Air pollutant emissions have decreased in the period 2005−2020 to the levels that enable Slovenia achievement of its 2020 targets. But to reach 2030 targets additional decrease is needed. Reduction of emissions contributed to lower impact on ecosystems and human health, as emissions of pollutants that contribute to acidification, ozone precursors and particles, decreased by half compared to 2005.
