Methane is a group-14 hydride and the simplest alkane. It consists of one carbon atom covalently bonded to four hydrogen atoms, giving it a tetrahedral structure.

Second, the sources and abatement strategies for methane differ radically from those of CO2, demanding a tailored market mechanism. CO2 emissions largely stem from combustion in power and transport—centralized, measurable, and with relatively high abatement costs. Methane, by contrast, is fugitive: it leaks from oil and gas wells, pipelines, coal mines, landfills, rice paddies, and livestock enteric fermentation. Many of these sources are diffuse, variable, and notoriously difficult to monitor. However, they also offer extremely low-cost abatement opportunities—in many cases, capturing a ton of methane pays for itself via the sale of natural gas (the “green completion” method). An METF-CH4 would be designed to unlock these low-hanging fruits. It would require mandatory monitoring, reporting, and verification (MRV) using emerging technologies like satellites (e.g., MethaneSAT) and continuous monitors. By creating a price on pure methane, the framework would make it profitable for a landfill operator to install a gas capture system or for a farmer to adopt aerobic rice irrigation and feed additives for cattle—solutions that are economically marginal under current CO2e prices but become viable under a dedicated methane price.

Another critical pathway is the conversion of methane to methanol, a liquid that is one of the world's most widely used chemical feedstocks. This process typically involves an : first, methane is converted into synthesis gas (syngas, a mix of CO and H₂) via steam reforming, and then the syngas is catalytically converted into methanol. Emerging innovations are streamlining this process. Companies are developing modular, low-cost systems that repurpose automotive engines to function as mini chemical plants, converting methane gas directly into liquid methanol on-site at landfills or farms. This eliminates the need for expensive pipeline infrastructure.
