Age of vehicle fleet has impact on GHG emissions

Air pollutants

Are Slovenians considering buying an electric car?

Key message

SO₂and NMVOC emissions from energy sector in Slovenia decreased in period 1990-2012. Emissions of NO_x and NH₃ have not decreased as much as SO₂and NMVOC in the same time period. Emissions of PM₁₀ slightly increased between 1990 and 2012. This resulted in reduction of emissions of substances that cause acidification, ozone precursors and particulate matter. NO_x is the only substance with a significant proportion of emissions in transport and in production of electricity and heat.

In 2012, NO_x emissions exceed the target value, while emissions of SO₂, NMVOC and NH₃ were lower than the prescribed target value. To achieve the 2020 goals implementation of measures to reduce emissions of NO_x and PM_2.5will be needed.
