Barclays is reviewing its fleet policy to help reduce the carbon footprint of its 8,400 company car and cash allowance drivers.

It is considering changing the types of vehicles available for drivers to choose from and educating staff on the benefits of selecting greener vehicles. The review will also provide an opportunity for the bank to set a target average level of grams per kilometre of carbon output for the entire fleet.

Caroline Sandall, fleet manager at Barclays, said: "We are in the middle of a project to examine the sort of changes that we can make to the fleet policy to help on the green side of things.

"It is early stages, but we are looking at [company] car drivers and people who take the cash [allowance] for cars too."

The bank would like its fleet drivers to be able to make informed decisions on the car they drive, and ensure employees realise that prestigious manufacturers produce low-carbon vehicles.

"We need to make our drivers aware that those who want a BMW or an Audi can buy low CO2 cars from these manufacturers as well," said Sandall.

Barclays expects to develop its new policy by the end of the first quarter of 2008.
