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.

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).

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.

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.

While the declarative attitude of Slovenian households towards the environment and efficient use of energy is improving, the ratio between environmentally aware and unaware households remains unchanged. This is evident from their environmentally oriented behaviour and actual efficiency in energy use. The results of the Slovenian Energy Efficiency Survey – REUS indicate a great potential for reducing final energy consumption in households through the development of environmentally oriented behaviour and positive habits in energy use.
