Boston’s leaky pipes add to greenhouse-gas buildup
A Harvard-led study reveals that an aging natural-gas distribution system short-changes Boston-area customers and contributes to greenhouse-gas buildup. Depending on the season, natural gas leaking from the local distribution system accounts for 60 percent to 100 percent of the region’s emissions of methane.
