This study focused first on bringing together a group of recognized experts
in life cycle analysis of metals to identify the chief methodological
issues and difficulties in life cycle analysis of several metals (zinc,
lead, copper and nickel). Informed by that process, one or more life cycle
analysis/analyses of each of these metals was completed. The results were
evaluated in a final research workshop which was asked to develop recommendations. With the assistance of the International Copper Association, MMSD held a workshop on life cycle analysis (LCA) in New York on 9-10 August 2001. This involved 35 representatives of industry, government, NGOs and academia. One of the main purposes of the event was to discuss the draft report on a life cycle study of copper and by-product metals that was commissioned by MMSD and undertaken by Professor Robert Ayres and co-workers. This contains a global model of copper demand and supply. Following some debate concerning the size of remaining physical reserves of copper from a technical point of view, much of the discussion focused on how copper may be better managed as a global asset to society rather than as an expendable resource. The negative impacts of copper production - particularly in areas remote from the point of final use - were of concern to some participants. It was also clear from the meeting that there is an urgent need to assess the scope for increasing the recycling of this metal. Lack of data collection and availability on scrap flows in the major markets makes analysis of the potential for recycling difficult. MMSD hopes that the copper study will encourage parallel work for other metals. The meeting also involved discussion of the role of LCA in moving towards
more sustainable metal cycles. Contrasting perspectives of industry, government
and NGOs were presented. There was debate as to whether the conventional
environmental considerations of LCA can be extended to include the social
and economic implications of product manufacture and use that are relevant
to sustainable development. Many participants agreed that the quality
and transparency of data used in LCAs has to be improved if this tool
is to be applied more widely.
