How does IT in general, or more specifically Green IT, help to decrease worldwide carbon emissions?

Question

Options

• AIT is responsible for the operation of large windmill parks.
• BIT reduces the need for transportation.
• CIT uses very little energy.

• A
  2% (1)
• B
  91% (39)
• C
  7% (3)

Explanation

Option B is correct because IT enables remote work, video conferencing, digital document sharing, and e-commerce - all of which reduce the need for people and goods to physically travel, directly cutting transportation-related carbon emissions, which are among the largest contributors to global CO₂ output.

Why the distractors are wrong:

• A is wrong - IT does not operate windmill parks; that's the domain of energy engineering and grid infrastructure. IT may monitor or optimize them, but it doesn't run them.
• C is wrong - IT actually consumes significant energy; data centers alone account for roughly 1–2% of global electricity use. Green IT aims to reduce that consumption, not claim it's already negligible.

Memory tip: Think of Green IT as a travel replacement - every Zoom call that cancels a flight, every e-signature that avoids mailing a document. "Green IT = fewer trips = less fuel burned."
