In the transport sector, it is assumed under the Energy [R]evolution Scenario that energy demand will almost double to 5,300 PJ/a by 2050, still saving 46% compared to the Reference Scenario. This reduction can be achieved by the introduction of highly efficient vehicles, by shifting the transport of goods from road to rail and by changes in mobility-related behaviour. The African car fleet is projected to grow by a factor of 6 to roughly 100 million vehicles. Development of fuel efficiency is delayed by 20 years compared to other world regions for economic reasons. By 2050, Africa will still have the lowest average fuel consumption.
