Methane is a powerful greenhouse gas that is more potent than carbon dioxide at heating our atmosphere. Reducing methane emissions – with methods including plugging abandoned or orphaned oil and gas wells, improving agricultural practices, reducing food waste, capturing methane from landfills and coal mines, and repairing leaks in oil and gas infrastructure – is critical, but these efforts alone may not be enough. As a result, scientists have begun exploring ways to remove methane directly from the air.
