Figure 9 depict scenarios for the future development of vkm driven for above describedscenario up to 2030. It can be seen that due to the standards vkm driven are higher thanin BAU-Scenario. As shown with the increasing fuel tax, travel activity could besignificantly reduced. However, the lower increase in vkm driven could be reached, asshown in Policy Scenario.The future development of energy consumption in four scenarios described above withand without rebound up to 2030 is shown in Figure 10.Due to the efficiency improvements increases in energy consumption are not as steep asfor service, see Figure 10. The pure Standard-Scenario shows lower energy consumptionthan BAU-Scenario (on contrary to the effect in Figure 9) and the Policy Scenario leadsto lowest energy consumption.70006000Energy consumption (PJ)50004000300020001000E-HIST E_BAU E_TAX E_STAND.

6 ConclusionsThe major conclusions of this analysis are:The intended introduction of standards as announced by EU (130 gCO 2 /km in the period2012-2015, and 95 gCO 2 /km by 2020, see Section 2) will not lead to the expected ordesired overall energy savings and CO 2 -reduction. The major reason is that the reboundeffect due to more km driven and larger cars will eat up most of the theoreticallycalculated savings. Yet, a simultaneously introduced tax in the magnitude of 30% up to2020 will compensate this rebound even without hurting car drivers due to service kmdriven remaining at same service price, see Figure 12. So finally a combined taxstandardpolicy will lead to a win-win situation from which the environment benefits andcar drivers are not hurt.PsPs 0η 0Taxη 1E 0EFigure 12.
