Phase 0 is the preparatory phase and scope definition.
As stated in the goal and scope definition, this work focuses on the primary energy demand, climate change, and water.
LCA consist of four stages: (1) goal and scope definition, (2) inventory analysis, (3) impact assessment, and (4) interpretation.
LCA consists of four main steps – goal and scope definition, inventory analysis, impact assessment and interpretation [74].
These stages are based on ISO 14040 and 14044 frameworks: the goal and scope definition, the inventory analysis, the life cycle impact assessment and interpretation.
It sums up current practices in terms of goal and scope definition, life cycle inventory (LCI) and life cycle impact assessment (LCIA).
According to EN ISO 14040 2006, LCA is divided into four steps: goal and scope definition, inventory analysis, impact assessment, and finally, interpretation.
That is why the underlying data have been confirmed regarding completeness and consistency with the requirements defined in the goal and scope definition.
The issues or challenges with respect to the four steps of LCA (i.e. goal and scope definition, life cycle inventory, life cycle impact analysis, and interpretation) have been examined and investigated.
To deliver what was previously planned, three main drivers must be in place: quality of the scope definition; alignment of the business strategy; and operability of the asset delivered.
To overcome the limits related to the goal and scope Definition that have emerged from the literature, the activity portfolio concept was introduced along with the control and influence approach, according to ISO 14001.
