Gov4Nano will design and establish a well-positioned and broadly supported Nano Risk Governance Council (NRGC). Organizing, connecting and engaging are key activities in Gov4Nano and its creation of a sustainable NRGC. Gov4Nano will develop an operational trans disciplinary Nano Risk Governance Model (NRGM) for nanotechnologies, building on an established governance framework developed by the International Risk Governance Council (IRGC). Engaging stakeholders (including regulators) to proactively address nano-specific safety and seek dialogue for joint activities. NRGC and its precursor project Gov4Nano will engage, in order to support these activities, with the broad variety of stakeholders across all relevant nano-disciplines (chemical, biocides, food and feed, pharma and medical devices and materials development) and draft a review on our knowledge progress over the last decade whilst initiating dialog. To boost the quality of the dialog it will create a platform for dialogues between stakeholders in a “trusted environment” inclusive of civil society. The NRGC core business is to coordinate, guide and harmonize in order to overcome the fragmentation of current knowledge, information and needs over various sectors and disciplines (workers, consumers/patients, environmental safety) and to prepare the transfer of this knowledge. To that end, the NRGC will be equipped with a self-sustainable NanoSafety Governance Portal (NSGP) consolidating state-of-the-art and progressive nanosafety governance tools including ones for dialogues and measuring risk perception. Major efforts will be towards requirements for data harmonization and data curation to be defined and laid down in guidance on obtaining harmonized and standardized quality-scored data collections promoting a big data approach for nano-toxicology. Research activities will be initiated for regulatory sound knowledge in support of harmonized (OECD) guidance for characterization and testing of nanomaterials.
