The awards recognise organisations that show their commitment to minimising their impact on the environment by cutting carbon emissions from business travel.

At the third annual awards held at Covent Garden's London Transport Museum, the Agency was rewarded by the Fleet Heroes judges for its innovative driver training policy, which focuses on both road safety and environmental responsibility, and which has dramatically cut the Agency's fuel consumption.

The Agency was also runner-up in the Fleet Heroes 2008 Leadership Award in recognition not only of its bold approach to cutting its own carbon emissions, but also for leading the business transport industry by example and being in the vanguard of the sector's efforts to make their services sustainable.

Green Cars, GCDA's taxi service for government and public sector clients, uses hybrid fuel cars and produces half the carbon emissions of traditional black cabs, and now runs the biggest low-carbon taxi fleet in London.

Where contractors provide the same service for the public sector on GCDA's behalf in the regions, they are being strongly encouraged to switch to greener, low-carbon vehicles. Finally, where carbon emissions are unavoidable, GCDA offsets them through the government's Carbon Offsetting Fund.
