There continues to be increasing public and private company interest in reducing the carbon footprint of their fleet vehicles.There are a number of promising technologies becoming available including hybridization, full electric power, bio-fuels, and natural gas fuel.Each technology offers different levels of CO2 reduction and incurs different costs to implement.Currently some of these options are prohibitively expensive.However, for certain vehicle applications the technologies can make economic sense today and a broader deployment of technologies could be affordable in the future.The presentation will describe different fleet vehicles and their usage profiles.For key vehicle vocations, the technology and cost reduction roadmaps will be presented.Affordability of the different technologies will be analyzed based on total cost of ownership of the vehicles.The potential for well to wheels CO2 reduction will also be presented.The synergies between the different technologies will be discussed along with the roadblocks to implementing these pathways will be reviewed.Affordable pathways will be suggested to achieve goals such as 1990 CO2 levels by 2020 and 80% of 1990 levels by 2050.
