3,000 Gas Leaks in Boston

Nathan Philips and colleagues published  a study that identifies 3,356 separate natural gas leaks under its the streets of Boston from its aging natural-gas pipeline system.  Several of these locations show gas concentrations exceeding the threshold above which explosions can occur.  These types of fugitive emissions also are important because pound for pound, the comparative impact of CH4 on climate change is over 20 times greater than CO2 over a 100-year period.
