Gas flares are leaking five times as much methane than previously thought

More lit flares and improved efficiency would be like taking nearly 3 million cars off the road

Flares, like the ones here, burn off the natural gas emitted during oil and gas production, turning methane into less potent carbon dioxide. But the efficiency of these flares is much lower than previously thought.

In many oil and gas producing regions, flames light the sky.
