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.

  • REA support biomethane inclusion in RTFO development fuel sub-target

    On 20 January 2017 the Renewable Energy Association (REA) responded to the Department for Transport's (DfT) Renewable Transport Fuel Obligation (RTFO) consultation supporting the inclusion of biomethane in a proposed new 'development fuel' sub-target. The REA indicated that while there are many ways of producing low GHG energy for heat and power, there are limited ways of achieving large GHG emissions reductions for Heavy Goods Vehicles (HGV)...

  • Renewable biomethane fuel for HGVs offers opportunity to slash road transport emissions

    CNG Fuels recently announced the launch of renewable biomethane fuel, the most cost-effective and lowest-carbon alternative to diesel for heavy goods vehicles, which offers fleet operators the opportunity to slash emissions. Waitrose, John Lewis, Argos and Brit European long-distance articulated lorries are already using the fuel, which is derived from food waste, independently verified as renewable and sustainable, and approved under the Department for Transport’s Renewable Transport Fuel Obligation (RTFO) scheme...
