Since 2012, the installed capacity of the systems for the production of electricity from RES has increased by 47.3%. More than half of this increase, 24.7%, was achieved in the last three years. The indicator is currently on a trajectory of achieving the indicative targets until 2030 set in the National Energy and Climate Plan (NECP).

According to the first estimates for 2022, GHG emissions per unit of electricity produced amounted to 208 gCO₂/kWh. In the period 1992–2022, the intensity of GHG emissions decreased by 52.8%. Compared to the EU-27 average, it was in Slovenia in 2022 17.1% lower.

In 2021, greenhouse gas (GHG) emissions from sources according to the Regulation (EU) 2023/857 increased by 5.5% compared to the previous year and were lower than the annual target by 8.6%, which means that the target was achieved. GHG emissions decreased in the waste and electricity and heat production sectors, and the most in the consumer sector. In all other sectors emissions increased, with the exception of the agriculture, where they remained at the 2020 level.

Frequency of groundwater drought is increasing in recent decades in alluvial aquifers. 8 out of 10 years with highest intensity of groundwater drought in period 1981-2023 occurred after year 2000. Groundwater droughts with higher intensity is characteristic for winter while milder groundwater droughts mostly occur at the beginning of autumn. Groundwater drought intensity is also increasing seasonally with time between June and September when groundwater use is pronounced.

The vast majority of registered personal vehicles are still powered by conventional fuels (petrol and diesel). The proportion of vehicles with alternative propulsion systems has doubled from 2019 to 2022, yet it remains very small.
