Contribution of Passenger Cars and Trucks to CO2, CH4, N2O, CFC and HFC Emissions 2001-01-3758

Global and regional greenhouse gas emissions of natural and anthropogenic origin are estimated. Biogenic CO2 emissions are globally 770 billion t/year and anthropo-genic CO2 emissions in 2000 are 28 billion t/year. Assuming that biogenic emissions are in a equilibrium only manmade CO2 emissions for comparisons are used. Regarding only the anthropogenic CO2 emission road transport contributes globally about 10 % and regionally in Europe about 20%. The contribution of road transport on the total CH4 emission is globally less than 0.2%, regionally about 1% regarding only the anthropogenic CH4-emission road transport contribute globally less than 0.5% and regionally in Europe about 2%.
The contribution of road transport on the total N2O emission is globally less than 0.3%, regionally less than 2%, regarding only the anthropogenic N2O emission road transport contribute globally less than 1% and regionally in Europe about 10 %.
The contribution of road transport on the total CFC-emission is globally less than 0.1%, regionally about 0.2%. All CFC emissions are anthropogenic.
