Only taking into account greenhouse gas emissions can lead to inadequate product reviews and recommendations for action, in particular when other environmental impacts have not been considered at all. Therefore, one task of further studies is to take other impact categories into consideration. Since natural fibres are used in many industry sectors, certification is a suitable instrument to prove sustainability. At the moment there are certification systems available which insure the production of biomass in a social and environmentally sustainable way. For natural technical fibres there are two favourable systems in place which are recognized worldwide. These are (in alphabetical order): 1. International Sustainability & Carbon Certification (ISCC PLUS) for food and feed products as well as for technical/chemical applications (e. g. bioplastics) and applications in the bioenergy sector (e. g. solid biomass). 2. Roundtable on Sustainable Biomaterials (RSB) is an international multi-stakeholder initiative for the global standard and certification scheme for sustainable production of biomaterials and biofuels. Natural fibres certified as sustainable have hitherto been unavailable on the market. However, the ISCC PLUS certification is currently underway for different hemp fibre producers within Europe. So it is expected that the first sustainable certificated natural fibres will be available by the end of 2015.
