Question

Options

• ATravelling to the office.
• BOpening a spreadsheet.
• CRecycling a server.
• DPrinting out a report.

• A
  1% (1)
• B
  12% (8)
• C
  81% (55)
• D
  6% (4)

Explanation

Recycling a server falls under the secondary footprint because it relates to the lifecycle of a product - specifically its end-of-life disposal phase - which generates indirect carbon emissions through processing, transportation to recycling facilities, and material recovery. The secondary footprint covers emissions tied to the manufacture, use, and disposal of goods and services we consume, not our direct energy burning.

Why the distractors are wrong:

• A (travelling to office) - Direct fuel combustion from transport is a classic primary footprint activity.
• B (opening a spreadsheet) - This draws electricity directly from the grid, making it a primary footprint action tied to real-time energy use.
• D (printing a report) - Powering a printer and consuming paper both involve direct energy use, placing this in the primary footprint.

Memory tip: Think of the primary footprint as what you do (burn fuel, use power right now), and the secondary footprint as what you own or consume (the stuff made for you, delivered to you, or disposed of on your behalf). A server being recycled is about a product's end-of-life journey - not your direct energy use.
