TED speakers share a blueprint for a beautiful net-zero future. This plan – along with inspiring stories of local Colorado action – will be amplified by hundreds of TEDx Countdown events around the world and through a special global livestream event.

Mark your calendars for the Countdown global livestream. Building on the success of the 2020 Countdown launch, this virtual event will lay out a credible and realistic pathway to a net-zero future by bringing together key solutions from the Countdown Summit, stories of local action from around the world, cutting-edge science and technology, social and cultural discussions, powerful performances and a glocal (Global + Colorado local) call to action.

By presenting a real pathway to achieving net-zero, the Countdown global livestream is designed to bring people all over the world together to celebrate and spread the word ahead of the decisive United Nations Climate Conference COP26.
