The Solar Analogy
Carbon removal technology is currently comparable to solar technology in the 1970s.
Government support and technological innovation are essential to accelerate its development.

Soil Carbon Moonshot
Soil is a large carbon sink, and certain agricultural practices enhance carbon sequestration.
These practices include cover cropping, no-till agriculture, and agroforestry.

Sustainable Farming Practices
Cover cropping involves planting crops between main crops to protect and cover soil.
Last year, somebody explained the problem of climate change to me with a metaphor that I’ve never been able to forget. They said: Imagine a bathtub. The bathtub is the planet’s atmosphere. The faucet is on full blast and it’s quickly filling with water. The gushing faucet represents every source of global carbon emissions, from "Big Agriculture" and energy companies to cars and cow farts. The water is carbon itself. The challenge of climate change mitigation is straightforward: Stop the water from filling the tub, spilling over the edge, and destroying the planet. There are a lot of environmentalists and federal policies that focus on one part of the picture. They want to turn the tap to reduce emissions. This is what wind, solar, and geothermal energy does. This is what electric cars do. It is an absolutely essential goal. But a very full tub can still overflow even with a slower-dripping faucet. So we need to think bigger to save the world. We need a plan that goes beyond the faucet. We need to drain water from the basin by pulling the plug at the bottom of the tub—that is, to suck a huge amount of carbon dioxide out of the atmosphere and flush them away. So, how do you pull the plug?
In the last few years, I’ve become very interested in a technology called carbon removal—and especially direct air capture. Imagine, basically, a giant factory that pulls carbon from the atmosphere and buries it. This technology is still incredibly expensive. In August 2022, it is not remotely close to being a global solution to climate change. But there is a chance it may be the most important technology of the 2020s and 2030s, if you understand the problem of the tub, the water, the faucet, and the plug.
Today’s guest is Giana Amador. She is the co-founder and policy director of Carbon180, an interdisciplinary organization devoted to carbon-removal technologies. In this episode, she explains how different carbon removal technology works; why there are a million carbon removal plants all over the planet already; the technology and cost problems of vacuuming the atmosphere; and why some people think this technology won’t ever work in the first place.
