Question 1

Which greenhouse gas has the highest 100-year Global Warming Potential (GWP) among those commonly tracked in carbon audits?

Accepted Answer

Sulfur hexafluoride (SF₆)

Answer

SF₆ has a 100-year GWP of approximately 23,500, making it the most potent GHG commonly tracked under the Kyoto Protocol basket.

Question 2

In life cycle assessment (LCA), which phase typically contributes the most to the carbon footprint of a manufactured steel product?

Accepted Answer

Raw material extraction and processing

Answer

For steel, raw material extraction and the energy-intensive smelting process (especially blast furnace operations) dominate the product's lifecycle carbon emissions.

Question 3

What does the concept of 'carbon sequestration' refer to in environmental impact assessments?

Accepted Answer

The process of capturing and storing atmospheric CO₂

Answer

Carbon sequestration is the long-term capture and storage of atmospheric CO₂ in reservoirs such as forests, soils, oceans, or geological formations.

Question 4

A company's Scope 3 emissions include which of the following?

Accepted Answer

Business air travel by employees

Answer

Employee business travel is a Scope 3 Category 6 emission because it occurs in assets not owned or controlled by the reporting company.

Question 5

Which land-use change activity is a major contributor to global greenhouse gas emissions according to the IPCC?

Accepted Answer

Deforestation of tropical rainforests

Answer

Tropical deforestation releases enormous amounts of stored carbon and eliminates carbon sinks, making it one of the largest land-use emission sources globally.
