The emission of off-road vehicles and their reduction options

Abstract The reduction of harmful emissions is a popular topic in both scientific and public circles. Contrary to popular belief, emissions from transport are only a small part of global emissions. As shown in the figure, the average of the EU 27 countries attributes only 15% of emissions from transport. From common perspective, vehicles with internal combustion, including diesel engines, will soon be replaced by alternative drivetrains. However at least at the commercial and off-road transportation, the diesel technology it is not so easy, and also the environmental reasons are questionable. Although the local emissions of electric vehicles are zero, their global emissions are, according to some research, more significant than their counterparts with internal combustion engines. The total electricity produced in the world in 2016 was about 25 PWh, two-thirds of which came from fossil energy carriers, which seriously damages the ecosystem, so it cannot be labelled as green energy.
