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.

Although a quarter of the newly registered personal cars in Slovenia are electric or hybrid, their share among all personal vehicles is only around 3%. This is due to the fact that households rarely decide to purchase new cars, resulting in a high average age of cars over 10 years, and it will take a long time for our vehicle fleet to become less energy-intensive. Slovenia ranks in the bottom quarter of European countries by the share of first registrations of new personal electric vehicles.

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.

The trend of decreasing energy consumption in households between 2010 and 2022 indicates a positive attitude of the population towards efficient energy use. However, since 2017, a negative trend has been observed, particularly in households' awareness of their own energy consumption and in their consideration of more efficient use. With three-quarters of households in 2022 rating their energy consumption as medium to very high, a significant potential for reducing energy consumption in this sector is suggested.
