The amount of landfilled biodegradable waste decreased rapidly up to 2013, after which the reduction stopped. In 2016 and 2017, as a result of upgrading the infrastructure for mechanical biological treatment of waste before disposal, the amount decreased significantly again, and in 2018‒2020 it was almost zero. In the period 2016–2020 the amount was significantly lower than the target in 2020. The main measures to achieve this reduction are separate collection of waste and mechanical biological treatment of mixed municipal waste.

In 2020, specific CO₂ emissions in the residential sector amounted to 9.2 kg CO₂ eq/m² or 3% more than the previous year and were 0.4 percentage points below the annual target,. The 2020 target was thus not achieved. The increase was mainly due to the increase of CO₂ emissions from the use of fuels in this sector by almost 4%. The increase was caused on one hand by the colder year, and on the other hand by the coronavirus pandemic and the implementation of measures for preventing the spread of the SARS-CoV-2 virus.

After the increase in number of total passenger kilometres in public passenger transport in 2019, in 2020 the number of total passenger kilometres in PPT sharply decreased. Passenger kilometres decreased to the lowest level in the observed period in both rail transport and road public passenger transport. The main reason for such decrease in passenger kilometres is the large reduction in transport activity as a result of the measures taken during the COVID-19 epidemic.

In accordance with the set targets, it is necessary to ensure faster growth of rail freight transport in comparison to road freight transport. This was not achieved in 2020. The share of rail freight transport in total freight transport with goods loaded or unloaded in Slovenia remained under the projection value of the indicator for 2020. The number of tonne-kilometres in road transport increased by 19,2% in the period 2011−2020. In the same period, the number of tonne-kilometres achieved in rail transport increased by only 13%.

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.
