GGL – Green Gold Label
Green Gold Label (GGL) is an international certification scheme for sustainable biomass. It provides assurance of sustainability and quality throughout the entire supply chain, from production to final use. For organisations in the biomass sector, GGL offers a credible standard to meet client demands. Control Union Certifications performs GGL audits globally, supporting businesses in demonstrating their commitment to sustainability.

What is GGL?
Established in 2002, GGL is one of the world’s pioneering green energy certification schemes for biomass. It covers a wide range of materials, including woody biomass, agricultural residues, and bio-liquids for bio-based products and energy generation. Certification provides demonstrable proof of quality and sustainability, confirmed through independent, annual audits. This allows producers, traders, and generators to meet stringent customer and regulatory requirements with confidence. Control Union offers global expertise in auditing against the GGL standards.
