International Day for Biological Diversity (IDB) 2026
The International Day for Biological Diversity (IDB) is celebrated on 22 May annually to commemorate the adoption of the text of the Convention on Biological Diversity 
(CBD) on 22 May 1992. This observance proclaimed by the United Nations General Assembly provides an opportunity to foster wide support for the implementation of the Convention, its Protocols and related action frameworks.
“Acting locally for global impact” is the theme of the 2026 edition of IDB. Here is the IDB 2026 theme in the five other official languages of the United Nations:
-
اليوم الدولي للتنوع البيولوجي 2026: العمل على الصعيد المحلي لإحداث تأثير عالمي
-
2026年国际生物多样性日：立足本地，影响全球
-
Journée internationale de la diversité biologique 2026 : agir au niveau local dans la perspective de retombées mondiales
-
Международный день биоразнообразия 2026 г.: действия на местном уровне для глобального воздействия
-
Día Internacional de la Diversidad Biológica 2026: Acción local para un impacto mundial
At the crux of the IDB 2026 theme lies the fact that 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 other than national governments 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.
Five months ahead of the start of the 2026 United Nations Biodiversity Conference in Armenia, the celebration of IDB 2026 around the world constitutes a universal moment to demonstrate that the implementation of the Kunming-Montreal Global Biodiversity Framework (KMGBF) is underway.
