Ideas change everything.
Creating an impact around us and on society is what TEDxBrussels is all about. Through local events, we share ideas to encourage action, bring together a diverse community, and foster the exchanges that enrich our daily lives.


Countdown 2025
Countdown is a global initiative that transforms ideas into tangible action in the face of the climate crisis. The 2025 edition of TEDxBrussels Countdown brings together local and international players 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 committed citizens meet to discuss the energy transition, water management, urban biodiversity and climate justice. Together, they explore how to reset our systems to meet the 2030 climate targets, a crucial step towards carbon neutrality in 2050.
More than a discussion, it's a call to collective action. Countdown invites every participant to actively contribute to a livable future for Brussels and beyond.
