[A new report by World Vision Australia] recommends that the chocolate industry adopt a ‘sustainability levy’ on cocoa that will amount to about 0.2 percent of global chocolate sales...Evidence listed in the report shows that child labour and, more disturbingly, the worst forms of child and trafficked labour are still rife in cocoa production in West Africa...World Vision recognises that some of the big chocolate companies have committed to phasing in the use of ethically certified cocoa, with Cadbury offering one Fairtrade Certified Easter egg for the first time this year..."Our report shows only 1-3 percent of global cocoa supply is ethically certified today," [World Vision CEO] Costello said. "In addition to ethically certifying their cocoa, big chocolate companies need to pay a fair price to farmers for their cocoa and invest in farmer training and monitoring programs."
