The Green Gas Certification Scheme

The Green Gas Certification Scheme (GGCS) tracks biomethane, or ‘green gas’, through the supply chain to provide certainty for those that buy it.

Each unit of green gas injected into the grid displaces a unit of conventional gas. So the GGCS tracks each unit of green gas from its injection into the distribution grid, to any trades, to its sale to a consumer, or group of consumers. It tracks the contractual rather than physical flows to ensure there is no double-counting from production to end use.

The GGCS is run by the Renewable Energy Association’s subsidiary, Renewable Energy Assurance Ltd. GGCS participants oversee the way it is run, on a not-for-profit basis.
