## Context

MOTION is a research project for ecodesign of glass making stainless steel tools.

Life Cycle Assessment (LCA) methodology is applied for evaluating environmental impacts. It is a leading methodology, but is criticised for being time-consuming and inconsistent due to numerous "modeling choices".

This study lies in field of ecodesign and has pre-existent framework, tools and sectorial rules. However, ADEME's requested to handle social, economical and environmental attributs combined to ILCD compliance. They put us in a position that we could not miss the present results.

## Goals: & Method:
* Understand the causes of current LCA faillure and identify solutions to overtake them.
* Analysis of LCA's function, reviewing current LCA methodology and criticisms.

## Acknowledgement

I thank my director and supervisors for their trust as I evolved farther away from their fields. I thank the funders and partners of the project. I thank my colleagues, more particularly Dr. Hadrien ROUCHETTE, for the discussions and debate they took part in and that probably put me in the environment enabling my reflexions and results. I thank Coen VAN DER GIESEN MSc from CML for sending me DAVIS's work. I thank my sister Guisela PATARD, PhD researcher in PSITEC Lille 3 for her help and guidance in psychology fields. Finally I thank all the researchers for their work and the act of making it available as LCA, as collaborative discipline, would be nothing without them sharing.
