The campaign  

IDB is celebrated on 22 May annually to commemorate the adoption of the text of the Convention on Biological Diversity (CBD) and to provide an opportunity to foster wide support for the implementation of the Convention, its Protocols and related action frameworks.  

The IDB 2026 campaign will help connect local initiatives with the 23 global targets of the Kunming-Montreal Global Biodiversity Framework (KMGBF), focusing the world’s attention on the importance of applying the whole-of-society approach adopted within the Framework. 

Applying the whole-of-society approach includes ways to enlist, enable, empower and leverage contributions of actors other than national governments at the local level, including indigenous peoples and local communities, sub-national governments, cities and other local authorities, women and youth groups, businesses and financial institutions, and other civil society organizations, among others.   

 
Success in halting and reversing biodiversity loss hinges on the world’s ability to leverage the vital tapestry of local action in support of government-led actions. It is a two-way street: 

• Governments are expected to create enabling environments that are conducive to inclusive and meaningful participation of all actors in planning and implementation, including by ensuring access to information pertaining to the National Biodiversity Strategies and Action Plans (NBSAPs)—the master documents translating the global ambition of the KMGBF into measurable national undertakings. 

• Actors other than national governments are expected to seize all opportunities to contribute to planning and implementation, including by taking part in existing government-led processes and consultations, and by taking initiatives and actions aligned with the KMGBF, with the NBSAP and national targets serving as a guide.
