In Slovenia and in other European countries the proportion of vehicle fleet that comply with the latest and most stringent emission standards increased sharply in period 2011-2020. Penetration of new technology is highest for the diesel cars.

One of the main sources of greenhouse gas emissions in Slovenia is road traffic, as passenger vehicles contribute as much as 20 % of all greenhouse gas emissions. It is estimated that, due to the smaller role of public passenger transport in Slovenia, it is necessary to achieve as much as 2/3 reduction of GHG emissions by electrifying the vehicle fleet, which dictates the replacement of existing vehicles with fossil fuels. with electric vehicles (battery and plug-in hybrids EV).

Slovenia has participated in the European Mobility Week (EMW) initiative from the very beginning. Its implementation has become an important form of promotion and encouragement of sustainable mobility planning in the last decade. Since the beginning of the implementation in 2002 136 Slovenian municipalities have participated in the EMW initiative at least once, and 7 municipalities every year. The number of participating municipalities has increased over the years and has already reached almost half of Slovenian municipalities.

The number of inhabitants who live in the impact area of major roads outside urban areas has decreased. In 2017, around 16,000 fewer inhabitants were exposed to high noise levels throughout the day and during the night compared to 2012. In urban areas, the number of inhabitants who are exposed to road traffic noise has not decreased. The number of inhabitants who are exposed to high noise levels throughout the day has remained at the same level as in 2012 and is estimated at 64,000.

The number of inhabitants who are exposed to traffic noise along major roads outside urban areas is gradually decreasing. In 2017, around 16,000 fewer inhabitants were exposed to high road traffic noise levels throughout the day compared to 2012. There is an important difference between inhabitants who live in the impact area of major motorways and highways, and inhabitants who live in the impact area of major main and regional roads.

The number of inhabitants who live in the impact area of major railways outside urban areas and are exposed to rail traffic noise has not changed significantly in the past years. In 2017, around 7,000 inhabitants were exposed to high noise levels throughout the day and around 10,700 inhabitants during the night. Between 2012 and 2017, the number of inhabitants who are exposed to high rail traffic noise did not decrease.

The quantity of end-of-life tyres collected for recovery increased dramatically when producer liability was introduced. Arround 16,000 tonnes of end-of-life tyres is produced, which is about 8kg per capita. In 2015, 65% of end-of-life-tyres have been recovered through material recovery and 35% through energy recovery.

The car remains the primary mode of transportation, regardless of the distance or purpose of the trip, while the use of public transport does not show a significant increase. The main barriers to using public transport are poor accessibility, inadequate timetables, a lack of connections, and difficult access. Time inefficiency is also a significant issue. However, there are reasons for optimism, as households are increasingly open to using public transport and car-sharing.

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.

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.
