In Slovenia, the share of landfilled municipal waste in 2022, based on all generated municipal waste, was 8.8% or slightly more than 90,000 tonnes. Thus the goal of reducing the amount of municipal waste landfilled to 10% or less by weight of all generated municipal waste by 2035 has already been achieved. The waste was landfilled at 9 non-hazardous waste landfills.

Temperature in Slovenia is increasing faster than global average. Increase in the annual average temperature is most evident in the last three decades. Warming of the atmosphere will continue according to the climate change projections. The result of warming is an increase in sea level (due to melting of glaciers and thermal expansion), increase in level of the greenhouse gases in the atmosphere (contributes to warming), and many extreme weather and climate events (like floods, droughts, hail and heavy wind), which will influence the quality of our lives.

In the period 2008–2024, the farmland bird index is 77.1, while the grassland bird index in the agricultural landscape is 58.3. The sixteen-year trend of the farmland bird index shows moderate declining, despite a stable trend over the past ten years.

In 2023, the energy reduction in the energy efficiency obligation scheme (EEOS) and alternative measure, t. i. Eco Fund programs, amounted to 1,445 GWh. A majority of the new savings, 65%, was this time achieved through the implementation of energy efficiency (EE) and renewable energy source (RES) measures within the EEOS, where a large gas-steam unit in a district heating plant was installed. The new savings were more than 200% higher than the target value for 2023.

Final energy consumption amounted to 4,491 ktoe in 2023 and decreased by 5 % compared to the previous year. There was a decrease in all sectors, with the exception of other use. Final energy consumption was 380 ktoe (- 7.8%) lower than the 2023 indicative target value from the National Energy and Climate Plan from 2020 (NECP 2020) and 282 ktoe (- 5.9 %) lower than the value from the National Energy and Climate Plan from 2024 (NECP 2024). The indicative annual target was thus achieved. In the period 2000‒2023, final energy consumption decreased by 1 %.
