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.

Over the period 2012-2022, some energy prices increased and some decreased (in constant 2012 prices). Over the same period, the price of electricity for typical industrial consumers increased the most, by 64.4% in real terms, followed by the price of natural gas for industrial consumers, by 5.1%, and the price of fuel oil, by 3.5%. The price of natural gas for typical household consumers decreased the most, by 20.3%, followed by petrol, by 17%, then electricity for households, by 10.7%, and lastly diesel, by 1.7%.

Although the annual number of road traffic fatalities in Slovenia has been declining for decades and has decreased to about a third since independence, traffic still requires an excessive tax. The number of traffic accidents with victims or serious injuries is at the level of 30 years ago, the number of serious injuries is already 15 years stagnant. Traffic accidents have claimed an average of almost 110 lives per year over the last ten years, and fortunately, the number of deaths in traffic accidents has been slightly decreasing over the past ten years.

Soil erosion is a natural geomorphic process of soil particle detachment and transport. Due to human activities, it can be significantly accelerated, reaching levels much higher than in natural conditions. Erosion (water, wind, and tillage erosion) remains the most significant threat to soils in many regions of the world. Measuring erosion is typically done under controlled conditions on standardized test plots, which is a time-consuming, costly, and organizationally demanding process. Therefore, erosion risks and intensities are often assessed using computational models.

Fuel prices could play an important role in the internalization of external transport costs, but this potential is not exploited in Slovenia. Determining the price of fuels has primarily an economic function and is not a tool of environmental policy. Fuel taxation is a function of the country's economic policy and responds to crude oil prices on the international market, which is a reflection of global supply and demand and geopolitical (in)stability.
