Biogenic methane is a type of methane gas produced by the natural decomposition of organic matter by microorganisms, particularly in anaerobic (low-oxygen) environments. This process occurs in places like wetlands, rice paddies, and landfills, where bacteria break down plant and animal materials, releasing methane as a byproduct. This gas is a significant component of the global methane emissions and plays a role in the greenhouse effect, contributing to climate change. Unlike fossil fuel-derived methane, biogenic methane is considered renewable, as it is generated from biological processes that can be replenished over time.
