Abstract
This paper shows the importance of including regionspecific circumstances in longterm climate change mitigation strategies by example of a modeling exercise of the transport sector Important emission reduction options in the transport sector include biofuels electric vehicles and efficiency standards The most effective combination of these options depends among others on the availability of biofuels the effectiveness of efficiency standards and the expected emission intensity of the power sector—all of which differ between regions Differences in climate policies between regions influence these factors For instance fuel efficiency standards slowdown the longterm transition in regions where plugin hybrid electric cars compete with gasoline cars such as the USA or Europe by decreasing the costs for driving gasoline costs and therefore in fact increase longterm emissions Another example is that promoting electric vehicles is less effective in regions which are expected to rely heavily on fossil fuels for power generation such as South Africa China and India Based on these findings from the TIMER energy model we introduce an indicative regionspecific framework for assessing mitigation strategies for the transport sector up to 2050 for different ambition levels of climate policy
