The share of renewable energy sources (RES) in the use of fuels in industry amounted to 11% in 2021, which was 0.7 percentage point behind the annual indicative target value. The 2021 indicative target was thus not achieved. In order to achieve the target of 30% of RES in the use of fuels in industry in 2030, the share of RES will have to increase by 19 percentage points or by about approximately 2 percentage points per year.

In 2021, 62% of the population was connected to the municipal wastewater treatment systems with secondary or tertiary treatment, which do not produce GHG emissions. Compared to the previous year, the share decreased by a small percentage point, moreover, the share has remained almost unchanged since 2017.

The performance of EU countries in the field of eco-innovations is monitored by a composite index that includes 12 indicators from five thematic areas. Slovenia is ranked as an average eco-innovation performer. The values of the indicator are gradually improving and show the progress of the eco-innovation index, but they still remain below the EU average. The target value for Slovenia has not been set.

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.

Regarding the forest area, deforestation accounts for an insignificant share. The average of the last ten years is approximately 405 ha (350–550 ha per year) and thus does not represent a significant factor in forest cover changes. Until 2008, most deforestation is a result of infrastructure facilities construction. In 2008, the unprecedented increase in deforestation for agricultural purposes occurred. The increase was due to the amendment to the Forest Act, which subject to the conditions allows the issuance of an authorisation for deforestation for agricultural purposes up to 0.5 ha.
