is a collaboration powered by TED and Leaders’ Quest.

Since its launch in 2020, TED Countdown has mobilized the world’s boldest problem-solvers to address climate impacts being felt across communities everywhere — from rising energy costs to severe weather. The shift to a cleaner, healthier and more affordable future is already underway. Our mission is to accelerate that momentum by changing the narrative through compelling storytelling, identifying and scaling high-impact solutions, and building a collaborative community by bringing people together across sectors and regions.

TEDx Countdown supports locally-curated climate events, giving host communities the opportunity to showcase their own innovative solutions with the world. In 2025, TED selected TEDxHouston as one of the 19 TEDxCountdown events in 13 countries to participate in the TEDxCountdown anchor program, convening thought leaders from around the world to share diverse perspectives, build community and foster new collaborations that can lead to tangible progress.
