Environmental protection is important to the residents of the EU and Slovenia. The most significant environmental issues mentioned are growing amount of waste, air pollution, and climate change. A large majority of respondents agreed with statements expressing concern about various environmental problems and acknowledging their impact on their daily lives and health.

Asthma is the most common chronic disease among children and one of the major causes of hospitalization to the age of fifteen. In 2019, in EU countries, the share of people reporting asthma was 5,7 %, and for Slovenia it was 4,8 %.  In the period 2017-2021, the municipalities of Kostel, Kobilje and Cankova stood out in terms of the number of hospitalizations for asthma. Recent evidences support relationship between exposure to air pollution and exacerbation of asthma, mainly due to exposure to particulate matter (PM₁₀).

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.

The frequency of agricultural drought in Slovenia has been increasing in recent decades. In the last twenty years, we have recorded 7 droughts that affected Slovenia at the scale of a natural disaster. Drought is occurring with increasing intensity and in areas and seasons where there have been no problems in the past. An additional risk for agricultural drought are rapidly developing droughts in summer ("flash droughts"), which occur especially during heat waves. Projections show that trend of increasing frequency and intensity of agricultural drought will continue in the future.

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.
