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.

Tourism in Slovenia is growing steadily. It was particularly high in the last five years before the pandemic, when Slovenia established itself as an attractive green destination. In 2021 and 2022, domestic guest arrivals and overnight stays increased due to the pandemic. In 2024, Slovenian tourism already exceeded the global and European average with an 8% increase in foreign arrivals compared to 2019.

In 2024, we began reporting on the chemical status of groundwater for a longer six-year period, in line with the reporting cycle under the Water Framework Directive. Based on this assessment, the state adopts measures to improve water quality.

Groundwater in intergranular aquifers in Slovenia is most affected by nitrate pollution, particularly in northeastern Slovenia. In contrast, groundwater in karst and fissured aquifers is less impacted due to geographical conditions, lower population density, and a smaller proportion of agricultural land.

For the period 2019–2024, poor chemical status was identified in the water bodies of the Savinja, Drava, and Mura basins. The main cause of poor chemical status in all water bodies was nitrate, with atrazine additionally contributing in the Drava basin.
