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 average age of passenger cars in Slovenia increased from 6.8 years in 1992 to 9.4 years in 2014. The structure of passenger cars by age changed as well. The number of passenger cars older than 12 years more than doubled in 2015 in comparison to 2001. Also, the share of passenger cars aged less than three years decreased by almost a half during this period. The share of heavy duty vehicles and the share of mopeds and motorcycles older than 12 years has also increased since 2009, while the share of these vehicles under three years of age decreased in the same period.

Bad

The share of present invasive species (eg. Robinia pseudacacia, Ailanthus altissima, Buddleja davidii, Erigeron annuus) in the last decade shows an increasing trend. An increase in the share of invasive species is evident along the great lowland rivers Sava, Mura and Drava, as well as along the Kolpa river. In higher areas of Slovenia, particularly in the Alps and the Dinaric region, invasive species are very few or entirely absent. However, a notable increase in their share along the western border of the Dinaric region raises concerns.

Neutral

The above-average years 2013 and 2014 were followed by average year 2015 and average period 2016 – 2019 of annual runoff. In the year 2020 annual runoff was below-average. In the period 1961 - 2020, the driest years were 2011, 2007, 2003, 1983, and 1971. The long-term downward trend of river runoff from the territory of Slovenian currently persists.

Good

Designated areas, which include Natura 2000 and protected areas, cover 40% of the total area of the country, which is almost six times more than in 1992. The increase in designated areas is due to designation of Natura 2000 network in 2004 and more landscape parks from 2008 until 2019. For any planned construction activity on designated areas a nature conservation consent is needed.

Bad

In the period (2008-2021), the farmland bird index is 76.8, and the grassland bird index in the agricultural landscape is 56.3.The fourteen-year trend of farmland birds shows moderate declining, despite a stable trend over the last eight years.

 

 

Bad

The results of the Energy Efficiency Survey of Slovenia - REUS show that the share of Slovenian households that are ready to start using or increase their use of public transport over the next 12 months remains quite small – a trend has not significantly changed during the 2011-2019 period. The data show that almost a tenth of households are ready, while a quarter of households are considering the option, while more than two thirds are not ready to start using or to increase their use of public transport.
