Calling on National Grid to fix 261 gas leaks in Town
The Sustainable Wellesley action was part of a larger effort across the Boston metropolitan area led by Mothers Out Front, the Gas Leaks Allies, and other environmental groups frustrated by the lack of progress on gas leaks. In Boston, more than 100 protesters gathered on Cambridge Street near a 13-year old leak. Activists are particularly concerned that National Grid has backed away from its previous commitment to identify and repair the largest volume leaks, sometimes called “super-emitters.” These large volume leaks make up only about 7 percent of the more than 16,000 leaks in the state but they emit roughly 50 percent of the methane. The other large gas companies — Eversource and Columbia Gas — have already begun using the accepted method for identifying and repairing these leaks, while National Grid has said it will not do so until next year.
