The indicator monitors the economic, social and environmental dimensions of sustainable development by comparing the HDI - the human development index and the ecological footprint. Between 1990 and 2019, the value of the Human Development Index (HDI) increased from 0.774 to 0.917 (by 18.5%). Slovenia is ranked among the countries with a very high human development index, in 22nd place out of 189 countries included in the calculations. In general, the higher the HDI of a country is, the higher the ecological footprint is.

The estimated average long-term intakes of metals (lead, cadmium and mercury) into the human body through food in the adult population of Slovenia do not exceed the reference points (BMDL) or health-based guideline values (tolerable daily/weekly intakes), and in children lead and cadmium on average, similarly to the EU, may be exceeded.

In 2021, the share of RES in transport increased for the fifth consecutive year and amounted to 10.6%. With this, it was 0.3 percentage points behind the non-binding 2021 target from the National Energy and Climate Plan (NECP) for 2021.

Slovenia's import dependence is not decreasing and is about 50%. In 2020 it was exceptionally lower than in previous years due to the epidemiological situation. The most problematic is the import dependency on gaseous fuels, as Slovenia is heavily dependent on fuel imports from Russia.

Species diversity in Slovenia is stil considerably well preserved, distinctly higher in western part of the country. Without systematic monitoring on permanent plots it is impossible to recognize short term trends, but in some regions negative trends are result of landuse changes and impact of alien invasive species.
