One in every four fleet cars supplied by Alphabet now emits less than 120g/km of CO2.

Around 26% of the cars provided by the leasing firm in the first half of 2010 were rated at 119g/km of CO2 or less.

The number of sub-120g/km cars this year is 2900% higher than in the whole of 2006, when the company delivered 71 such cars. Eight percent of Alphabet orders this year were for cars rated below 110g/km and 1% were for cars under 100g/km.

Alphabet estimated that cutting CO2 emissions made cumulative cost savings for its customers of £2.9 million in fuel costs between 2007 and 2009. The drive to lower-CO2 cars reduced fuel consumption by 3.3 million litres and carbon emissions by 8750 tonnes.

The company said that the continuing shift to lower-carbon cars will save its customers a further £3 million at the fuel pumps over the next three years, despite projected rises in fuel prices.

Paul Hollick, general manager sales development at Alphabet, said: “The cars we supply today are 16% more efficient than those of five years ago. That means customers are spending less on fuel, in real terms, despite the huge increase in pump prices.

“We have been working with our customer base for some time, helping them set policy, review total cost of ownership and reduce cost. It is good to see the tangible outputs of these policies that were put in place in 2009.”

Alphabet expects its new-car carbon emissions to be below 140g/km by the end of 2010.
