IUCN provides policy guidance (position papers and information papers) for major environmental conventions and conferences.

Our statutes, the rules governing IUCN, along with resolutions and recommendations voted by IUCN member organizations over the past six decades, are all available on-line.

Our databases, research tools and management guides – particularly on species, biodiversity, ecosystems and protected areas – are global standards in their fields. The IUCN Red List of Threatened Species™ for example has regularly and comprehensively assessed the extinction risk of animal and plant species for over 40 years.
