Question 1
Which phase of a Life Cycle Assessment (LCA) involves defining the goal and scope,
including the system boundary and functional unit?
A. Inventory Analysis
B. Impact Assessment
C. Goal and Scope Definition
D. Interpretation
Correct Answer: C
Explanation: The Goal and Scope Definition phase is the first and most critical step, as it
sets the foundation and boundaries for the entire study.
Question 2
In LCA, what is the term for the quantified description of the system being studied,
which defines its function and provides a reference for inputs and outputs?
A. System Boundary
B. Functional Unit
C. Allocation Procedure
D. Cut-off Criteria
Correct Answer: B
Explanation: The functional unit is a measure of the function of the studied system and
provides a reference to which the inputs and outputs can be related.
,Question 3
A researcher is conducting an LCA on a new type of concrete. They decide to exclude
the production of the cement kiln dust, arguing it is a waste product. This is an example
of applying:
A. System Expansion
B. Cut-off Criteria
C. Allocation
D. Sensitivity Analysis
Correct Answer: B
Explanation: Cut-off criteria are used to exclude specific inputs or outputs from the
system if they are deemed insignificant in terms of mass or environmental impact.
Question 4
Which of the following is NOT a mandatory element of the Life Cycle Inventory (LCI)
analysis phase?
A. Data collection
B. Data validation
C. Relating data to the functional unit
D. Developing a social impact score
Correct Answer: D
Explanation: LCI is focused on environmental flows. Social impact assessment is
typically part of Social LCA (S-LCA), not the standard environmental LCI.
Question 5
When a process produces multiple outputs (e.g., a refinery producing gasoline and
diesel), LCA practitioners must use ____________ to assign the environmental burdens
between the co-products.
,A. System Expansion
B. Allocation
C. Consequential Modeling
D. Attributional Modeling
Correct Answer: B
Explanation: Allocation is the process of partitioning the input or output flows of a
process or a product system between the product system under study and other
product systems.
Question 6
A company is performing an LCA on a new laptop. They include the extraction of raw
materials, manufacturing, transportation to the consumer, and use phase over a 4-year
lifespan. They decide to exclude the end-of-life disassembly, stating it is uncertain. This
is a violation of which key principle of LCA?
A. Completeness
B. Accuracy
C. Consistency
D. Transparency
Correct Answer: A
Explanation: The principle of completeness requires all relevant inputs and outputs of a
system to be included. Arbitrarily excluding a life cycle stage without justification harms
completeness.
Question 7
Which impact assessment method focuses on the potential for a substance to
contribute to acidification, often expressed in units of kg SO2-equivalent?
A. Eutrophication Potential
B. Ozone Depletion Potential
C. Acidification Potential
, D. Photochemical Ozone Creation Potential
Correct Answer: C
Explanation: Acidification Potential (AP) measures the potential of acidifying pollutants
like SO2 and NOx to cause acid rain, with SO2 as the reference substance.
Question 8
The "system boundary" in an LCA defines:
A. The geographical location of the study.
B. The set of processes and flows that are included in the product system.
C. The time horizon for the assessment.
D. The specific product being analyzed.
Correct Answer: B
Explanation: The system boundary is a critical part of the goal and scope definition,
delineating what is included and excluded from the LCA.
Question 9
A "cradle-to-gate" LCA includes all processes from:
A. Raw material extraction to the factory gate.
B. Raw material extraction to the end-of-life.
C. The factory gate to the end-of-life.
D. The point of sale to the point of disposal.
Correct Answer: A
Explanation: Cradle-to-gate covers the life cycle stages from resource extraction
(cradle) up to the point where the product leaves the manufacturing facility (gate).
