What a Guarantee of Origin actually guarantees

A GoO is not a delivery note, and it is not a sustainability certificate. Confusing the two is the most expensive mistake in this market.

Regulation & compliance
Biomethane market, Guarantees of Origin

A biomethane Guarantee of Origin is not a delivery note. It says that a given volume of renewable gas was produced and injected somewhere in Europe, and that the right to claim it now belongs to you. The molecules you burn came from the grid, like everyone else’s.

That book-and-claim logic is what makes cross-border trade possible at all. It also means the value sits entirely in the certificate’s integrity: issued in a recognised registry, transferred by a route both countries accept, cancelled in your name before it expires. Under EN 16325 that window is 18 months — long enough to forget about, short enough to lose money on.

And a GoO is not interchangeable with a sustainability certificate. For BEHG, GEG or ETS claims you need proof of sustainability as well, mass-balanced through the chain. Buying one and assuming it covers the other is the most common and most expensive mistake in this market.
