May 22, 2023 · The number-two cause of climate change is methane, the main part of natural gas. Methane reflects about 100 times as much heat as CO 2, but its lifetime in the atmosphere is much shorter: about 10 years. Methane is an especially hard greenhouse gas to measure, because most emissions don’t come from industrial plants.
How much does natural gas contribute to climate change …
Jul 17, 2023 · But recent research suggests those emissions reductions are inflated, thanks to another, more potent greenhouse gas associated with natural gas: methane.
Jul 29, 2014 · Pipeline quality natural gas is composed of over 90 percent methane (CH4), roughly 1.4 percent1 of which is vented routinely or leaked unintentionally from various sources throughout the natural gas supply chain. Methane is a relatively potent greenhouse gas (GHG).

Understanding Greenhouse Gas Emissions from Natural Gas
In 2022, net U.S. greenhouse gas (GHG) emissions were 5,489 million metric tons of carbon dioxide (CO2) equivalent (MMTCO2e). Gross U.S. greenhouse gas emissions from sources only were 6,343 MMTCO2e in 2022.
Natural gas, gas utilities, and the delivery infrastructure are essential to meeting our nation’s greenhouse gas (GHG) emissions reduction goals, including pathways to achieve net-zero emissions.

Natural gas - Wikipedia
Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes. Traces of carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. [2] .
