Methane is a significant greenhouse gas, and it is responsible for around 16% of global greenhouse gas emissions. This potent gas is released during the production and transport of coal, oil, and natural gas, as well as from livestock and other agricultural practices, land use, and the decay of organic waste in landfills.

Methane's impact on climate change is particularly pronounced because it has a much higher global warming potential compared to carbon dioxide over a short time frame. While carbon dioxide is the most prevalent greenhouse gas and has a larger overall contribution to climate change due to its volume in the atmosphere, methane's potency makes it a critical target in efforts to address and mitigate global warming. Additionally, nitrous oxide and CFCs, while also contributing to greenhouse gas emissions, account for smaller percentages in comparison to methane. Thus, methane stands out as a major contributor that should be addressed to effectively combat climate change.
