Environment preservation is an important issue for this century and Life Cycle Assessment (LCA) is a relevant methodology to tend towards cleaner production and sustainable development. The LCA training of the new generation of engineers is imperative. But teaching LCA is a hard task principally because of the lack of time to go into LCA methodological key points in depth and to carry out a sufficiently complex LCA case study to apprehend interest and limits of the use of this methodology. In AgorAcv network (network of scientists and consultants in LCA at Western France) a working group of six teachers shares educational approaches and tools to teach LCA. We analyse the different ways of teaching LCA in AgorAcv network. This analysis of the nineteen courses of these six teachers shows some similarities and some discrepancies as original ideas to teach LCA.
