The high ratio of road transportation in
CO2 emission caused by humanity made the research
of relation between the road transportation and
climate change reasonable. There is a justifiable
demand by the society to moderate the environmental
impacts caused by road transportation. Our aim is in
this article to monetarise the impact caused by the
road transport sector in Hungary. First we analysed
the fuel consumption in Hungary then tried to
estimate the carbon dioxide emission from these time
series. According to the recent finalised EC founded
research projects we tried to monetarise the impact
of the transport sector on the climate. This is the
monetarised value which has been paid by the society
and not by the sector
