In 2022, the number of employees in the environmental goods and services sector increased by 4.2%. The share of employees in this sector in relation to all employees in Slovenia has not changed much in recent years. Slovenia's goal is to increase the number of green jobs, the target value has, however, not been set. In order to compare the situation in Slovenia with that in the EU, changes compared to the previous year are monitored.

The implicit tax rate on energy in Slovenia amounted to 247 €/toe in 2023, which is 4% higher than in the previous year but still 17% lower than in 2016, when it reached its peak for the period 2012–2023. Compared with the EU-27, it was 3.6% above the EU average in 2023, while it was below the European average only in the years 2020–2022 due to temporary crisis-related measures. In addition to tax policy, the rate is also influenced by changes in the structure of energy consumption and energy efficiency.

In 2023, energy efficient district heating (DH) systems, i.e. systems that meet one of the criteria defined in Article 50 of the Act on Energy Efficiency, produced 87,7% of all heat in DO systems, which is the highest value in the observed period. The total share of heat from renewable energy sources (RES) and waste heat amounted to 21,2% in 2023. It increased by 0.5 percentage points compared to the previous year, and by 5.5 percentage points compared to 2016.

According to the data for 2023, GHG emissions per unit of electricity produced amounted to 166 gCO₂/kWh. In the period 1992–2023, the intensity of GHG emissions decreased by 62,4%. Compared to the EU-27 average, intensity of GHG emissions in Slovenia in 2023 was 19,8% lower.

In 2023, 65% of the population was connected to municipal wastewater treatment systems with secondary or tertiary treatment, which do not produce GHG emissions. Compared to the previous year, the share increased slightly, and compared to 2017, it rose by 3.5 percentage points.
