Consequential life cycle assessment (CLCA) considering the
impacts from a change in demand for bioethanol in Thailand is
applied to quantify GHG emissions. The approach deals with
market-based cause-effect relationship by identifying what will
happen if we increase the production of the product in question.
CLCA includes marginal (actually affected) suppliers and handles
co-products by expanding the investigated product system to
include the additional functions and their affected processes
related to the co-products (or system expansion)
