I assume the methane would be the fuel, not the byproduct.

  I imagine you won't combust 100% of the fuel. So wouldn't it be both.

    Pure methane is a bunch of molecules with just one carbon, which simplifies things a bit vs. a cracked and heterogeneous mix of longer chain (10+) molecules. You can incompletely combust a 10-carbon molecule and wind up with other hydrocarbons but if you burn up CH4, you're definitely just getting one CO2.
