Plans to improve air quality in Slovenia include a number of measures. It is crucial that the state ensures the financing of measures and thus the implementation of measures, and consequently the improvement of ambient air quality. In 2019, as much as EUR 15.56 million more investments were paid out than in 2014. In the period from 2014 to 2019, most investments were in wood biomass boilers, followed by investments in heat pumps.

The total renewable amount of groundwater in shallow aquifers in Slovenia in the hydrological year 2019 was below the average of the comparative hydrological water balance period 1981-2010.

Energy consumption in transport has been declining slightly in recent years. This is due to combination of lower domestic vehicle consumption as well as lower sales to foreign vehicles. Most of the energy is used in road transport. Consumption of diesel fuel in road transport is increasing.

Water consumption in Slovenia represents a relatively small proportion of the annual gross water outflow from the country. In 2019, the annual WEI+ index was around 3%, and same 3% compared to the periodic average of water availability. The Long-term Annual Average Water Exploitation Index shows a slight decrease, but the trend is not statistically significant.

The quick rate of retreat of the Triglav Glacier, which began in the second half of the 20^thcentury, further accelerated till the beginning of the 21^st century. Due to increasing intensity of ice thinning, outcropping rocks began to emerge in the middle of the glacier, which disintegrated into two parts in 1992. In the last part of the first decade of the 21^st century, the glacier has been retreating at a slower rate. The last major recession of the glacier was registered after the above average hot summer of 2003.
