Temperature in Slovenia is increasing faster than global average. Increase in the annual average temperature is most evident in the last three decades. Warming of the atmosphere will continue according to the climate change projections. The result of warming is an increase in sea level (due to melting of glaciers and thermal expansion), increase in level of the greenhouse gases in the atmosphere (contributes to warming), and many extreme weather and climate events (like floods, droughts, hail and heavy wind), which will influence the quality of our lives.

Comparison of periods 1961-1990 and 1991-2020 on the chosen representative stations around Slovenia shows decrease of heating degree days by around 10 % and multiple increase of cooling degree days. With projected continuous temperature raise until the end of 21st century, those trends are expected to continue. Thus, in Slovenia, energy demand for cooling will increase in the warmer period of the year, while the energy demand for heating will decrease in colder period of the year. Same trend is projected for Europe in general.

Annual growing season length is increasing almost everywhere in Europe, mostly in Eastern and Northern part. In Slovenia, the length of the annual growing season is increasing, especially since mid-1990s. According to projections, the duration of the annual growing season throughout Europe will increase in future.

In Slovenia, the number of educational institutions participating in the Eco-Schools program is constantly growing. In the school year 2022/23, a total of 732 institutions were involved in the program, which represents nearly 38% of all schools and kindergartens in Slovenia. Through environmental projects, over 130,000 Slovenian children and students, as well as 8,500 educators and teachers, were included in the environmental education system.

The Slovenian economy is characterized by a high share of industry in the total created added value (25.7%, year 2022). Agriculture, forestry and fishing had the lowest share among all activities (1.9%, year 2022). Slovenia has below-average shares of gross value added in all tertiary and quaternary activities (with the exception of trade, hospitality, and transportation) compared to the EU. Data on the index of added value by activity show that information and communication technologies experienced the highest growth compared to 2015 (index = 151, year 2022).
