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.

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%.

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.

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, 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.
