LCA and the ability to track sources

With my work at Walmart this summer I've gotten to understand the practice of LCA (Life Cycle Analysis).  Basically, it's a tool that helps identify environmental (and perhaps very soon social) "hotspots" within a supply chain. 

Usually intuition is correct but sometimes the findings can be very surprising.  For instance, 97%ish of the impact in the manufacture of a lightbulb (CFL or incan) is from the consumer use phase.  All the mining, manufacture, transport, storage, etc makes a fraction of the carbon impact of what happens when the lightbulb is screwed in.  This analysis can also make for interesting environmental dilemmas like the Local British lamb having a higher carbon footprint than New Zealand lamb even when eaten in London! 

You can see an interesting take on LCA with the Open Input Output project, created by the Sustainability Consortium here:

While LCA has a long way to go to achieve total supply chain transparency when I saw this photo below I was wondering how long it will be before we (consumers, suppliers, large energy users) know how much of this specific coal from this former mountaintop in WV is going to burn our lightbulb.  Would that make your house more energy efficient?  Maybe OPOWER should send this picture with their energy consumption data once they are armed with the data of where this coal is going?
