Globally, the number of motorized vehicles is estimated to reach between 2 and 3 billion vehicles by 2050 with a significant number located in developing countries like Zimbabwe. Zimbabwe's motor vehicle fleet has been growing at a fast rate especially after the year 1990. The Zimbabwe Climate Change Response Strategy further identified that the nation's transport sector consumes over 1 billion liters of diesel and over 730 million liters of petrol annually.
