We at Sustainable Resources Verification Scheme (SURE), live and breathe sustainability. Our mission is to ensure the sustainable and responsible use of biomass within the energy sector and to make a tangible contribution to greenhouse gas reduction. As a voluntary certification system, we have defined verifiable criteria for the production of electricity and heat from solid biomass and biogas in accordance with the principles of the European Energy Directive (RED II) and derived indicators which are regularly monitored by independent auditors.
