Conclusion and perspectives
LCA = essential tool in an Eco-Design view
Details the environmental impact potential improvements
Avoids impact transfers from one category to another or between life cycle steps
Accurate environmental performance measures internal and external communication
ReCiPe : several impacts categories
Study other eco-Design strategy (other indicators, other ways, etc.)
