The plan

Countdown seeks to answer five fundamental, interconnected questions that help inform a blueprint for a cleaner future.

We are bringing together scientists, activists, entrepreneurs, urban planners, farmers, CEOs, investors, artists, government officials, and others to find the most effective, evidence-based ideas out there. Our goal is to identify the bold solutions that can be activated when people break out of their silos and rise to the challenge.


How rapidly can we switch to 100% clean power?


How can we upgrade the way we move people and things?

Data App

How can we re-imagine and re-make the stuff around us?


How can we spark a worldwide shift to healthier food systems?

Earth Globe

How do we better protect and re-green the earth?

Countdown in 2020 and beyond

Global Launch

On October 10, 2020, we hosted a virtual event to hear from leading thinkers and doers about what a healthy, abundant, zero-emission future can look like; stirring examples of real progress underway; and powerful reasons why this post-crisis moment is the time to act. Hundreds of events took place simultaneously around the world. Check out all the talks and performances.

Accelerate progress
October 2020 – October 2021

Building on the ideas shared on 10.10.2020, we pushed forward fresh commitments and action on specific initiatives in the lead-up to the Countdown Summit and to the UN Climate Change Conference (COP26) in 2021.

Countdown Summit + local events + global livestream
October 2021

We shared a blueprint for a beautiful net-zero future at a central Summit of 1,000 leaders in Edinburgh, Scotland, further amplified by hundreds of TEDx Countdown events around the world and a global livestream. These events combined talks, case studies and workshops — and celebrated new commitments made, efforts in progress, and the people who are driving them. Watch the talks now.
