Fossil fuel use may emit 40 percent more methane than we thought

The finding could help in targeting how and where to reduce this climate-warming gas

gas burning

Using fossil fuels releases much more of the potent greenhouse gas methane than previously thought — possibly 25 to 40 percent more, new research suggests.
