The fast food chain aims to switch all its 155 vehicles to run on biodiesel in the next 12 months, it told Reuters.
The process will start on Monday with half its 45-strong fleet based in Basingstoke, in southern England.
The biodiesel will be made up of 85 percent used cooking oil collected from around 900 McDonald's restaurants and 15 percent from pure rapeseed oil.
By using the fuel, McDonald's will save 1,675 tonnes of carbon per year, the statement said.
