A survey of 150 used car dealers in Britain says that seventy-two percent of buyers are more aware of the cars' CO2 emissions of the cars. There are a number of different reasons for this with fifty-four percent citing taxes as the reason. This would particularly make sense for drivers who go into London where cars with CO2 emissions of less than 120 g/km are exempt from the congestion charge. Another thirty percent cited general environmental awareness while twenty-eight percent have realized that CO2 emissions are directly related to fuel consumption.
