Methane

Flaring

Combustion of a gas stream in a device designed to burn it.

Methane

Fossil methane

Methane originating from carbon stored in geological deposits over long periods.

Methane

Fugitive emissions

Unintended releases of gas from equipment, infrastructure or other sources.

Methane
