Green and Black's makes a business of ethical behaviour. Its products tick the right boxes: they are organic and they also guarantee - according to the company - a decent wage for their suppliers in the cocoa bean farms of Belize, Dominican Republic and Madagascar. But this is not pure altruism. Sales hit £23.4m ($41.4m) last year. This year, they are expected to rise by about 50 per cent to £34m.
