The Government will today launch an ambitious scheme to turn 'white van man' green.
Transport Secretary Alistair Darling will travel to Nuneaton to launch the £1.3 million Safe and Efficient Drivers initiative, offering advanced driving courses to encourage cleaner, cheaper van fleets.
A pilot project has shown better driving techniques can potentially save up to £500 per vehicle per year, at current fuel prices, as well as significantly reducing carbon emissions.
The Department for Transport believes ten per cent better fuel consumption can be achieved through techniques such as better use of gears, avoiding "dabbing" brakes by keeping correct distances, and better general road awareness.
The DfT said the pilot saw gear changes cut by half but still showed no noticeable effect on delivery times.
A DfT spokesman said: "Just as a doctor or teacher constantly works at their skills, we want to give wider opportunity for van drivers to do the same. Advanced driving schemes such as we are announcing today, can save them money and save on carbon emissions."
Other potential benefits from the scheme are fewer accidents, lower insurance premiums, lower running costs and higher resale value.
Mr Darling will announce the SaFED scheme to train 200 instructors to offer training to 3,500 drivers for free.
The scheme will start with drivers from the Royal Mail and Sainsbury's but the instructors will then market themselves to companies across the country to change habits among Britain's 195,000-strong white van drivers.
