At CertiQ we issue certificates for energy generated from four sustainable sources sun, wind, water and biomass: Guarantees of Origin. CertiQ has been designated to do this by the Dutch government. CertiQ also issues certificates for energy generated from fossil sources: Disclosure certificates. The two types of certificates we issue, in electronic form, are the only valid proof in the Netherlands that energy has been generated either sustainably or from fossil sources. Certificates issued by CertiQ can be traded within Europe. For subsidy decisions, CertiQ provides the necessary information to the 'Rijksdienst voor Ondernemend Nederland' (RVO).
