It is possible to clean the atmosphere? (going beyond the efforts to neutralize new emissions)

All the last reports by the United Nations Framework Convention on Climate Change clearly state that only by removing CO2 from the atmosphere we can meet the Paris Agreement Goals.

In parallel with the ongoing process of reducing and mitigating new emissions under the Paris Agreement, is it possible to clean up the excess of CO2 in the atmosphere that already exists?

For that to be possible, a new legal framework is needed!

Climate must be recognised and managed for what it is de facto:

A Common Good that belongs to all generations!

The Common Heritage of Humankind

TED COUNTDOWN initiatives intent to championing and accelerating solutions to the climate crisis, support locally curated TEDx events and showcase climate solutions in the world through the TED stage.

TEDxPorto, will host the TEDxPorto CountDown – Online, with the goal of opening a worldwide discussion about the concept of global commons, climate, and the rights of future generations to benefit from this Heritage that has always belonged to everyone in the real world.

On June 6 and 7, 2023, join us on this discussion!
