Car clubs are clearly an area where further investment (TfL is providing
d1 million in support) could yield significant and quick savings. In 2008
there were 34.7 million driving licence holders and 27 million private cars
(DfT, 2010a) with the average vehicle covering 9,241 miles. Assuming a
change from an average vehicle, halving emissions would save around 0.8
tonnes CO
per vehicle.
