Which emissions concern accompanies natural gas?

  • A.Unburnt methane escaping as a greenhouse gas
  • B.None, since methane is harmless and its escape therefore presents no environmental concern of any kind
  • C.Only smell
  • D.Methane slip from incomplete combustion or leakage, which is a far more potent greenhouse gas than carbon dioxide

Answer: A

Methane is many times more potent than carbon dioxide as a greenhouse gas. The last option explains exactly why slip matters, which makes it a correct and more instructive version of the same answer. The order in which the effects act is what decides the outcome, so it is worth establishing first. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. Reading the definition literally, rather than recalling a summary, avoids the usual confusion.
