1. January 21, 2004 slide 1 Auto Sector LCM Methodology: Ideas Lise Laurin Sylvatica Suppliers Partnership for the Environment (SP) Design for the Environment (DfE) Work Group January 21, 2004

2. January 21, 2004 slide 2 Needs for Auto Sector LCM Methodology Common Basis –Recognized process for suppliers, OEMs –Consistent data, starting assumptions Design flexibility –Countless creative and unforeseen design ideas –New regulations, new environmental emphases, issues –Throughout supply chain Rapid and efficient results –DAYS not weeks or months –Support Strategic Decision making –Use by variety of experts in things other than LCA Screening, not full-blown LCA

3. January 21, 2004 slide 3 Flipping the natural tendency around Natural tendency –Streamline (leave out LC stages, environmental issues) –Condense (black box “indicators”) –“Quick” “Back-of-the-envelope” –“Screening may lead… –Do a real LCA “later” Flip: Max Use/Power from Existing Data Capital –Put existing LCA results into what-if-able, easy-to-use scenario evaluator –Data, details, common assumptions in background –User ideas, creativity, questions in foreground

4. January 21, 2004 slide 4 Key: Smart Use of Existing Models/Data Given LCA model of a representative car: –Supply chain processes in a linked model –Material choices and amounts –Influence on performance characteristics –Use phase model –End-of-life fate option models Need: –Rapid, non-LCA-expert WHAT-IF analysis –New ideas, altering one or more aspects of baseline –Draw on full richness of model, in SECONDS

5. January 21, 2004 slide 5 A Proven Approach Build an easy to use user interface on top of existing software. Make this interface adaptable to the kind of problems that are to be analysed. Develop the interface in such a way the user is not confronted with methodological issues Supply a relevant data set

6. January 21, 2004 slide 6 Split the functional unit from the LCA expert part The User can define the functional unit The LCA expert defines the Script interface Description of the product and the life cycle Script interface Advanced LCA software and data Non expert userLCA expert

7. January 21, 2004 slide 7 Transparency for experts-in-other-things Comprehensiveness is THE value-added by LCA Full LCA software and models contain detail not relevant nor accessible to experts in other things “Have cake and eat it” Our solution: LCA SCRIPTS. Works with predefined LC structure and rich LCA databases, models Easy to use, yet fully transparent

9. January 21, 2004 slide 9 Proven Packaging sector, supply chain, and users Cement sector, supply chain, users Tire manufacturer Others…

10. January 21, 2004 slide 10 Conclusion: Full power and transparency Provides Full Access: –Full LCA model scope: all life cycle stages –Full detail in processes: ability to change 1 number, alter whole LC –All flows: relevant as environmental issues, LCIA methods change –Flexible ability to analyse and understand the results Find hot-spots Find tipping points Results in minutes; users change/input only the relevant Scripts can be programmed by experts, to facilitate the application of the data by non experts. Maximum use of existing data capital: TRUE life cycle
