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.

  • Biomethane ‘green’ gas is growing contender in UK renewable energy market

    The injection of renewable or “green” gas into UK networks has been growing rapidly – and there are now 28 biomethane to grid projects connected to the gas distribution network, transforming food, brewery and agricultural wastes and energy crops into ultra-clean energy. These plants have the capacity to produce 1.8 billion kilowatt hours of gas per year, enough to meet the heating and cooking needs of around 100,000 homes. Biomethane injected into the gas grid, helps decarbonise gas supply in just the same way as renewable electricity decarbonises power generation...
