Several key international agreements and initiatives are shaping the landscape of nanotechnology: - OECD's Sponsorship Programme for the Testing of Manufactured Nanomaterials: This program encourages countries to share data and methodologies for testing the safety of nanomaterials. - ISO/TC 229 on Nanotechnologies: This technical committee develops international standards for terminology, measurement, and risk assessment in nanotechnology. - SAICM (Strategic Approach to International Chemicals Management): While not exclusively focused on nanotechnology, SAICM addresses the safe management of chemicals, including nanomaterials.
