Question 1

The Global Warming Potential (GWP) of a greenhouse gas is measured relative to which reference gas over a 100-year time horizon?

Accepted Answer

Carbon dioxide (CO₂)

Answer

GWP is defined relative to CO₂, which has a GWP of 1 by definition over the 100-year horizon used in most corporate reporting.

Question 2

Which emission factor source is generally preferred when calculating Scope 1 emissions from stationary combustion in the United States?

Accepted Answer

EPA's Mandatory Greenhouse Gas Reporting Rule emission factors

Answer

The EPA's emission factors (published in AP-42 and the Mandatory GHG Reporting Rule) are the most appropriate primary source for US stationary combustion calculations.

Question 3

A logistics company wants to include Scope 3 emissions from third-party trucking contractors. Which calculation method is most data-intensive but most accurate?

Accepted Answer

Supplier-specific method

Answer

The supplier-specific method uses actual activity data and emission factors provided directly by the supplier, making it the most accurate but also most data-intensive approach.

Question 4

What does the term 'emission intensity' mean in the context of an organizational carbon footprint?

Accepted Answer

GHG emissions per unit of economic or physical output

Answer

Emission intensity normalizes GHG emissions against a business metric (e.g., revenue, production units) to enable performance comparisons across different scales.

Question 5

Under ISO 14064-1:2018, what is the term used for the process of checking that GHG inventory data is internally consistent and correctly calculated?

Accepted Answer

Quality control (QC)

Answer

ISO 14064-1 uses 'quality control' to describe internal checks and procedures that ensure data accuracy and consistency before external verification.
