The RSB Standard covers biomass, as well as fuels and material products from bio- based and recycled carbon, including fossil waste. This includes liquid biofuels, gaseous biofuels, recycled carbon fuels, non-bio-based renewable fuels, biomass for heat and energy, chemicals and polymers, textiles and fibres. RSB strives to support the development of sustainable bio-based and recycled products, addressing criteria such as food and water insecurity, climate change and biodiversity loss.

The Roundtable on Sustainable Biomaterials (RSB) is an international multi-stakeholder-initiative that brings together producers, environmental and other non-governmental organisations as well as companies to promote the sustainable production and processing of biomass products.

RSB has been recommended in the Blue Angel award criteria as the only certification system for biomass. Various NGOs, such as WWF and Solidaridad, have contributed to the development of the standard.
