For an analysis of existing producer responsibility initiatives in the areas of packaging (of relevance to food), electronics and vehicles, see the Green Alliance report Return To Sender: Producer responsibility and product policy, Green Alliance, London, March 2005. The report concludes that 'if more is to be delivered through producer responsibility it is within the context of a much broader agenda that addresses products' impacts across their whole life-cycle. The ultimate aim is to transform the way we use resources to reduce impacts to within environmental limits.'
