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.

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%.

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.

In Slovenia, the average Corg stocks in the treated agricultural lands (KZ) to a depth of 30 cm was 92.9 t/ha, with the highest in the soils of marsh meadows – 197.0 t/ha. In soils with extensive use, including extensive orchards (ES), permanent grasslands (TR), land undergoing afforestation (ZR), and KZ overgrown with trees and shrubs (DG), Corg stocks ranged from 92.2 to 109.4 t/ha. Corg stocks in vineyard soils (VI), intensive orchards (IS), and arable lands (NJ) ranged from 60.0 to 92.7 t/ha.
