The Department for Transport (DfT) has launched an advertising campaign aimed at reducing CO2 emissions from car use.

The TV advert highlights that by driving five miles less a week any driver can help make a difference.

Car travel is the single biggest source of household and individual CO2 emissions in the UK, according to the DfT.

If all UK drivers reduced their driving by five miles a week it says savings of 2.7 million tonnes of CO2 per year could be made.
