Gas leaks in Boston

Methane is a greenhouse gas. Many times worse than carbon dioxide. Around 120 times. Being combustible, it doesn't persist long in the atmosphere. It combines with oxygen to form carbon dioxide, which still isn't good — just less bad.
Methane is the major component of natural gas. One use of natural gas is domestic heating & cooking. It gets to homes through pipes laid in the ground. As the pipes age, they start to leak. This is not normally a fire risk. But we don't want methane in the atmosphere.
Google & Environmental Defense Fund have co-operated in a pilot project to fit methane sensors to 3 Street View cars.
