Comprehensive life cycle assessment by transferring of preventative costs in the supply chain of products. A first draft of the Oiconomy system

The price factor represents the marginal preventative costs for the relative impact category of sustainability issues. For initial determination of the price factor this article extends the EcoCost/Value ratio system, developed by Vogtländer et al., to social issues, discusses implications of the system, its principles, advantages, research challenges and limitations and proposes system boundaries for application of the system and future research contributions to the project.
