ECO EFFICIENCY INDEX
Objective comparison of solutions have to be made on
the basis of the life cycle assessments (LCA)
Satisfaction of users’ and customers’ needs must also
be taken into account!
Development of an ECO EFFICIENCY INDEX =
Satisfaction of needs
Eco score
New methodology to assess the satisfaction criteria
Results are sometimes surprising and against wellestablished
ideas!
