Corporate decision makers sometimes call on FCA/TCA measures to decide whether to initiate recalls, practice voluntary product stewardship (a form of recall at the end of a product's useful life). This can be motivated as a hedge against future liabilities arising from those who are negatively affected by the waste a product becomes. Advanced theories of FCA, such as Natural Step, focus firmly on these. According to Ray Anderson, who instituted a form of FCA/TCA at Interface Carpet, used it to rule out decisions that increase Ecological Footprint and focus the company more clearly on a sustainable marketing strategy.
