Which statement about secondary carbon footprint is correct?

Which statement about secondary carbon footprint is correct?

• A. It measures direct emissions from fossil fuels
• B. It measures indirect CO2 from products we use e.g. from foods we eat
• C. It measures water usage
• D. It measures carbon credits

Answer: (B)

Secondary carbon footprint looks at the indirect CO2 emissions tied to the goods and services we use—the emissions embedded in making, transporting, and delivering products, like the foods we eat. This is why describing it as indirect CO2 from the products we use is the correct choice: it captures the whole supply chain behind the items we consume, not just what we personally burn or emit. Direct emissions from fossil fuels come from our own activities (like heating or driving) and are not part of the secondary footprint. Water usage isn’t a carbon measure, and carbon credits relate to offsetting emissions rather than measuring the footprint itself.
