Moving quickly to cut emissions of methane, a potent greenhouse gas produced by everything from livestock farming to fossil fuel extraction, could slow the rate of the Earth’s warming as much as 30 percent, new research has found. The study found that a full-scale push using existing technologies could cut methane emissions in half by 2030. An all-out push to cut methane emissions would take different forms. It would include clamping down on oil- and gas-related leaks, cleaning up abandoned coal mines, expanding the use of feed supplements for cattle to reduce methane in their belches and broadly deploying technologies to capture emissions from landfills. This approach could prevent a half-degree Fahrenheit of warming by mid-century, which could help avoid serious climate fallout.
