Citroen is to offer a further six cars emitting under 120g/km CO2 by the end of the year.
Fleet boss Ian Hughes confirmed the brand would be expanding its range of sub-120g/km vehicles to 30 in the next few months.
Citroen was unwilling to reveal which cars would be joining the range. The 24 currently available include models from the C1, C2, C3 and C4 ranges.
All Citroen vehicles emitting sub-120g/km CO2 fit the criteria for the company’s green iniative labelled Airdream.
