Air pollution is the most important environmental risk factor for human health, affecting an average of 400,000 premature deaths in the EU and costing Europeans an average of more than € 166 billion a year. In the case of the cities of Ljubljana and Maribor, external costs amount to almost EUR 271 million annually. Estimation of external costs of air pollution from transport is slightly decreasing.

In Slovenia, the market prices follow the trends at the key agricultural markets, globally or regionally important. Market prices of grain are following the trend and the level of EU average, prices of beef are below EU average while the market prices of eggs and pig meat are above the EU average. Slovenia stands out with its market prices of milk, which are among the lowest in the EU.

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.

Greenhouse gas emissions from agriculture, mainly methane and nitrous oxide, decreased by 11.0% from 1986 to 2019. The largest declines occurred in pig and cattle production and in fertilizer application to agricultural crops. The rapid decline in emissions was typical of the early years of this period. After that, the decline slowed down. In 2019, Slovenia achieved the target (0.3% increase of greenhouse gas emissions compared to 2005) set by Operational programme for limiting greenhouse gas emissions until 2020 (increase by a maximum of 5% compared to 2005).
