Although the other GHGs, unit for unit, are much more potent than CO 2 in their effects, the latter is the most important GHG because of its volume. The other problem is that methane is mainly a non-renewable energy supply (found above crude oil) and combustion in general reduces the reserves. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. The Inc omplete Combustion of Natural Gas - Methane.

Dans la réaction de combustion du méthane, il y a toujours deux fois plus de molécules de dioxygène que de molécules de méthane. Ainsi, pour la combustion incomplète du butane, le bilan de la transformation chimique peut s'écrire : Butane + dioxygène = eau + dioxyde de carbone + monoxyde de carbone + carbone 2. Carbon monoxide is a poisonous gas, which is one reason why complete combustion is preferred to incomplete combustion. The combustion of methane, a hydrocarbon. gcsescience.com

A common example of the incomplete combustion of hydrocarbons is the yellow flame of a Bunsen burner. (see complete
Typically, conditions that favor formation of N2O also favor emissions of methane. Combustion is a (unlike the clear blue flame seen in complete combustion). In the complete combustion of methane gas you produce carbon However,the oxidation of methane to soot is generally given as the following: C H X 4 (g) + O X 2 (g) ⟶ C (s) + 2 H X 2 O (g) The incomplete combustion of methane can result in a slew of partially oxidized products, including C O, but also methanol, formic acid, formaldehyde, and higher hydrocarbons also.
