


Data for the period 2010-2019 show a positive trend in the estimated final energy consumption in households. The share of households that estimated their energy consumption as low or very low increased by 8 percentage points from 2010 to 2019. From 2011 to 2019, the share of households considering more efficient energy consumption also increased. The indicator also shows a significant potential for reductions in final energy consumption in households – less than three quarters of households estimated energy consumption in their home in 2019 as moderate, or high to very high.


In 2020, Slovenia recorded a slight increase in the number and total area of functionally depreciated areas (FDAs): 1,132 FDAs were recorded in the total area of 3,695.3 ha. Compared to 2017, their number increased by 51, with a total area of 272.5 ha.

We can notice positive trends towards the revitalization of FDAs, as new activity has taken off on 108 locations, on the 292 FDAs there have been major changes in recent years, where many remediation and renewal processes began, while else ware the physical condition and degradation of the area has deteriorated.


Water consumption in Slovenia represents a relatively small proportion of the annual gross water outflow from the country. In 2018, the annual WEI+ index was around 3%, or, compared to the periodic average of water availability. The Long-term Annual Average Water Exploitation Index shows a slight decrease, but the trend is not statistically significant.


In recent years, the amount of wastewater treated by secondary or tertiary treatment processes increased, while primary treatment processes have closed. The amount of wastewater treated through secondary treatment processes increased by 118 % since 2002 or from 38 million m3 (in 2002) to almoust 46 million m3 (in 2018). There were almost no tertiary wastewater treatment processes in Slovenia in 2002, and in 2018, 72% of wastewater or 116 million m3 of wastewater was treated by tertiary process.


After twelve years (2008-2019) the farmland bird index is 77.3 and the grassland bird index 62.6. The twelve year trend of farmland birds is moderate decline (the subgroup grassland birds have the same trend) in spite of the short-hand stabilisation in the last five years.
