No it doesn't.

I don't know if this also applies
to the methane put in buses.

Well, since it doesn't apply to domestic gas,
it's a pointless point.

You seem to be trying to point-score rather than educate. A quick web search
suggests that some gas suppliers add H2S, and others add mercaptan, which is
another egg-smelling sulphur compound. Either way, burning it will produce
SO2.
