Question

question 19 4 pts which of the following is not correct about life cycle assessment (lca)? life cycle stages include raw material sourcing, manufacturing & packaging, distribution, use, and end of life the bulk of energy consumption during a cell phones life cycle occurs during its use with consumers lca evaluates the environment impact of a product or process through its entire life cycle lca is a data intensive process, made possible with the use of databases and software common categories of assessed environmental impacts include energy consumption, climate change, water consumption, and toxicity, among others

Explanation:

1. Analyze each option:

• Option 1: Life cycle stages of LCA typically include raw material sourcing, manufacturing & packaging, distribution, use, and end - of - life. This is correct.
• Option 2: For a cell phone, the bulk of energy consumption in its life cycle is actually during the manufacturing (production) stage, not the use stage. So this statement is incorrect.
• Option 3: The core definition of LCA is to evaluate the environmental impact of a product or process throughout its entire life cycle. This is correct.
• Option 4: LCA requires a large amount of data, and databases and software are used to support this data - intensive process. This is correct.
• Option 5: Common environmental impact categories in LCA include energy consumption, climate change, water consumption, and toxicity. This is correct.

Answer:

The option that is not correct about life cycle assessment (LCA) is: "The bulk of energy consumption during a cell phone's life cycle occurs during its use with consumers"
