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.

  • Committee on Climate Change highlights role of green gas in reducting emissions from buildings

    The Committee on Climate Change (CCC), the statutory body that advises the Government on their progress towards carbon targets, released its ninth annual assessment last week. There was positive news on reductions to date (42% since 1990) but concern over the policy landscape that will keep the UK moving the right direction. The report includes a target of 20TWh per annum of biomethane-to-grid by 2030, helping to support a 20% reduction in emissions from buildings. This a 16GWh increase from the appox. 4TWh currently built. You can download the full CCC report here...
