The purpose of the contest is to drive the economical, fuel-efficient Volvo C30 DRIVe round the world, using a network of contacts. The Volvo C30 DRIVe has a fuel consumption of 74.3 mpg, enabling it to cover 825 miles on a tank of fuel. This means that each participant drives the car for 825 virtual miles before passing it on to a Facebook friend, who in turn does likewise. The circle is completed when the car returns to its original starting point. The various teams' routes round the world can be followed on Volvo's Facebook page.

The winning team's reward will be a donation of 15,000 Euros to a carbon offset project through the organisation myclimate to help reduce global warming. Myclimate works according to the Gold Standard, which is certified by the U.N. and has been formulated by, among others, WWF International and Greenpeace International. The donation is enough to neutralise the amount of carbon dioxide generated by the average person during a lifetime.

For each additional driver, Volvo Cars will contribute funds that are the equivalent of 99 grams of carbon dioxide, which is the level of a Volvo C30 DRIVe's emissions per kilometre.
