Abstract

This paper spatially extended the vehicle life-cycle analysis of a single country and developed a new method for vehicle life-cycle analysis by combining a 15-country automotive stock-flow model based on the 15-country automotive lifetime distribution with global multi-regional input-output analysis. From the results, considering that ten of the 15 countries had vehicle lifetimes shorter than the average of 15.8 years: Austria, Canada, Germany, France, the U.K., Ireland, Italy, Japan, South Korea, and the Netherlands, we found that by increasing the average vehicle lifetimes of these 10 countries to the global average of 15.8 years, a reduction of 17 Mt-CO2-eq. from the carbon footprint of the 10 countries could be achieved. In addition, we also revealed that roles of changes in vehicle lifetime and fuel efficiency on global CO2 emissions are vastly different between countries where vehicle lifetimes are longer and those where lifetimes are shorter.
