G-02 Classifying the decision context as situation A, B, and C for building and product LCA
Aspect G-02 Classifying the decision context as situation A, B, and C for building and product LCA Description The ILCD Handbook distinguishes between different decision contexts for LCA studies. This distinction is part of the goal and scope definition of an LCA study, and has major implications for further definitions of system boundaries and modelling…
