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.

The large majority of organisations from the public sector and office-based companies (e.g. banks, post offices and other administrative and office premises) believe that increased energy efficiency of business premises is very important. About three quarters of organisations in both sectors think about using the energy more efficiently. For about a third of organisations from both sectors, which think about the efficient energy consumption, its main purpose is to decrease the quantity of energy used in their business premises.
