Management of metadata applied to life cycle inventory (LCI) and life cycle assessment (LCA) data is provided. Life cycle inventory data may be provided through a secure framework to a data hub where it may be validated and audited and where the received life cycle inventory data may ultimately be used to generate a life cycle assessment score for a given product. Life cycle inventory data may be provided via a structured data template provided by a supplier or obtained by a supplier via a requested unit business process model. Metadata may be applied to each LCI data item to allow the data items to be stored, sorted, search, retrieved and used for validating and auditing the data and for comparing the data to other data items of similar data types for eventual use in the generation of the aforementioned life cycle assessment score for a given product.
