Methane is the second biggest greenhouse gas contributor to climate change. It’s also 84 times more potent than culprit number one, carbon dioxide. Unsurprisingly, 60% of global emissions result from human activity. While reducing methane emissions is key to tackling global warming, removing it from the air has proven challenging. That’s because the gas can be burnt off from air when its concentration exceeds 4%. However, the majority of human-caused emissions are below 0.1%. Now, a research team led by the University of Copenhagen has developed a new method that can remove even low-concentration methane. This could be applied to livestock…
