CO2 discharge reduction during atotal life cycle
Quantity of CO2 discharge
Don’t forget to evaluate burden to environment of CO2 discharge during the total life cycle of machinery
Even if CO2 discharge during manufacturing/molding stages of a innovative material exceeds that of
the conventional material, LCA of an innovative material possibly has big advantage in terms of the overall
CO2 discharge burden to environment.
JCMA ProprietaryIllustration of quantitative LCA ofcontribution of carbon fiber for CO2 discharge reduction“Made in accordance with JCMA assessment model”<Adopted assumptions>・Domestic-flight type medium-sized passenger aircraft (Boing 767)
・Domestic flight between Tokyo-Haneda airport ⇔ Sapporo-Chitose
Airport (both ways 5,000 miles)
