There is evidence that car buyers in the UK are becoming increasingly environmentally aware.

According to a survey of 150 second hand car dealers by the car history checking service, HPI, reported in Fleet News, 72% have seen an increase in customer awareness of CO2 emissions.

54% of these cite taxation as the reason for the change, while 30% said it was due to a general awareness of the impact on the environment, and 28% attributed the change to an appreciation of the relationship between CO2 emissions and better operating economy.

Some dealers complained of a shortage of superminis at auctions.

49% of dealers saw Toyota as the leading brand for green vehicles, followed by Honda at 20% and Volkswagen at 5%.
