Ecodesign in ongoing project is
based on LCA method, combined with Type III environmental declaration.
It calls for an integrated LCA modeling method
link to LCA database to provide background data
support,
facilitate transformation from product design to LCI /
LCIA and to indicators,
link to PCRs for directions of improvement.
