Combining new TED Talks with live performances, short films, expert conversations and more, this event is intended to vividly explain the climate crisis, focusing on solutions and calling for leaders and citizens everywhere to step up. Countdown is a global initiative to champion and accelerate solutions to the climate crisis. The goal is to build a better future by cutting greenhouse gas emissions in half by 2030 in the race to a zero-carbon world -- a world that is safer, cleaner and fairer for everyone. Every person, organization, company, city and nation is invited to collaborate with Countdown and take action on climate. It is a movement open to everyone -- and everyone has a vital role to play. Countdown is one part of a broader series of actions and events this fall, all with the collective objective of informing and activating millions in the lead-up to a successful UN Climate Change Conference in November 2021.
