Carbon dioxide and methane as greenhouse gases
Question
- A. Due to social, economic, and technological factors
- B. Because they are always small
- C. Only due to economic factors
- D. Because they only affect individuals
Answer
The correct option is Due to social, economic, and technological factors. This answer is correct because it matches the approved learning objective to define carbon footprint as the total amount of carbon dioxide and other greenhouse gases emitted over the full lifecycle of a product, service or event in the subtopic The carbon footprint and its reduction.
Explanation
The correct option is Due to social, economic, and technological factors. Due to social, economic, and technological factors is correct because it directly supports the approved learning objective to define carbon footprint as the total amount of carbon dioxide and other greenhouse gases emitted over the full lifecycle of a product, service or event. 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 Definition
Students often define carbon footprint only as the amount of carbon dioxide emitted, ignoring other greenhouse gases.
Remember that a carbon footprint includes the total amount of carbon dioxide and other greenhouse gases emitted over the full lifecycle of a product, service, or event.
