putting the responsibility solely on the brand owners, retailers and consumers.
To my mind, the manufacturers are not "simply" compliant suppliers to the brand owners. The idea that container (or any other) companies just deliver "what the consumer wants" ignores the influence of aggressive advertising and marketing, and you can be sure that in this competitive industry, marketing is at a fever pitch. Consumer demand--whether at the retail or wholesale level, does not merely "exist;" it is continuously created and manipulated.
In theory, the most effective bills would target all the parties along the supply chain.
