Methane (CH4) and carbon dioxide (CO2) are both Greenhouse Gases, but methane holds in 25 times as much heat as carbon dioxide, so clearly we have to address methane emissions if we can hope to curb climate change! That means dealing with food waste, cattle production, and fracking–all of which release methane. In landfills, rotting organic materials that are buried with no exposure to air are producing methane too. In many places that methane is tapped and burned to provide energy for the needs of the landfill facility. Of course carbon dioxide results from the burning, but that is preferable to allowing the methane to seep into the atmosphere.
