In Slovenia, built-up areas continue to increase, representing 5.7% of the land use structure in 2023. In the period 2019-2023 built-up areas were predominantly spread to grasslands (42%), forest (18.6%) and the category other (16.1%), with the total built-up area increasing by 1,618.9 ha over this period. Existing data sources in Slovenia have recently made it possible to evaluate the actual loss of land to development.

The intensity of final energy consumption as well as sectoral intensities in Slovenia have decreased over the period 2005-2022. Most in industry, least in transport. Comparison with the EU-27 shows that Slovenia is worse than the EU-27 average, but the gap has almost halved over the period 2005-2021, with contribution of all sectors except transport.

The intensity of SO2, NOx and CO2 emissions from electricity and heat production in public thermal power plants in 2021 was significantly lower than in 2005, with SO2 emissions intensity 94% lower, NOx  71% lower and CO2 28% lower. Compared to the EU-27 average, the intensity of CO2 emissions in Slovenia in 2021 was higher, NOx emissions slightly lower and SO2 emissions significantly lower.

Over the period 1990-2022, the amount of spent nuclear fuel, the only high-level radioactive waste, increased at an average rate of 5% per year. In the absence of a satisfactory permanent storage solution, there are concerns about the accumulation of this waste.

Overall, taxes on energy products have alternated between decreasing and increasing over the period 2012-2022 (expressed in constant 2012 prices). With the exception of electricity for typical household consumers, where levies have been increasing over the period 2012-2016, taxation on other energy products has been gradually decreasing. Energy taxes were lower in 2022 compared to 2012. The only exception is the electricity tax for typical industrial consumers, where the direct tax burden increased mainly at the expense of contributions (EE, RES+CHP, CO2 tax).
