Methane (CH4) is a potent greenhouse gas, trapping heat 20 times more effectively than carbon dioxide and significantly contributing to climate change. It’s produced through both natural and human activities. Natural sources of methane include wetlands, oceans, and other sources. Human activities that produce methane include the burning of fossil fuels, waste management, and more than half of it: the raising of livestock. Methane is also produced as a by-product of specific industrial processes.
