In Slovenia, the number of companies registered under ISO 14001 and EMAS schemes, as well as the number of awarded EU Ecolabels, is gradually increasing. In the year 2021, the number of ISO 14001 certificates significantly increased (by 63), while in 2022, there was a rise in environmental EU Ecolabel (by 15). In terms of the number of awarded ISO 14001 certificates and EU Ecolabels per million inhabitants, Slovenia ranks above the EU-27 average on a European scale. However, its performance is slightly weaker in the field of EMAS, where Slovenia falls below the EU-27 average.

Air pollution with PM₁₀ was the lowest in 2021 since we have been carrying out measurements. For the first time, at no monitoring site did the sum of exceeding the daily limit value for PM₁₀ (50 µg/m³) exceed the number of 35, which is allowed for the whole year. Even the annual limit value for PM₁₀ in 2021 was not exceeded at any monitoring site.

Between 1980 and 2021, extreme events related to climate change in EU-27 resulted in an economic loss of EUR 560 billion, of which EUR 56.6 billion from 2021. Climate extremes are becoming more common. Without further action, even greater economic damage is expected in the future. This trend is also noticeable in Slovenia. The difference between the period 1980-2015 and 1980-2021 is as much as € 2,38 billion. In comparison to the previous period 1980-2020, the difference is € 1,01 billion.

In 2021, the levels of benzo(a)pyrene at all urban monitoring sites reached the target value. Annual trends of benzo(a)pyrene levels show that the highest levels are measured during the heating season. In summer, levels are significantly lower at all locations.

The rate of defoliation and forest decline in Slovenia was relatively stable until 2020, with a slightly negative trend. After 2020, a deterioration of tree defoliation was observed.
