To oversee the study a core group of IZA members and staff were assembled to direct, review and coordinate activities associated with methodology, data collection, modeling, as well as the appropriate presentation and dissemination of the LCI results. The seven core group members and their affiliations at the time of the project were:
• Bill Adams [Rio Tinto]
• Anne Dekker [Nyrstar]
• Christian Canoo [IZA]
• Andrew Green [IZA]
• Walter Kuit/Mark Edwards [TeckCominco]
• Robert Prairie [Xstrata Zinc]
2. Allocation of burden to co-products has been already addressed within the model for this dataset. The results include credits to the zinc production system equivalent to the environmental burdens associated with the production of sulphuric acid from nonferrous sources as well for other co-products like lead, copper, silver and gold. Allocation to co-products within the precursor chains is documented within the GaBi database documentation.
