The implicit energy tax rate fluctuates throughout the entire observed period, but recently it has been gradually declining. In 2021, the value of the indicator for Slovenia was 7% lower than the EU-27 average. Before 2009, when it increased significantly, it was notably lower than the EU average. The reasons for the differences can be found mainly in the differences in the structure of energy use, where the share of liquid fuels for motor vehicles is significantly higher in Slovenia, and in the taxation levels of individual energy sources.

The emission productivity in Slovenia improved in 2021 and amounted to 2,79 EUR₂₀₁₀/kg CO₂ ekv. Despite the progress made in recent years, is, however, the progress in emission productivity in Slovenia when compared to the European Union (EU), still relatively slow, thus there is a need to further strengthen the connection between economic development and measures for reducing GHG emissions.

In 2016 and 2017, the trend of reducing specific emissions of new vehicles has stopped, and in 2018 and 2019 they have even increased. After a 10% reduction in 2020, the specific emissions of new vehicles remained almost unchanged in 2021, falling short of the target set for that year. In 2022, the specific emissions of new vehicles decreased again, by 6%.

In 2021, for the first time since 2016, the average emissions of all vehicles increased slightly in comparison to the previous year. Target values have not been achieved.

After 2005, the gross nitrogen budget ranged between 32 and 69 kg per hectare of agricultural land with an indistinct downward trend. On average over the last five-year period, the target value (less than 50.4 kg per ha) was achieved. In 2022, the nitrogen balance surplus rose sharply compared to the previous year (from 46.2 to 69.1 kg per ha). The target value (less than 49.4 kg per ha) was therefore not achieved. The increase in the surplus is attributed to the drought, which caused a decrease in the nitrogen uptake by agricultural plants.

Areas of fields and gardens in measures that require fertilization based on rapid soil or plant tests have significantly exceeded the target value set by the 2014–2020 Rural Development Programme.
