A historic exercise book

August 20, 2019 by Bo Weidema

References to my ‘ancient’ 1994 exercise book come up from time to time. Therefore we have today decided to share a simple scan of this book, to make it available for discussion within the LCA community. Someone might take inspiration for an updated version with modern LCA techniques?

The book contains two fictional LCA reports on baby diapers, which make use of the same data, interpreting these differently. This causes diverging results. The book was intended to allow students to discover by themselves the implications of certain methodological choices or assumptions.

The book is very outdated in many respects (eg. the impact assessment methodologies and the state of data gathering and interpretation). But the overall teaching methodology seems to be still valid. Nothing like ‘walking the talk’ to improve learning. This is even to this day our concept at International Life Cycle Academy.
