carbon removal

Cutting emissions alone will not be enough. To avoid the worst effects of global climate change, Heirloom CEO and co-founder Shashank Samala believes we’ll also need to pull a lot of carbon out of the atmosphere...

This week on How I Built This Lab, Shashank’s leap into climate entrepreneurship, launching the company that, in just four years, built North America’s first operational carbon capture facility. Plus, Heirloom’s novel approach to carbon removal—one tray of limestone at a time.

In part 1 of our carbon removal series, we talked to Nan Ransohoff — Head of Climate at Stripe — about what it might take to jumpstart the market of carbon removal solutions. But what happens when there is a true, thriving market of buyers and sellers? How will suppliers effectively reach the right buyers, and as more solutions become available, how will buyers effectively vet the options?

In part 2, we address these questions and more, together with Brennan Spellacy, co-founder & CEO of Patch – a growing marketplace for carbon credits. 

We also cover many evolving market dynamics, like the potential differences between two sets of tons delivered, the opportunity and challenge of effectively educating buyers, the integration of software like Patch's API, verification solutions and their current limitations, how even the voluntary market is being held accountable for their carbon claims, and the role that Patch is playing to help develop this nascent industry.

By the way, if you like this episode, be sure to look out for part 3 of our series where we get into the nitty gritty of 3 emerging carbon removal solutions — ranging from biomass pyrolysis to carbon mineralization.

What happens when there’s demand for a solution that doesn’t quite exist yet?

Today, we bring on Nan Ransohoff to talk about this exact problem as it relates to carbon removal, and how Frontier — the initiative out of Stripe that she is leading – is using a nearly $1B advanced market commitment fund to try to jumpstart this market.

If you don’t know what that means, don’t worry – we’ve got you covered.

Throughout the episode, we discuss the multivariate carbon equation and why emission reductions are not enough, the difference between offsets and permanent removal, who’s paying for tons today, what solutions already exist and how Frontier is vetting them, moving down the cost curve, where policy fits in, and ultimately what success might look like in this nascent industry.

This is part 1 of our 3-part series on carbon removal. Look out next week for part 2 and part 3, where we dive into a growing marketplace for carbon and showcase several carbon removal solutions.

According to the 2022 report from the Intergovernmental Panel on Climate Change (IPCC), the world needs to cut carbon emissions drastically to avoid the worst effects of global warming. But that’s not all. In addition to reducing emissions, we also need to remove 6 to 10 billion tons of carbon dioxide from the atmosphere each year by 2050. 

This week on How I Built This Lab, Guy talks with Jan Wurzbacher, co-founder and CEO of Climeworks. They discuss how Jan and his team built the world’s largest direct air capture facility, which filters carbon dioxide from the air and stores it permanently underground. Plus, Jan’s optimistic vision of how humans can achieve the goal of reversing climate change.

Brands are promising to plant a tree for each can of beer, tshirt, or pair of trainers you buy, offsetting their carbon emissions so they can put an attractive ‘carbon negative’ sticker on a product to show green they - and you - truly are. But how effective is a new forest at offsetting a company’s emissions, what does ‘carbon negative’ really mean, and how do they go about proving they’ve achieved it?

Trees are just one type of carbon offset. Another, albeit promising but expensive, option is Direct Air Capture. Could that be the future of long term carbon offsetting? Greg Foot finds out.

To fight climate change, we need to clean up the global electricity system by replacing fossil fuel power plants with clean generation -- right? Climate author Solomon Goldstein-Rose thinks we need to do much more than that. Replacement isn't enough, he explains in this compelling talk: we need to rapidly develop a new global system capable of producing 12 times the amount of clean electricity we generate today. He shares four reasons why we need that expansion -- first, to electrify everything in all parts of the world (not just the wealthy ones) -- as well as some intriguing ideas for how we can get there.
