In Slovenia, just over 1.1 million tonnes of municipal waste were generated in 2023, which is 7 % more than the previous year, of which 69 % was collected separately. 26 % of municipal waste generated was packaging waste. In 2023, more than 294.000 tonnes of packaging waste were generated in Slovenia, of which more than one fifth was plastic packaging waste.

In recent years, the number of sampling sites where individual pesticides exceed the quality standard has been decreasing. The concentration of pesticides in groundwater is also declining. However, in areas of Slovenia characterized by intensive agricultural activity, some pesticides still exceed the quality standard.

The share of waste electrical and electronic equipment (WEEE) disposed of within mixed municipal waste annually in the period 2020-2023 represented an average of 0.8% of collected mixed municipal waste. The share of waste batteries and accumulators (WBAs) was even lower, representing an average of 0.03% of all collected mixed municipal waste in the same period annually. The amount of separately collected WEEE has been increasing over the years. In Slovenia, just over 16,600 tonnes of WEEE were collected separately in 2023, which is almost 8% more than in 2022.

The average occupancy rate of cars in Slovenia is declining. In heavy goods transport, average occupancy is increasing as a result of the growing share of tractor units in freight transport, which have a higher load capacity. The NEPN emphasizes the importance of increasing vehicle occupancy – e.g., by promoting carpooling, developing appropriate infrastructure, and organizing freight transport more efficiently—as an important contribution to reducing GHG emissions and energy consumption, while governing transport demand and shifting to more sustainable forms of transport.

Incentives that go against the goal of reducing greenhouse gas (GHG) emissions have increased again after 2021, primarily due to extensive emergency measures introduced in response to rising energy prices. Excluding these temporary measures, the level of such subsidies in 2023 did not change significantly compared to 2020, with their value increasing by approximately 5.7%.
