The amount of waste from coal combustion is decreasing as a result of the reduction in the use of coal for electricity generation. In 2022, the amount was 15% lower than the previous year. By far the largest source is the Šoštanj thermal power plant. Most of the waste is used as fill material in mines.

Measurements of soil samples from different agricultural land uses over the period 2015-2023 show that phosphorus (P) is deficient in soils of extensive orchards, olive groves and pastures, below optimum in intensive orchards, vineyards and grasslands, and adequate in arable land. The low phosphorus content is mainly due to the natural low content of this nutrient in Slovenian soils and leaching. Potassium (K) contents are generally higher than P, reflecting Slovenia's better natural soil K supply.

The intensity of GHG emissions from fuels and energy in transport in Slovenia was 4.7% lower than the baseline in 2021, which is 1.3 percentage points below the target reduction. Although the intensity is decreasing, the pace is too slow. The largest contribution to reducing intensity comes from the blending of biofuels. In the EU, the largest reductions were achieved by Sweden and Finland, along with 11 other countries that achieved reductions of 6% or more.

It is estimated that in 2021, over €396 million in energy subsidies was allocated in Slovenia (or 356 € million when adjusted to constant prices in 2015). Incentives for environmentally harmful energy production from fossil fuels and the use of fossil fuels represented 26% of all energy subsidies in 2021, whereas this share was as high as 51% in 2015. Significant progress is observed in subsidizing production from renewable energy sources, CHP, and energy efficiency measures.

In Slovenia, the breeding of indigenous domestic animals is becoming less attractive, and out of 15 indigenous breed 14 are endangered. The Carniolan honey bee being the only exception. Eleven out of 13 traditional breeds are also endangered. The share of introduced animal breeds and cross-breeds with introduced breeds has been increasing. The breeds and races where the adaptation to natural conditions is the strongest are the most successful with defying the introduced breeds.
