Householders are saving £296 million a year by reducing food waste, since the Love Food Hate Waste campaign launched in 2007.
According to figures from campaign organisers, the Waste & Resources Action Programme, more than 1.8 million more households have cut back the amount of food they throw away. This means waste food has been reduced by 137,000 tonnes, preventing 600,000 tonnes of greenhouse gas emissions.
The campaigns impact so far was measured using data from WRAP's Love Food Hate Waste tracker from the past 12 months. Research from The Food We Waste report was also used.
WRAP chief executive Liz Goodwin said: "At a time when every penny counts, saving nearly £300 million is a great achievement for hard pressed consumers. Food which ends up in landfill produces damaging greenhouse gases and is a terrible waste of resources. We're delighted that the Love Food Hate Waste campaign is helping individual households enjoy more of their food, help the environment and save money.
"We recognise that although the results of the first year are encouraging, there is much more to do, and we're confident we can continue to support the growing number of households cutting back this waste."
