November 18, 2025
18:00 - 22:30
Dinosaur Gallery
Institute of Natural Sciences

Countdown is a global initiative that transforms ideas into tangible actions in the face of the climate crisis. The 2025 edition of TEDxBrussels Countdown brings together local and international stakeholders in the symbolic setting of the Dinosaur Gallery, a place that reminds us of the consequences of drastic changes and invites us to write a different story for our future.

Young people, scientists, activists, economic players, and engaged citizens meet to discuss the energy transition, water management, urban biodiversity, and climate justice. Together, they explore how to reset our systems to achieve the 2030 climate goals, a crucial step towards carbon neutrality by 2050.

More than a discussion, it's a call to collective action. Countdown invites each participant to actively contribute to a future where life is good, for Brussels and beyond.

This event is held in 2 languages: French and English. A simultaneous AI transcription is offered.
