Take a look

Alternative drives are dominated by electric vehicles and hybrids

Fossil fuels private cars are dominant mode of transport in Slovenia

Age of vehicle fleet has impact on GHG emissions

Key message

Emissions of greenhouse gases, methane and nitrous oxide, in agriculture were reduced by 11.5% from 1986 until 2010. The reduction is mostly the result of decreased cattle, pigs and poultry population, as well as improved livestock manure management.
