S4 #1 | Where are we in the CDR story and where are we going?
Welcome back to The Carbon Removal Show! We’re kicking off Season 4 with a view from the top - checking in on the state of the carbon removal industry here in the dizzying heights of 2025.
In this episode:
🌍 Where are we now? Durable CDR purchases hit 8 million tonnes in 2024 (a 78% bump from 2023), but 64% of that was Microsoft flexing. Deliveries? Still catching up – and most of it’s biochar.
📉 Caveats, ahoy: Sales are booming, but actual removals are still lagging. The buyer pool is basically a tech giant party.
🚨 Bubble watch: Are we living in a beautifully optimistic carbon bubble? Is it about to pop? Will Tom’s optimism hat survive the bubble bath? We explore industry hype vs. hard truths, including the risks of undelivered credits and startup casualties.
📊 The vibe check: Emily’s on an emotional rollercoaster. Tom is backing the CDR horse. Ben’s beard is greyer. Collectively, we’re cautiously hopeful.
🛠️ What needs to happen?: Scaling isn’t just tech - it’s finance, policy, public understanding, and clear comms. We need to get the message out of the bubble and into the next layer of the onion. (Just… not into Emily’s bubble bath. Please.)
🚗 A history lesson you didn’t know you needed: Did you know the best-selling car in 1897 was electric? We could’ve been 100 years ahead… but markets are messy.

Introducing... Grounded: A Climate Startup Journey
While you’re waiting for more episodes of The Carbon Removal Show, we wanted to introduce you to another project that our very own Tom Previte has been busy on…
Grounded: A Climate Startup Journey
This is the story of a startup that wants to remove carbon from the atmosphere and help reshape our relationship with the planet. Ideally without burning to the ground in the process.
It was a good few years back when Tom stumbled across biochar. That was during the first season of The Carbon Removal Show. And it turns out that this biochar stuff… it's not just an ancient technology but also a cutting-edge solution for today’s climate problems.
Grounded: A Climate Startup Journey captures the highs and lows of a green startup - from sharp learning curves to unlikely breakthroughs. Listen in as Tom digs deep into the realities and complexities of setting up a carbon removal project, and gets to grips with the science, the money, and everything it takes to build an environmentally (and financially) sustainable business.
Because if we’re going to save the planet, we’re going to need a lot more businesses like this one.

S3 #5 | How can companies contribute to industry scale?: Gigaton thinking - with MASH Makes
What happens when an individual company bakes industry scale up into their business philosophy? In this episode, Jakob Andersen shares the “gigaton thinking” mindset that drives his company, MASH Makes, in their approach to business and biochar.
MASH Makes started as a project at the Technological University of Denmark focusing on technology that could convert various waste streams (mainly residue biomass) into different energy products. In short, MASH Makes use automated machines that are able to produce bio oil, hydrogen and electricity from agricultural waste, with the main byproduct of this process being biochar – a soil amendment that actively absorbs CO2 from the atmosphere.
Big thanks to MASH Makes for supporting this episode.
