What is Green Gas?
Green Gas from ENGIE is sourced from generation plants that produce biogas from anaerobic digestion or landfill waste gas. Biogas produces at least 46% less carbon emissions than standard natural gas, enabling you to reduce your carbon footprint. Buying Green Gas is a powerful demonstration of your commitment to sustainable energy sourcing.
All Green Gas supplied by ENGIE is sourced from within the UK, helping to support the UK’s energy independence. Buying Green Gas also supports the local economy where the biomethane plant is located, since the organic matter required for biogas production must be sourced locally, and by-products from the process can be supplied to agricultural and other sectors as fertiliser.
How our Green Gas is produced
Green Gas certification
Every kWh of Green Gas supplied by ENGIE comes with a Renewable Gas Guarantee of Origin (RGGO), which identifies exactly where, when, and how it was produced. This gives you complete traceability and assures you that your gas comes from authentic biogas sources.
ENGIE itself is a registered supplier with the Green Gas Certification Scheme (GGCS). This certification means that every Green Gas contract we sign is registered with the scheme administrator, a subsidiary of the Renewable Energy Association. Certified gas is tracked from its injection into the network to its sale to consumers, ensuring there is no double counting and providing certainty for businesses that buy Green Gas.
