Yes, which is why the companies promote passing the buck on to consumers rather than backing effective regulation. I'm reminded of cafe chains that give you 5p off a coffee if you use a reusable cup because they just love the environment so much but then lobby against imposing the same 5p charge via taxation. This is why the emphasis has shifted. Consumers already have to consider when buying a product without investigating its entire supply chain.
