NEW: Speaker lineup for Countdown Global Launch now available. See the full program.
Global Launch

To make progress on climate action we need to collaborate on a global scale, and your community has an important role to play.

On 10.10.2020, Countdown will launch globally with a virtual event, and we invite you to join us. Watch online at home with your family and friends, or sign up to host a TEDx Countdown event of your own with your community, in your language, for your time zone.

Tune in on 10.10.2020 on TED's channel on YouTube. In the meantime, sign up to get updates and reminders.


Live: 11am-5pm Eastern Standard Time / 5-11pm Central European Time

More than 50 speakers feature in five curated sessions that combine TED's signature blend of actionable and research-backed ideas, cutting-edge science, and moments of wonder and inspiration.


You can join an event near you or on the other side of the world. Search to find one that works for you:

Anyone, anywhere can sign up to host their own TEDx Countdown event, of any size on 10.10.2020 or afterwards. These events can take any shape – you might host a watch party featuring talks from the event, curate original local talks, facilitate breakout conversations following the virtual sessions or invite a local leader or artist to welcome guests or share a performance.


Once your application is accepted, you will be given a TEDx license under which to host your event. While most events this October will need to be virtual, we expect that some communities may be ready to meet in person. We advise everyone to pay attention to local guidelines about gatherings. See our working list of frequently asked questions to learn more.

Event Resources

To help make your event successful, the Countdown team will provide the following resources after you sign up:

  • Training: virtual sessions about how to organize a great virtual or in-person TEDx Countdown event; these will be led by our team and experienced TEDx organizers (check out the first information session)

  • Toolkits: a host guide with discussion topics and program details, as well as a design identity kit with graphics to use for your event’s digital and physical spaces

Special Guidelines for Businesses

Businesses can also register to host TEDx Countdown events for their organizations – including live speakers and/or watch parties – free of charge. These events are for an internal audience only, and the TEDx business license fees are waived.

Following the 10.10.2020 Global Launch, there will additional opportunities to keep your community engaged in Countdown. You can host and facilitate small-group climate conversations with your community through regular Countdown Circles and / or plan to host your own event alongside the Countdown Summit in 2021.
