During the period from 2012 to 2022, taxes on energy sources in Slovenia fluctuated, generally decreasing except for electricity for industrial consumers, where they increased due to levies. Between 2020 and 2022, temporary measures were introduced to reduce taxes on certain energy sources due to the COVID-19 pandemic and the war in Ukraine. Compared to the EU-27, the taxation of electricity and natural gas for households in Slovenia was lower, while it was higher for industrial consumers; diesel fuel taxation was higher, while gasoline taxation was 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.

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.

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.

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.
