Which of the following best illustrates the inclusion of indirect emissions in a product’s carbon footprint?

The correct option is Measuring the CO₂ released during the product’s transport to the retailer. Measuring the CO₂ released during the product’s transport to the retailer 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.
