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.

In 2018, the ecological footprint of Slovenia was 5,37 gha per capita while biocapacity was 2.2 gha. For such a lifestyle 3.39 Earths would be required for the world's population to live within planetary regenerative capacity. This places Slovenia above the average of the EU countries (4.6 gha per capita). The carbon footprint usually accounts for around 60% of the total ecological footprint and therefore needs to receive comparatively more attention. According to consumption categories, housing and personal transportation contribute the most to the ecological footprint in Slovenia.

Energy use contributes 79% to total greenhouse gas emissions in Slovenia. The biggest sources of emissions are electricity and heat production and transport. With the introduction of the EU Greenhouse Gas Emissions Trading Scheme (EU-ETS) Member States targets for GHG's covered only emissions from nonETS sources. Transport is by far the largest source of on nonETS emissions in Slovenia with 47%, while  emissions from energy use contribute 73%. The 2020 target has been achieved. Target for the following years are significantly more ambitious.

The export of waste from Slovenia decreased in 2020, for the first time after ten years of growth. We exported around 340 thousand tonnes of waste, mainly to Austria and Hungary. The import of waste also declined for the first time in 2020, we imported around 61 thousand tonnes of waste.

The results of the Slovenian Energy Efficiency Survey (REUS) 2019 show that over three quarters of all households decrease their greenhouse gas emissions by walking short distances, about half of them travel by bike, 1 in 7 uses public transport and 1 in 8  uses car sharing. Seven out of ten households were willing to combine their personal vehicle with other forms of transportation in their daily travel.
