ISO technical committee TC 331 aims to produce standardization in the field of biodiversity, for organisations to enhance their contribution to sustainable development. The committee was established in June 2020, and IUCN was the first liaison-A partnership to join in 2021. 40 countries are members of the committee (through their respective national standards organisations), 22 more are observers, and invitations for other countries to join are still open. In this webinar, the ISO TC331 manager will present the different projects undertaken in the technical committee, the different steps followed by each project before becoming a standard and how IUCN experts can collaborate in the elaboration of the future ISO standards on biodiversity.
