The Members' Assembly is the highest decision-making body of IUCN. It brings together IUCN Members to debate and establish environmental policy, to approve the IUCN Programme and to elect the IUCN Council and President.
The Members’ Assembly takes place every four years during the World Conservation Congress and is where IUCN’s Member organisations collectively decide on actions to address the world’s most pressing and often controversial conservation and sustainable development challenges.
IUCN’s membership currently stands at over 1,300 and includes some of the most influential government and civil society organisations from more than 160 countries, giving the decisions taken at the IUCN Congress a powerful mandate. Through motions (often brought forward by the IUCN Membership), Resolutions and Recommendations on important conservation issues are are adopted by this unique global environmental parliament of governments and NGOs, guiding IUCN’s policy and work programme and as well as influencing many other organisations around the world.
