Britain's most popular chocolate bar, Dairy Milk, is to become Fairtrade certified in Britain and Ireland in a move that will double the amount of cocoa bought from smallholders in the developing world under the sustainable farming scheme.
The decision - the highlight of Fairtrade Fortnight - will transform Fairtrade chocolate from a niche preference to a mainstream ethical benchmark, bearing the sustainability kitemark on 15% of chocolate sold in Britain. Cadbury's chief executive, Todd Stitzer, said he plans to convert the group's other chocolate brands to Fairtrade "as soon as we can do it". Dairy Milk is the first mainstream chocolate bar to be sold with a commitment to pay cocoa suppliers the "Fairtrade premium" of $150 (£105) a tonne above market prices. When the bars go on sale this summer the value of Fairtrade chocolate sales in Britain will leap from £45m to £225m. Cadbury's pledge to buy 10,000 tonnes of cocoa under Fairtrade terms will triple certified sales from Ghana.
