The vehicle funding and fleet management provider has seen CO2 emissions drop to 116g/km per vehicle for all new cars ordered in the first quarter of 2015 as corporate customers increasingly specify green models.

For the year to the end of March, some 28% of all new cars ordered across the 18,000-strong Fleet Alliance vehicle fleet have been sub-100g/km of CO2, with 81% of them less than 129g/km, as the green message hits home.

In a league table of the cleanest cars, the top 10 models on the company fleet now all have carbon emissions of 95g/km or less.

The greenest car on the fleet with emissions of just 44g/km is the Mitsubishi Outlander PHEV followed by the Lexus CT Hybrid, with carbon emissions of just 82g/km, which the company now includes on its own company car policy to encourage employees to consider greener alternatives.

In third place in the green stakes is Skoda’s Octavia estate GreenLine III Business TDI, which has carbon emissions of 85g/km. Ford’s Fiesta ECOnetic comes next also with carbon emissions of just 85g/km for the 1.6 TDCi-engined model.

Skoda stablemate Volkswagen claims fifth spot with the Golf BlueMotion 1.6 TDI estate at 87g/km, followed by the Volvo V40 hatchback D2 ES hatchback with carbon emissions of 88g/km and the Ford Focus ECOnetic 1.6 TDCi also with emissions of 88g/km.

Also sub-90g/km on the Fleet Alliance fleet is the Citroen C4 Cactus 1.6 BlueHDI crossover, which has carbon emissions of 89g/km.

Speaking on the trend for the decline in its customers’ carbon emisisons, Fleet Alliance managing director Martin Brown commented: “This will continue to fall as clients increasingly follow our advice and switch to greener cars. This has the effect of not only cutting their carbon footprints but reducing their tax and fuel bills too.

“At the same time, vehicle manufacturers are playing their part by introducing new models with ever-lower carbon emissions across all popular model ranges.

“And the fact that the cleanest two models on our fleet are now both hybrids shows they have a real role to play as a key part of the fleet mix. Electric vehicles are for the future but hybrids are definitely for the here and now,” he said.
