Greenhouse gas (GHG) emissions from transport in Slovenia almost tripled between 1986 and 2022. In the EU, GHG emissions from transport also exceed economic growth on average, but significantly less than in Slovenia; in the period 1990-2022, they increased by a quarter in the EU-28. The main source of GHG is mostly road transport, which contributes as much as 99% of all GHG emissions from transport. The majority share of traffic emissions in Slovenia in total GHG emissions and insufficiently effective measures to reduce them hinder Slovenia's efforts to achieve the accepted obligations.

The ownership of passenger cars, closely linked to their usage, has been steadily increasing in Slovenia for a long time – it has doubled since the country's independence in 1991. Between 2008 and 2015, car ownership grew more slowly due to the economic recession, but since 2015, the growth has accelerated again. The exceptions were the pandemic years of 2020 and 2021. Slovenia's motorization rate (measured in the number of personal cars per thousand inhabitants) exceeds the EU average and is higher than that of many economically more developed EU countries.

The proportion of WEEE disposed of within mixed municipal waste is decreasing, while the proportion of WBA disposed of within mixed municipal waste is very low and does not change significantly over the years. On the other hand, the amount of separately collected WEEE is increasing. Almost 15,500 tons of WEEE were collected separately in Slovenia in 2022, which is 7% more than in 2019.

The indicator mainly shows the unidentifiable direction of development. The majority of data were available only for a limited period, and therefore, reliable estimation of trends is not possible. Cereals are the predominant group of crops in Slovenia. Areas for growing green fodder crops and industrial plants are increasing, while the production of root and tuber crops has stabilized on two percent of arable land. A slow diversification of crop types is noticeable, with a positive trend in the share of legumes, although this share has stabilized at around 15% in recent years.

In Slovenia, emissions of persistent organic pollutants (polychlorinated biphenyl, polycyclic aromatic hydrocarbons, hexachlorobenzene, dioxins and furans) decreased between 1990-2022, primarily due to targeted legislation, improved control and use of best available technologies.
