Countdown 2025

To a better, greener, healthier, thriving, resilient, fairer, cooler, creative future.

Welcome to TEDxJohannesburg Countdown 2025, our yearly event where we come together to accelerate climate action. On Thursday, 25 September 2025, in Johannesburg, we take stock of our collective progress and identify gaps requiring our renewed commitment to building a greener, more just world.

Following the TED Countdown Summit in Nairobi, Kenya (June 2025), and building momentum towards the G20 climate meetings here in South Africa (October 2025) and COP30 in Brazil (November 2025), this highly anticipated event will focus on advancing climate policy targets and ensuring their effective implementation by 2030.

Come and explore with us the inspiring global South efforts to create a just energy transition, set ambitious emission reduction targets, and build a resilient future. In true TEDx style, engage with diverse perspectives—from scientists, policymakers and activists, to local community leaders and youth advocates—and learn how we can create effective, holistic and inclusive climate solutions. Be the first to hear about the groundbreaking technologies and transformative policies that will drive us towards a sustainable world, and witness how international collaborations and partnerships are energising both local and global climate action.

Join the movement. TEDxJohannesburg Countdown 2025 is a gathering of voices from every corner of society, across cultures, beliefs, and disciplines, dedicated to creating a sustainable future. Together, through the sharing of ideas, we can drive change, inspire action, and build a greener world.

Join us on 25 September 2025, as we countdown to a better future.
