The cultivation of renewable resources (usually from forestry, agriculture and sometimes from marine aquaculture) has a huge impact on the sustainability of the final bio-based products. Due to the EU and national renewable energy policies, certification schemes have been developed that adhere to the conditions laid down in the EU Renewable Energy Directive (i.e. ISCC or REDcert). Some offer also adapted schemes applicable to the material use, not only to energy.
For wood, sustainability certification schemes (see FSC and PEFC) were developed before the renewable energy policy due to concerns about unsustainable forestry practices in many parts of the world. There are also specific schemes for agricultural biomass in general (e.g. ISCC+) or specific type of biomass (e.g. RSPO for palm oil, Bonsurco for sugar or RTRS for soy).
Besides the certification on sustainable biomass resourcing, there are certification schemes to determine the bio-based content of a product, which is relevant to show how much bio-based material is actually used in a specific product (e.g. ok biobased).
Finally, certification schemes are in place to proof the end-of-life claims of bio-based products. There are schemes to certify that products can be composted under industrial conditions (e.g. The Seedling or DIN Certco), are ready to be composted at home (e.g. ok compost HOME) or even biodegrade in soil (OK biodegradable in SOIL or DIN Certco) or sea water (OK biodegradable in MARINE).
