Green Gas Certificate Sales Reach 1 TWh

14 November 2017 |

Sales of certificates from the Green Gas Certification Scheme (GGCS) have reached 1 TWh, demonstrating the increasing demand from businesses to address their Scope 1 emissions with renewable power.

The GGCS enables the tracking of biomethane (“green gas”) from landfill gas and anaerobic digestion facilities that inject green gas directly into the gas grid. Global disclosure platform CDP recognises the purchase of green gas certificates, which under the GGCS are called Renewable Gas Guarantees of Origin (RGGOs), as a credible means for businesses with operations in the UK to report lower Scope 1 emissions and make 100% renewable gas claims.

Natural Capital Partners’ Chief Product Officer, Oliver Crouch, commented: “1 million MWh is a significant milestone for this emerging market to reach. This rapid growth has been facilitated by CDP’s guidance which encourages companies to extend the market-based reporting approach from renewable electricity to renewable gas. Businesses like Sopra Steria are taking advantage of this opportunity to include green gas as part of their energy mix today.”

With 41 producers in the UK and rising, the green gas market has significant scope to develop. In fact, a recent study suggested the potential for renewable gas production could hit 149 TWh by 2050.

The GGCS is seeing a fourfold increase in demand year on year. Dr. Kiara Zennaro, Head of Biogas at the Renewable Energy Association said: “We’ve seen huge growth in the green gas sector since 2010 and the success of this scheme is both exciting and essential. 1 TWh of sales is a great sign that this industry is maturing.”

We are pleased to offer clients this cost-effective solution to drive down Scope 1 emissions, alongside our portfolio of Energy Attribute Certificates for Scope 2 emissions. To discuss how RGGOs can help reduce your business’ Scope 1 emissions, please contact us.
