CAP Footprint Analysis 2

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?

Accepted Answer

225 mt CO2e

Answer

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?

Accepted Answer

Economic allocation

Answer

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?

Accepted Answer

Raw material extraction and end-of-life disposal

Answer

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?

Accepted Answer

Scope 3, Category 7

Answer

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?

Accepted Answer

Nitrous oxide (N2O)

Answer

N2O has a GWP100 of approximately 298, meaning it is 298 times more potent than CO2 over 100 years.
