Net greenhouse gas (GHG) emissions in the LULUCF sector amounted to -4.452 kt CO₂ eq in 2024, indicating that the sector was a net sink. Compared with 2005, the size of the net sink was 41% lower, mainly due to the impacts of natural disturbances in forests and increased harvesting levels over the past decade. According to the Slovenian Forest Service, timber harvesting in 2025 decreased by approximately 13% compared to 2024, while the share of sanitary fellings remained high, accounting for around 32% of total recorded harvesting.

In 2024, the share of RES in transport, after an increase in 2023, dropped again and amounted to 9,2%. With this, it was 1,6 percentage points behind the non-binding 2024 target from the updated National Energy and Climate Plan (NECP 2024).

Specific CO₂ emissions from new passenger cars amounted to 127 g CO₂/km in 2024 and decreased to 117 g CO₂/km in 2025. The increase in the share of electric passenger cars contributed significantly to this reduction. Nevertheless, the target value for the 2025–2029 period, set at 93.6 g CO₂/km, has not yet been achieved.

In 2024, average CO₂ emissions from all passenger cars amounted to 157.5 g CO₂/km and changed only marginally compared with 2023. The target value for 2020, set at 152 g CO₂/km, therefore remained unmet.

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).

In 2024, greenhouse gas (GHG) emissions from sources covered by Regulation (EU) 2023/857 increased by 1.8% compared to the previous year. Nevertheless, they remained 0.4% (41 kt CO₂ eq) below the annual target set under the Regulation. The National Energy and Climate Plan from 2024 (NECP 2024) sets a more ambitious 2030 target for reducing non-ETS emissions than the EU Regulation. A comparison with the indicative trajectory towards this target, starting in 2021, shows that emissions were 5 percentage points above the trajectory in 2024.
