Let’s face it. The United States, and, really, the entire world, has squandered much of the time that has elapsed since climate change first became a concern more than forty years ago.

Increasingly, scientists are warning that taking coal plants offline, building wind and solar farms here and there, and planting trees, even everywhere, aren’t going to keep our planet from heating to the point of human misery. Twenty years from now, we’re going to wish we had started thinking about not just carbon-zero technologies, but carbon-negative ones.

Last year we spoke with the founder of Air Company, which makes carbon-negative vodka by starting with liquid CO2 and turning it into ethanol, and then further refining it into a product sold in high-end liquor stores. Was it possible to skip the final refining steps and just use the ethanol as fuel? Yes, we were told, but that would be a waste of what was already close to being a premium product.

Which leads to the question, are there any efforts underway to take carbon out of the atmosphere on an industrial scale? And if so, what would be the entire product chain?

One company already doing that is Global Thermostat, and its CEO is our guest today.
