Convening
Stronger Together
IUCN convenes leaders who set the agenda for global conservation. No other organization possesses such an extensive network spanning the conservation field, or uses them as effectively to catalyze tangible, durable impact.
Science

IUCN originates and activates some of the most influential conservation science in the field. Our Commissions include more than 17,000 scientists, analysts, researchers, experts, advocates, policymakers, and project leaders whose combined expertise constitutes the world’s largest conservation knowledge base.
Policy
Strategic Policymaking
IUCN has led the charge for transformative environmental policymaking since 1972, when we became the official advisor on nature under the World Heritage Convention. IUCN motions have resulted in more than 1,450 Resolutions and Recommendations, which serve as the basis for influencing conservation policy at the species, site, national, and global levels.
