Follow up question on LCA team conclusions 0 C. Stahl Thanks to the LCA/sustainability writing team #3 for their contribution to the initial discussion about whether LCA takes care of addressing sustainability.  A followup question for those (either on team #3 or anyone else) interested is a statement made in the meeting notes that says that "LCA is necessary but not sufficient to address sustainability."  So, turning this question on its head, Do you think that it's possible to address sustainability without engaging in LCA?  If so, why and how?  If not, why not?  Please post your thoughts to this Forum.  Remember, we're just discussing and you can change your mind later -- even several times, if you like!  So, be bold in your replies!

Subgroup on LCA/LCSA Output 0 B. Vigon The subteam to respond to the statement  'LCA/LCSA takes care of addressing sustainability' has completed it's work. Attached is the summary document - generated in our meeting on April 5 as well as articles referenced in that document.  We were very fortunate to have team members that created these publications - that made our life a lot easier! As expected we did raise additional questions that we feel might be good ground for discussion within the leadership team of the Sustainability AG and likely will lead to new projects.

ideas on content for topical paper 2 B. Vigon Another relevant idea comes from the literature on Jevons Paradox.  There is the abbreviated reference on the AGS site under References/Reading materials.  But there is also "The Myth of Resource Efficiency:  The Jevons Paradox" by Polimeni, J.M. et al.  2008, Earthscan.  If you have this reference or get it, go to page 21-22 under a section titled "what is output?"  There is a discussion of utility and externalities that seem relevant to LCA.  There are other (obviously) relevant ideas throughout this reference but it seems that the concept of who decides (and how you decide) what goes in the numerator is an important idea.  In Jevons original work (1800s), he states that utility is not an inherent value -- meaning that the utility of something changes depending on how much you currently have of it as well as context (e.g., how useful it is now compared to some other time).  In this context, it would be interesting to discuss whether and how LCA might change over time -- should it or shouldn't it?  Are the elements that go into LCA fixed (like a standard set of indicators or criteria)?  If not, when do they change?  Who decides? If so, why and who decides?  Just some ideas to ponder.  Thanks for your efforts!
