The export of waste from Slovenia decreased in 2020, for the first time after ten years of growth. We exported around 340 thousand tonnes of waste, mainly to Austria and Hungary. The import of waste also declined for the first time in 2020, we imported around 61 thousand tonnes of waste.

The results of the Slovenian Energy Efficiency Survey (REUS) 2019 show that over three quarters of all households decrease their greenhouse gas emissions by walking short distances, about half of them travel by bike, 1 in 7 uses public transport and 1 in 8  uses car sharing. Seven out of ten households were willing to combine their personal vehicle with other forms of transportation in their daily travel.

In Slovenian larger cities, in 2021, 35% of children (0-14 years old) in larger cities were exposed to concentrations of 0-20 µg PM₁₀/m³ and 65% of children (0-14 years) in larger cities were exposed to concentrations of 20-30 µg PM₁₀/m³. In Europe, most children live in an environment where PM₁₀ concentrations are below 26 µg/m³.

Domestic material consumption amounted to almost 28 million tonnes (13,1 million tonnes per capita) in 2020 and was 2,6% lower than in 2019. The amount of biomass utilized decreased by 1,5% compared to 2019, also  the amount of mineral resources exploitation by 1,5%. The amount of used fossil energy  increased by 1,5% compared to 2019. In 2020, the import to Slovenia was 3,3 million tonnes higher than the export from Slovenia.

The amount of landfilled biodegradable waste decreased rapidly up to 2013, after which the reduction stopped. In 2016 and 2017, as a result of upgrading the infrastructure for mechanical biological treatment of waste before disposal, the amount decreased significantly again, and in 2018‒2020 it was almost zero. In the period 2016–2020 the amount was significantly lower than the target in 2020. The main measures to achieve this reduction are separate collection of waste and mechanical biological treatment of mixed municipal waste.
