UK supermarkets should be forced to reveal how much packaging they produce, local councils say.
And why might that be, then?
"Supermarkets must be open with people about how much packaging they are producing," said Margaret Eaton, chairman of the Local Government Association, in a letter to Environment Secretary Hilary Benn.
"It is vital that consumers can make informed choices about where they shop and which products they buy."
Because there's no way that a consumer picking up a product can see how much packaging is on it, is there?
