In the period 2002-2021, the highest exposure to ozone concentrations were detected in the Primorska region in summer where air quality measuring stations in Koper and Nova Gorica detected highest ozone concentrations in ambient air. There are some differences from year to year in a level of ozone exposure due to meteorological conditions in the warm half of the year and other regional characteristics. 

Since 2017, as a result of the introduction of the fuel price supplement due to the mixing of biofuels, use of biofuels has increased. In 2020, 10.9% RES share in the transport sector has been achieved. Biofuels contributed 94 % to this share, with some biofuels multiplied by multiplier factors in the calculation of the RES share. Biofuels accounted for less than 6% in 2020 in transport energy use, with one sixth of advanced biofuels.

The phosphorus (P) budget in agriculture declined over the period 1992–2021 (for 104%). Reduction is the consequence of a decreased P intake with mineral and livestock fertilizers, as well as the consequence of increasing the P uptake by agricultural crops. The period up to 2003 was characterized by a surplus of 11 to 16 kg per hectare while after 2003 they were mostly less than 5 kg per hectare. In the period 2004–2015, the P surplus in Slovenia (+4.5 kg per hectare) was above the EU average (+2.2 kg per hectare).

Lyme borreliosis (LB) and tick-borne meningoencephalitis (TBE) are the most common vector-borne diseases transmitted by ticks. In Slovenia, from 3,000 to over 7,000 patients with LB were registered annually, and 133 TBE cases annually in the period from 2012 to 2021 (maximum in 2013 - 309 cases, the lowest number of cases was in 2015 and 2021 - 62 cases only). Living or working in the environments where there is a potential for infection is one of the most important factors for infection with LB and TBE.

One of the main reasons of mortality due to respiratory diseases is in Slovenia chronic pulmonary disease (COPD). The highest mortality rate due to respiratory diseases in Slovenia is in Savinjska and Zasavska region and the lowest in Central-Slovenian region (2017–2021). Mortality due to respiratory diseases is decreasing; in the period 2017 to 2021 it decreased from 62/100.000 inhabitants to 32/100.000 inhabitants. This can be attributed to the “harvesting effect” of COVID 19.
