1.The Sin of the Hidden Tradeoff: The green version of the “glittering generality,” this sin involves presenting a product as green by highlighting a single environmental attribute (only focusing, for instance, on recycled content, or a manufacturer’s efforts to lower carbon emissions, without looking at the full range of environmental impact). 2. The Sin of No Proof: As the name suggests, this sin refers to making environmental claims that have no evidence to back them up.
