CAP Footprint Analysis 2 — Questions and Answers
Question 1: A manufacturing company purchases 500 MWh of electricity from a grid with an emission factor of 0.45 kg CO2e/kWh. What is the Scope 2 emission in metric tons CO2e?
- 225 mt CO2e (Correct answer)
- 2,250 mt CO2e
- 22.5 mt CO2e
- 0.225 mt CO2e
Correct answer: 225 mt CO2e
500 MWh × 1,000 kWh/MWh × 0.45 kg CO2e/kWh = 225,000 kg = 225 mt CO2e.
Question 2: Which allocation method distributes upstream emissions proportionally to the economic value of co-products?
- Economic allocation (Correct answer)
- Mass allocation
- System expansion
- Causal allocation
Correct answer: Economic allocation
Economic allocation assigns emissions based on the relative market value of each co-product.
Question 3: In a product carbon footprint (PCF) study, what does the 'gate-to-gate' system boundary exclude?
- Raw material extraction and end-of-life disposal (Correct answer)
- Manufacturing processes only
- Transportation between facilities
- Energy consumption at the factory
Correct answer: Raw material extraction and end-of-life disposal
Gate-to-gate covers only the manufacturing stage, excluding upstream raw material extraction and downstream end-of-life phases.
Question 4: Under the GHG Protocol, which category covers employee commuting emissions?
- Scope 3, Category 7 (Correct answer)
- Scope 2, Category 2
- Scope 1, Category 1
- Scope 3, Category 4
Correct answer: Scope 3, Category 7
Employee commuting is classified as Scope 3, Category 7 under the GHG Protocol Corporate Value Chain Standard.
Question 5: Which gas has a 100-year Global Warming Potential (GWP) of approximately 298, making it a potent greenhouse gas despite low atmospheric concentrations?
- Nitrous oxide (N2O) (Correct answer)
- Methane (CH4)
- Sulfur hexafluoride (SF6)
- Carbon dioxide (CO2)
Correct answer: Nitrous oxide (N2O)
N2O has a GWP100 of approximately 298, meaning it is 298 times more potent than CO2 over 100 years.
Question 6: A retailer wants to report Scope 3 emissions from sold products. Which data collection approach is most accurate?
- Primary data from supplier emission inventories (Correct answer)
- Industry-average emission factors from databases
- Spend-based emission factors
- Revenue-weighted averages
Correct answer: Primary data from supplier emission inventories
Primary data collected directly from suppliers provides the most accurate basis for Scope 3 Category 11 (use of sold products) reporting.
Question 7: Which ISO standard specifically addresses the quantification and communication of greenhouse gas emissions for organizations?
- ISO 14064-1 (Correct answer)
- ISO 14040
- ISO 14001
- ISO 50001
Correct answer: ISO 14064-1
ISO 14064-1 provides principles and requirements for quantifying and reporting organizational greenhouse gas inventories.
