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.

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.

The large majority of organisations from the public and service sector believe that they are ecologically conscious and that they separate waste. The majority of organisations responded that the efficient use of energy in their business premises is important due to both reducing the costs and to protect the environment. Three quarters of companies and two thirds of public administration organisations have stated that they are well familiar with the environmental impact of their business premises.

The analysis of results of the Energy Efficiency Survey of Slovenia for the public and service sector (REUS JSS 2020) indicates that less than a tenth of organisations from the public sector and less than a fifth of office-based companies from the service sector (e.g. banks, post offices and other administrative and office premises) believe that energy consumption in their business premises is either low or very low.

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.
