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, 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.

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%.

GHG emissions in industry decreased slightly in 2021 compared to the previous year. Since 2009, there has been no noticeable trend of decreasing GHG emissions in this sector.

GHG emissions in the ETS subsector of industry sector decreased for the third year in a row and were 4.2% lower than the previous year. GHG emissions in the non-ETS subsector of the industry sector increased by 5.5% in 2021 compared to the previous year. In 2021, the share of emissions from the ETS subsector was 57.4% of all emissions in industry sector, and the share of non-ETS emissions was 42.6%.

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.
