Carbon dioxide and methane as greenhouse gases
Question
- A. The CO₂ released when a product is manufactured
- B. The CO₂ emitted from the electricity used to power a factory
- C. The CO₂ stored in the raw materials before they are processed
- D. The CO₂ emitted when a product is disposed of in a landfill
Answer
The correct option is The CO₂ emitted from the electricity used to power a factory. This answer is correct because it matches the approved learning objective to explain that a carbon footprint can include direct and indirect emissions in the subtopic The carbon footprint and its reduction.
Explanation
The correct option is The CO₂ emitted from the electricity used to power a factory. The CO₂ emitted from the electricity used to power a factory is correct because it directly supports the approved learning objective to explain that a carbon footprint can include direct and indirect emissions. This belongs to the subtopic The carbon footprint and its reduction within Carbon dioxide and methane as greenhouse gases, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The carbon footprint and its reduction.
Common mistake
Misunderstanding Carbon Footprint Components
Students often think that a carbon footprint only includes direct emissions from burning fossil fuels.
Emphasize that a carbon footprint includes both direct emissions (like those from transportation) and indirect emissions (such as those from the production and transportation of goods).
