Which statement describes a secondary carbon footprint?

Which statement describes a secondary carbon footprint?

• A. Measures indirect CO2 from the products we use
• B. Measures direct emissions of CO2 from burning fossil fuels
• C. Measures CO2 from agriculture
• D. Measures emissions from energy generation only

Answer: (A)

The idea here is that a secondary carbon footprint covers the indirect CO2 emissions linked to the goods and services we use, rather than the emissions we generate directly. So when we buy and use products, the manufacturing, transport and energy used to produce those products add CO2 to the atmosphere even before we use them, and that embedded, indirect CO2 is what the secondary footprint measures. That’s why the statement about indirect CO2 from the products we use is the best description. Direct emissions from burning fossil fuels are part of the immediate footprint, not the secondary one; CO2 from agriculture is a specific sector, not the general concept of embedded emissions in products; and emissions from energy generation only narrows the scope too much to describe the broader secondary footprint.
