In March 2014, the German Federal Ministry for the Environment (UBA) published an impact assessment arguing that a horizontal European registry of nanomaterials based on existing product regulations and focusing on substance registration would be most cost efficient. The report evaluates the impact of the establishment of a European Register of Products Containing Nanomaterials (ERPN) as suggested in a concept publication published in June 2012 by the UBA. The goal of the establishment of an ERPN is to ensure regulatory oversight over the use of nanomaterials and to better estimate human exposures and health effects arising from nanomaterials in consumer products. The Öko-Institut e.V. from Freiburg, Germany, which was commissioned to carry out the impact assessment, concluded in the report that a horizontal registry based on existing product regulations would save up to 95% of administrative costs for public authorities and notifiers.
