Metan is a colorless, odorless gas that is the primary component of natural gas. It is a simple hydrocarbon with the chemical formula CH4, consisting of one carbon atom and four hydrogen atoms. Metan is produced through both natural processes, such as the decomposition of organic matter, and human activities, including fossil fuel extraction. Metan is an important energy source and is used for heating, electricity generation, and as a fuel for vehicles. However, it is also a potent greenhouse gas, with a much higher heat-trapping ability than CO2 over a short time frame, contributing to climate change when released into the atmosphere.
