The squeeze on car advertising might not stop there.
British Lib-Dem MEP Chris Davies is among the leading supporters of even more stringent controls. He believes the current directive does not help provide consumers with sufficient information to make informed choices, and is backing plans for 20% of the surface of adverts to be given over to economy and emissions figures.
TV, radio and internet ads, currently outside the directive, could also be sucked in.
'My main focus is on reducing CO2 emissions from cars, but I will be supporting the labelling directive,' Davies said. 'Until the recent hike in fuel prices, consumers rated economy and emissions as low priorities. It is better to have measures which force them to pressure manufacturers into providing that information.'
