Question
What factors can influence the objectivity of a life cycle assessment (LCA)?
Answer
Factors that can influence the objectivity of an LCA include the assumptions made during the assessment, the selection of data sources, and potential biases in interpreting the results. Additionally, value judgments may affect how environmental impacts are quantified and compared.
Explanation
This question tests the understanding of the complexities involved in conducting a life cycle assessment and the potential for subjective influences. It requires students to think critically about the assessment process and the implications of bias.
Common mistake
Misunderstanding Objectivity in LCA
Students often think that life cycle assessments (LCAs) are completely objective and free from bias.
Emphasize that LCAs can involve subjective value judgments and may not account for all environmental impacts equally.
