Methane as a "bridge fuel" is pure propaganda

This is replete with disturbing facts that are not being widely reported.
Perhaps the confusion over the motivation for the latest petroleum war is an unfamiliarity with natural gas, whose main component, methane (CH4), is a potentially worse greenhouse gas than carbon dioxide (CO2). Associated hydrocarbon gases are typically found wherever there is oil, mostly methane (70-90%), with some ethane, propane, butane, and hexane. [2] Combusting at roughly the same temperature of about 2000 °C in air, methane and ethane are sold on as natural gas, considered a better fuel than coal or coal gas. Since both are invisible, odourless gases, the foul-smelling, sulphur-based odorant mercaptan is added to warn about leaks and potential explosions.

After 70 years of interventions in the Middle East, we’re used to the black stuff gushing from the ground, but fighting over an invisible gas is new. Most of us also know about the toxicity of oil and its main refined product, gasoline, yet we readily burn natural gas in our homes for heating and cooking, unaware of the dangers from noxious by-products and leaks. Methane comes with good PR too, thanks to a Madison Avenue style makeover. Brought ashore for the first time to the United Kingdom in 1967 near Hull, North Sea gas was given the more environmentally and commercial friendly “natural gas” moniker to distinguish it from coal gas, which is much dirtier to produce and very unnatural. Customers quickly absorbed the conversion costs for heating and cooking. Celebrity cooks swear by it.

Alas, natural gas is just as dirty and unnatural as coal gas when burned, producing all sorts of toxic waste from incomplete burning, chiefly carbon monoxide, hydrogen sulphide, ammonia, volatile organic components, and particulate matter, as well as carbon dioxide and water vapour. Incomplete burning of methane is bad in the same way that burning any petroleum product is bad. We get the same toxic waste and respiratory damage from burning gasoline, plastic, vinyl, or asphalt, smells not easy to forget. - CounterPunch
