The Roundtable on Sustainable Biomaterials is an international initiative, which develops and implement the RSB Global Sustainability Standard, a global standard for sustainable production, conversion and use of biomass. The RSB Standard is de to demonstrate sustainable production of all derivatives from biomass, including biofuels, bioenergy, bio-plastics, bio-packaging, food additives, bio-chemicals, etc.

More than 100 organizations from 30 countries representing all sectors are registered RSB members and participate in the development and implementation of the RSB Standard and Certification System. Participation in the RSB is open to any organization working in a field relevant to biomass and biomaterials. The RSB is a Full Member of the International Social and Environmental Accreditation and Labelling Alliance (ISEAL) and is compliant with ISEAL code of conduct for setting social and environmental standards.

To become a RSB Certified Operator you must pass the application and audit stage to display the RSB Certification Mark. Since March 23, 2011, the RSB certification system is open for business. In July 2011, the RSB received the recognition of the European Union as proof of compliance with the Renewable Energy Directive (2009/28/EC). This means that any RSB certified operator producing liquid biofuels can access the EU Market without further verifications.
