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.

Energy efficiency in industry has improved significantly over the period 2005–2022, with a 39% increase. The sectors that have contributed the most to this were production of paper, machinery and equipment, chemical industry and production of non-ferrous metals, while the production of steel and non-metallic mineral products have contributed the least.

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.

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.

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.
