Flag question 
use the ISO 14040-2006 to match the following definitions related to the Principles of LCA: 
Due to the complexity ot an LCA, transparency is an impoäant guiding principle to ensure proper interpretation ot results. 
LCA considers the entire lite cycle ot a product, trom raw material extraction and acquisition, through energy and material production and 
manufacturing, to use and end of lite treatment and final disposal. 
Decisions within an LCA are preferably based on natural science. IF this isn't possible, then other scientific approaches (such as social or 
economics) should be applied. 
LCA addresses the environmental aspects and impacts of a product system. Economic and social aspects are, typically, outside the scope of the 
LCA. 
The individual phases of an LCA use the results ot other phases. T ne iterative approach within and beüeen phases contributes to the 
comprehensiveness and consistency ot the study. 
LCA is a relative approach that is structured around a functional unit. The functional unit (tu) defines what is being studied. All analysis are 
relative to the tut 
LCA considers all attributes or aspects ot the natural environment, human health, and resources. As such, possible trade-otts can be identified 
and assessed.

Flag question 
In reading ISO 14044:2006 answer the following related to system boundaries. (wrong answers receive negative marks) 
It is helpful to describe the system using a process flow diagram snowing the unit processes and their inter-relationships. Each unit process should be initially described to define:
