Establishing In-Use Vehicle Stock and Vehicle milages

Approaches for Establishing In-Use Vehicle Stock and Vehicle Mileages Background Paper

Reliable data on the number of vehicles in use by vehicle type and on vehicle mileage form an essential input for a bottom-up emissions inventory for transport (Figure 1). This background paper covers approaches which serve to establish vehicle mileage. In addition, the paper presents methods applied in Germany, USA and France to obtain an up-todate vehicle register. Hence, the paper deals with the first two of the three main components for establishing a bottom-up emissions inventory. The focus of the methods discussed in this paper is the passenger car. Special attention is given to the applicability of the presented approaches to two-wheelers. The objective of this paper is to discuss the methods, their strengths and weaknesses as well as the context of the different approaches. This will help identifying approaches which are suitable for application in different contexts, for example in Vietnam.

The paper begins with an overview over the institutions involved in establishing vehicle mileages in Germany. Thereafter, we will present the approaches used in Germany, France and USA to maintain the vehicle register and continue to show the different approaches to assess VKT1 . Finally, this paper presents options to establish vehicle stock VKT statistics in Vietnam as discussed in the workshop in Serena Resort on July 12 and 13.
