The following information relates to RGGOs issued for biomethane within the registry (Registration Database) operated by Grexel on behalf of the GGCS.

Gas Producers

Gas Producers hold accounts on the GGCS registry where they are issued RGGOs based on the amount of green gas they have produced.

Gas Producers must provide the GGCS robust evidence of their green gas production and independent verification of all their meter readings and GHG calculations.

Gas Producers can transfer RGGOs with other participants and cancel RGGOs for end-use consumers.

Account Holders (Traders)

Organisations with an interest in trading RGGOs or allocating them to end-consumers can open GGCS Trader accounts on the Registration Database. These organisations include gas shippers, gas suppliers, commodity traders, and environmental consultants. Gas consumers who wish to engage more closely with the market may also open Trader accounts.

Trader accounts have the function of receiving RGGOs from Producers and other Trader accounts, transferring RGGOs to other Trader accounts, and cancelling RGGOs for end-use consumers.

Associate Members

Organisations which do not produce green gas nor wish to operate a trading account may particate in the Scheme as Associate Members. They do not have accounts in the GGCS registry, but they become part of our Oversight Panel and may describe themselves as members of the Scheme. Commodity brokers who are restricted from operating trading accounts may wish to become Associate Members, as may owners of gas infrastructure assets who do not trade gas or its related products, but have an interest in how green gas is developing as a sector.

Other

The Scheme works with partners to support the running of their certificate schemes. Participants in those schemes use the GGCS Registration Database, but they are not participants in the Green Gas Certification Scheme.
