Sainsbury's was embroiled in an embarrassing row yesterday after claims that its "green" shopping bag was anything but ethical...But yesterday it emerged that the bag was made in China, a country known for appalling labour conditions. And environmentalists described as hypocritical the use of conventional, rather than Fairtrade, cotton...The supermarket said the carrier was made in a factory that pays double the minimum wage for that province and complies with all aspects of Chinese labour law, as well as having operations reviewed by a human rights consultant.
