Leaky Pipes Are a Fixable Climate Threat

摘要

An invisible, underappreciated source of greenhouse gases is right in America's front yards: leaking pipes that carry gas into people's homes. The good news is scientists have devised a clever way to find these leaks by attaching methane detectors to car bumpers-they've used Google Street View photography cars-and driving along city streets. It's a strategy that natural gas utilities should use to monitor their networks and seal the biggest leaks.
