AICE Environmental Management Paper 2 Practice Exam

Life-cycle analysis is best described as:

A process for calculating only energy use during production A method for labeling products with recycling instructions A system for managing municipal waste streams An environmental tool that tracks impacts across a product’s entire life cycle

Correct Answer:

An environmental tool that tracks impacts across a product’s entire life cycle

Explanation:

Life-cycle analysis examines the environmental impacts of a product or service across every stage of its life, from raw material extraction through manufacturing, distribution, use, and end-of-life disposal or recycling. It collects data on energy use, resource depletion, and emissions at each step and groups them into impact categories like global warming potential, acidification, eutrophication, and water use. The goal is to compare options and find where changes can most reduce the overall environmental burden, rather than just looking at energy use during production or managing waste streams. It’s not about labeling recycling instructions and it isn’t a waste-stream management system.
