While the declarative attitude of Slovenian households towards the environment and efficient use of energy is improving, the ratio between environmentally aware and unaware households remains unchanged. This is evident from their environmentally oriented behaviour and actual efficiency in energy use. The results of the Slovenian Energy Efficiency Survey – REUS indicate a great potential for reducing final energy consumption in households through the development of environmentally oriented behaviour and positive habits in energy use.

Phytoplankton biomass, expressed as chlorophyll a concentration, reflects nutrient loading in the marine environment. Chlorophyll a concentrations shows a trend towards improvement in the status of the Slovenian sea, as the ecological status has been assessed as high or good over the last period.

Deadwood is an important animal and plant habitat that contributes to the biodiversity of forest ecosystems. According to Slovenia Forest Service data, the volume of standing and fallen trees without stumps and branches in 2022 was 21.3 m³/ha, which represented approximately 6% of the entire wood stock of forest stands. In virgin forests, however, the deadwood volume can be even several dozen times greater.

In the past centuries, forest area has been increasing constantly after 2010; however, the rate of expansion has slowed down and remains relatively stable in recent years. Since 1875, when forests covered only 36% of the Slovenian territory, forest cover has increased to 58.5% in the year 2009 and rests stable today at 58.0 %. In terms of forest share, Slovenia ranks third among EU-28 countries, behind Sweden and Finland.

In Slovenia, forests have been growing in terms of growing stock and increment for decades. They have increased by more than 140% over the last 70 years. In addition to natural conditions, harvesting depends on socioeconomic factors, and recently on the occurrence of natural disasters (windbreaks, icebreakers) and bark beetles outbreaks. By 2014, the felling accounted for about 50% of the increment. After the ice storm in 2014, it increased substantially and accounted for 60 to 75% of the total increment of conifers and deciduous trees.
