Countdown 2025

Countdown is a global initiative that promotes and accelerates solutions to the climate crisis, turning ideas into tangible action. The 2025 edition of TEDxBrussels Countdown brings together local and international players to share their ideas on energy, water management, biodiversity and climate justice.

The event takes place on November 18, 2025, in the evocative setting of the Dinosaur Gallery at the Institute of Natural Sciences. A symbolic place that reminds us of the consequences of drastic changes on the planet and invites us to write a different story for our future.

Participants and speakers - young people, scientists, activists, economic players and committed citizens - meet to discuss the energy transition, adaptation to water challenges, protection of urban biodiversity and equity in the face of climate change. Together, they explore how to reinitialize our urban, economic and social systems to meet the 2030 climate targets, a crucial step towards carbon neutrality in 2050.

This is not just a theoretical discussion, but a call to action. Countdown invites each participant to consider how, individually and collectively, we can contribute to a livable future for Brussels and beyond.

Through these exchanges, we are building a new climate narrative, where each idea becomes a brick in the building of a regenerative economy adapted to today's challenges. This event is aimed at all those who are determined to understand and act in the face of the climate crisis, and who want to play an active part in the transformation needed for a sustainable future.
