Methane, the major element of natural gas, is more harmful to the environment than CO2. The Environmental Protection Agency has assigned methane gas a Global Warming Potential (GWP) of 72 (20 year average). That means it is ”72 times more effective at preventing infrared radiation from escaping the planet.”
Natural gas production and use comes right after landfills as the chief source of methane gas.
