Methane is CH4. It doesn't degrade to CO2 so much as the relative ability to trap infrared radiation is given in proportion to what an equal number of CO2 molecules would absorb/trap. Similarly, other gasses like refrigerants are rated in Global Warming Potential (GWP) units based on 20 years of absorption of infrared. https://en.m.wikipedia.org/wiki/Atmospheric_methane https://en.m.wikipedia.org/wiki/Atmospheric_methane https://en.m.wikipedia.org/wiki/Global_warming_potential https://en.m.wikipedia.org/wiki/Global_warming_potential
