What is methane leakage? When natural gas escapes before anyone burns it

Natural gas is mostly methane. Burn it, and the main climate problem is CO₂. Let it escape before combustion, and you release methane itself—a greenhouse gas far more powerful over the near term. That means a leaking valve, an open vent, a badly performing flare, or an abandoned well can change the climate footprint of gas before the fuel has produced a single useful kilowatt-hour.
