In the UK, there was something in the news this last week about mainstream chocolate (e.g., kit kats and the like rather than 'posh' chocolates) with fairtrade labels plastered all over them. They're designed for people to think the chocolate is fairtrade, but are using something called the mass balance system, which means if a large company buys 90% normal cocoa beans, and 10% fairtrade, mix them all together, they can label 10% of their products as fairtrade even though the particular product they label as fairtrade will have hardly any fairtrade chocolate in it and indeed no more than the other 90% of the products they cannot label fairtrade. That makes it pretty hard for people to make an informed decision so I'd guess that is an example of UK greenwashing.
