Natural gas is a naturally occurring gas that consists of mostly methane. It is used as a source of energy for heating and cooking in the residential setting. Each one hundred cubic feet of gas (ccf) is responsible for 5.312 kg of carbon dioxide emissions.[1] Based on average household consumption in the United States and average household size of 2.58, the annual carbon dioxide emissions per person from natural gas are about 1,580 kg carbon dioxide equivalent (CO2e).[2]


The average residential customer in the United States uses 74.2 million British thermal units (MMBtu), or about 766 hundred cubic feet (ccf), of natural gas every year.[3][4]
