Biomethane Guarantees of Origin trading platform

Why biomethane GoOs are different from electricity GoOs

Biomethane Guarantees of Origin look like electricity GoOs on the surface — both are tradable certificates that prove a renewable attribute. They differ in three ways that matter to a trading desk. First, biomethane GoOs carry sustainability characteristics: feedstock category, country of origin, GHG savings — and a buyer that needs an Annex IX-A claim cannot use a GoO backed by Annex IX-B feedstock. Second, the EU biomethane registry landscape is fragmented: gdogas.es, Nabisy, the GSE registry, Vertogas and others each have their own data models, with the AIB providing the hub that maps between them. Third, biomethane GoOs are increasingly being used for RED III, FuelEU Maritime and CSRD compliance — meaning the audit standard is higher than for typical green-electricity trades.

GooClear was built for that complexity. The platform attaches every relevant sustainability attribute to every GoO, validates buyer eligibility at trade time and reconciles registry-side retirements back to the trade so the audit trail is closed by the time the receipt arrives.

What a clean trade looks like on GooClear

A biomethane GoO trade on GooClear is six steps. The seller lists the volume with full sustainability characteristics from their mass balance. The buyer searches by characteristic — feedstock category, country, vintage, GHG range — and either lifts the offer or sends a counter. Funds are committed via SEPA Instant. The GoO is transferred in the seller's national registry to the buyer's holding account. If the buyer's registry of cancellation is in a different country, the cross-border transfer is routed through the AIB hub. The cancellation receipt is pulled back and attached to the trade record. Both sides get the audit evidence in the same place.

End-to-end, this typically takes minutes once the counterparty relationship is established — versus the days of email back-and-forth that bilateral GoO trades still require on most legacy setups.

Who trades on GooClear

We deliberately keep the platform open to every link of the value chain so liquidity concentrates instead of fragmenting across counterparty-specific portals.

• Biomethane producers selling forward production or spot from accumulated mass-balance position.
• Traders and utilities sourcing certified GoOs to fulfil mandate, voluntary or bunker demand.
• Industrial offtakers — steel, cement, glass, chemicals — meeting CSRD-aligned Scope-1/Scope-2 targets.
• Maritime bunkering operators and logistics fleets meeting FuelEU Maritime obligations.
• Aggregators bundling biomethane GoOs with PPA renewable-electricity GoOs for corporate buyers.

Compliance the way the auditor wants it

Every trade on GooClear leaves an audit trail the regulator can verify. The mass-balance position before and after issuance is hash-pinned. The voluntary-scheme certificate, GHG calculation methodology and feedstock origin documents are attached to the GoO and travel with it through every transfer. The national registry's cancellation receipt is the canonical close-out artefact and is fetched automatically. There is no separate 'audit pack' to produce; the audit trail is the trading record.
