After my earlier post about elephants and fuel efficiency, I came across this, coolfleets, put together by the Sierra Club and Donlen Corporation, It lets you compare the price of running a number of different types of car fleet. The intro says:
coolfleets.com was developed to assist commercial, government and municipal fleets in modelling vehicle alternatives to gain a better understanding of both their carbon output and life cycle costs. Car and truck fleets are significant contributors to greenhouse gases and the selection of vehicles that are more fuel efficient can not only reduce CO2 but can also result in lowering the total costs of fleet operations.
Worth looking at. |Hat tip to Sustainablog
