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 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.

F-gas emissions from leaks from stationary installations increased significantly in 2022 due to a significantly higher use of refilled refrigerants. This represented a significant deviation from the indicative target for reducing emissions from the use of F-gases under the EU F-gases Regulation. Compared to 2015, F-gas emissions from leaks were 17% lower in 2022, while, according to the F-gases Regulation, they should have been lower by 55%.

In 2021, the amount of incentives for the implementation of measures related to energy efficiency (EE) and renewable energy sources (RES) in non-ETS industry amounted to EUR 4.1 million, i.e. 30 % less than the previous year. In 2022, according to currently available data, the amount was further reduced to EUR 1.1 million.
