What are carbon offsets?

Question

Options

• ACertificates that represent the payment for some activity that reduces greenhouse gas emissions.
• BNatural gases produced by rainforests which work against the formation of carbon dioxide (CO2).
• CPower generating installations based on natural sources of energy, such as solar panels and windmills.

• A
  87% (41)
• B
  4% (2)
• C
  9% (4)

Explanation

Option A is correct because carbon offsets are tradeable certificates or credits representing a verified reduction (or removal) of one metric ton of CO₂ equivalent - essentially a financial instrument that compensates for emissions produced elsewhere.

Option B is wrong because rainforests absorb CO₂ (they don't produce "natural gases that work against CO₂ formation"), and no such category called "natural gases produced by rainforests" exists in climate science or carbon markets.

Option C is wrong because that describes renewable energy installations, which are a source of clean power - they may generate carbon credits, but they are not carbon offsets themselves.

Memory tip: Think of "offset" like balancing a scale - you emit carbon on one side, and you pay someone to reduce carbon on the other side to balance it out. The certificate is proof that the balancing act happened.
