Hey, it's Akshad.

I'll be going to COP28 in Dubai later this month.

I'd love to find a way to answer the many questions you may have of the United Nations Climate Conference.

Check out the show notes for details on how to send us your questions.

Thanks for listening.

Welcome to Zero.

I'm Akshadrati.

This week, reduce, reuse, remove. The sad reality is that even though the world has clear climate goals, it was late in starting to do something about them.

That's why meeting these goals will not just mean an end to dumping greenhouse gas emissions,

but also undoing some of that damage by drawing down carbon dioxide from the air.

That's what we are going to talk about today.

This is the second in a series that looks at the state of carbon capture and carbon removal technologies.

Last week, I talked to Emily

Grubert. She's a professor at Notre Dame University and we talked about the potential and

limits of technologies that trap emissions before they exit a smokestack. That type of point source carbon

capture is expected to do the heavy lifting as the world gets close to net zero by 2050.

But as we get closer to that date, which is only 27 years from now, net zero models say that

carbon removal technologies will have to kick into gear. The International Energy Agency suggests

the world needs 1 billion tons of carbon dioxide removed from the

air by 2050.

Currently, we draw down less than 10,000 tons each year.

I think it's really indisputable right now that we will overrun our climate safety barriers,
