This study is a follow-up to an earlier TNO Institute of Spatial Organization's (INRO-TNO) study (See IRRD 853141). The follow-up study describes both the methodology and results of a literature study into purchasing patterns amongst new car buyers, and the influence of fuel consumption and emission output upon purchasing behaviour. No important new research was found to supplement the earlier INRO-TNO study with regard to fuel consumption. It may be concluded that there are sufficient technical possibilities for improving fuel consumption. The introduction of the relevant technologies to production vehicles requires either strict policies or a change in consumer attitudes. As regards emission reduction, a number of studies have been made which shed light on the cost of emission reducing measures. However, only one study carried out in the United States examines the consideration given to emissions by consumers: Kitamura places a value on the new car purchaser's 'willingness to pay' for emission reducing technology. It already appeared that this technology can be effective, when introducing the catalytic converter. The amount which Dutch consumers are willing to pay should be ascertained, before tax incentives are introduced to encourage either fuel efficiency or emission reduction.
