Traceable sustainable biomass.From origin to energy.
GGL develops and maintains reliable and practical certification standards that independently verify sustainable biomass throughout the supply chain, providing transparent, reliable and accessible assurance from origination through to conversion into energy.
Enabling confidence across the biomass supply chain
The transition to renewable energy depends on biomass that is produced, traded and used responsibly. That requires more than good intentions: it requires clear standards, reliable verification and complete traceability.
GGL exists to provide that assurance.
We work with biomass producers, first collectors, traders, energy companies, Certification Bodies and regulators to create a certification system that is practical to implement, rigorous to audit and trusted by the markets it serves.
Practical certification. Credible assurance.
Certification should strengthen confidence, not create unnecessary complexity.
GGL combines robust sustainability requirements with practical implementation, helping organisations demonstrate compliance while supporting efficient international trade.
Our certification provides:
Independent assurance by accredited Certification Bodies.
100% verified traceability from origin through to conversion into energy
Strict yet practical standards
Alignment with regulatory frameworks.
Transparent governance and continuous improvement.
Sustainability you can verify
GGL certification follows biomass through every stage of the supply chain, through its chain of custody and GGLedger™ platform. From the point where biomass is sourced, every transfer is documented, verified and independently audited. This creates a transparent chain of custody that allows sustainability claims to be supported by verifiable evidence. The result is confidence for everyone involved, from biomass producers and traders to energy companies, regulators and end users.

One certification scheme. Multiple markets.
GGL develops and maintains certification standards for sustainable biomass across international supply chains.
Whether organisations operate locally or internationally, GGL provides a consistent framework that supports credible sustainability claims.
Certification you can trust
Confidence builds on integrity, transparency and objectivity.
GGL certification is carried out by accredited, independent Certification Bodies. Compliance is verified through regular audits, transparent requirements and documented evidence.
Every batch of biomass, all transactions across the chain of custody, and all conversions into energy are verified - 100% and ex-ante, - and logged into GGLedger™.
As an independent foundation upholding the highest standards of integrity and objectivity, GGL develops and maintains the certification scheme and works closely with regulators, industry and other stakeholders to ensure it remains practical, relevant and credible.
