The implicit tax rate on energy in Slovenia amounted to 250 €/toe in 2024, which is 1% higher than in the previous year but still 15% lower than in 2016, when it reached its peak in the 2012–2024 period. Compared to the EU-27, it was 0,7 % above the EU average in 2024, while it was below the European average only in the years 2020–2022 due to temporary crisis-related measures. In addition to the tax policy, the rate is also influenced by changes in the structure of energy consumption and energy efficiency.

In 2024, 67% of the population was connected to municipal wastewater treatment systems with secondary or tertiary treatment that cause minimal GHG emissions. Compared to the previous year, the share increased by almost 2 percentage points. Compared to 2017, the share increased by 5.4 percentage points.

In 2025, the leverage of incentives in the public sector amounted to 32.9 euro cents of subsidy for 1 euro of investment, which was 21 euro cents less than in 2024. The decline was due to the projects supported by the Eco Fund under the calls for co-financing new investments in the construction of highly energy-efficient, nearly zero-energy buildings of general public interest. For these projects, the leverage of incentives was only 13.3 euro cents of subsidy for 1 euro of investment, while they accounted for as much as 73% of the total value of supported investments.

According to the projection based on existing measures, total greenhouse gas (GHG) emissions will remain at a level similar to today's until 2030 and will then begin to decline. Under the projection that includes additional measures, however, emissions will decrease dramatically – by 35% by 2030 and by 88% by 2050. The projections indicate that, with the intensive implementation of measures, it is possible to achieve the targets set for reducing total GHG emissions, as well as emissions from sources not covered by the Emissions Trading System (ETS).

Slovenia has a relatively high level of energy intensity, although it has been declining, particularly rapidly in recent years. Between 2005 and 2023, energy intensity decreased at an average annual rate of 3.2%. In 2024, energy intensity increased for the first time since 2016, rising by 2.1%. In 2024, Slovenia’s energy intensity was 37% higher than the EU-27 average, which is 15 percentage points less than in 2005.
