Comparison of periods 1961–1990 and 1991–2020 on the chosen representative stations around Slovenia shows decrease of heating degree days by around 10 % and multiple increase of cooling degree days. With projected continuous temperature raise until the end of 21st century, those trends are expected to continue. Thus, in Slovenia, energy demand for cooling will increase in the warmer period of the year, while the energy demand for heating will decrease in colder period of the year. Same trend is projected for Europe in general.

Among the statistical regions of Slovenia, the Osrednjeslovenska region has the highest ecological footprint per capita (5.8 gha), while the Goriška region has the lowest (4.79 gha). The largest share of the ecological footprint in all regions is represented by the carbon footprint, contributing approximately 60%. A significant portion is also attributed to forest products (around 20%) and agricultural land (around 10%). The region with the highest biocapacity per capita is Primorsko-notranjska (8.02 gha), while Osrednjeslovenska has the lowest (1.11 gha).

Annual growing season length is increasing almost everywhere in Europe, mostly in Eastern and Northern part. In Slovenia, the length of the annual growing season is increasing, especially since mid-1990s. According to projections, the duration of the annual growing season throughout Europe will increase in future.

Net greenhouse gas (GHG) emissions in the land use, land use change, and forestry (LULUCF) sector amounted to -4.291 kt CO₂ eq. in 2023. In this year, net sinks were 1.7% higher compared to the previous year and 40% lower compared to 2005. According to the Slovenian Forest Service, felling in 2024 was 7% higher than in 2023. In 2024, the share of sanitary felling was around 45% of the total annual felling, which means that it has increased slightly again.

GHG emissions in industry decreased by 7,1% in 2023 compared to the previous year. Since 2019, a trend of decreasing GHG emissions has been observed in this sector, mainly due to the reduction of GHG emissions in the ETS subsector of the industry sector.
