facilitated via the ERGaR platform
Role of ERGaR
ERGaR serves as the European association for all stakeholders involved in renewable gas (certificate) trading and operates the system that supports cross-border exchange of renewable gas certificates.
ERGaR is the Brussels-based, Europe-wide association for all players involved in the renewable gas market: national biomethane registries, gas network operators, traders and other related organisations. We provide a collaborative, independent and transparent forum where stakeholders come together to shape and support the development of a pan-European renewable gas market.
Since 2021, ERGaR has operated the Certificates of Origin (CoO) Scheme, allowing registries to exchange biomethane certificates across borders through its Cert-X Europe platform. Over 8 TWh of certificates have already been transferred via the ERGaR CoO Scheme.

Brussels, January 2026 ERGaR sees the upcoming Renewable Energy Directive (RED IV) as a decisive moment for Europe’s biomethane sector. The current EU certification framework was not designed specifically for biomethane and has led to fragmentation, duplication, and unnecessary administrative complexity across Member States. ERGaR calls on RED IV to introduce a dedicated biomethane certification…
Co-digestion of biomethane needs fair carbon-intensity accounting
Brussels, January 2026 Across Europe, greenhouse gas (GHG) values for biomethane produced from multiple feedstocks (co-digestion) are currently calculated using different approaches. Some systems apply a single averaged GHG value to all biomethane produced, while others allow feedstock-specific GHG values. This lack of consistency creates uncertainty for producers and the market. With the review of…
