Climate Takes is Carbon13's podcast where we ask climate entrepreneurs, innovators and funders for their takes on their industry and climate challenges, while also asking what it takes to solve the climate emergency.
Carbon13 is the Venture Builder for the climate emergency. Based in Cambridge, London and Berlin, we support and invest in entrepreneurs tackling challenges to Earth's Vital Systems.
Since 2021, we have worked with over 1000 entrepreneurs, invested in over 70 startups which collectively have a decarbonisation potential of 500 million tonnes per year by 2040.
Climate Takes is our chance to invite special guests from this community, and share the learnings, insights and determination needed to scale climate solutions.
Sara Jones interviews Georg Reifferscheid about how REWE Group's Climate Tech Ventures drives innovation and tackles climate challenges within Europe's retail sector.

Climate Takes Deeptech VC
Welcome to Carbon13's podcast "Climate Takes" where we ask special guests for their "takes" on their industry and climate challenge, as well as setting a call to action, asking what will it take to solve the climate emergency?
In this episode, we're getting the investor's view of deeptech, how they evaluate deeptech startups, conduct due diligence, and view the endgame for exits.
Deeptech broadly refers to cutting edge solutions in engineering or science. Almost all the megatrends in 2025 involve deeptech: AI, robotics, industrialisation, energy security, dual use and biotech - and that applies to climate too.
In Carbon13's own portfolio, deeptech includes MatNex, building the world's largest supercomputer for materials science, or Nium, using nanotechnology to replace the Haber-Bosch process.
And that's a big change from the SaaS and app years - so it's vital that the investors working on early stage deeptech actually have the knowledge to make the right bets - and that's why we're talking to Dr Charlotte Kirk: PhD chemist turned industrialist innovator turned climate VC, with ultra endurance sports and armed forces experience to boot. She takes us through her journey, and what she prizes in deeptech startups - and it's far more than just the technology.

Climate Takes Corporate VCs
Welcome to Carbon13's podcast "Climate Takes" where we ask special guests for their "takes" on their industry and climate challenge, as well as setting a call to action, asking what will it take to solve the climate emergency?
In this episode we're looking at Corporate VCs and the role they play in funding climatetech startups. It's estimated that in 2024, CVCs invested over $10 billion into climatetech startups - but it's not just their chequebooks that are important to founders. CVCs can become an entrypoint into the parent company and in a sector where the majority of startups are b2b, and pilots, LOIs and Offtakes are the holy grails, this makes them an investor class well worth understanding.
To demystify CVCs, we're delighted to be joined by Mike Smeed, Managing Director of InMotion Ventures, Jaguar Land Rover's CVC. Their portfolio includes battery recycling, rare earths recycling and supply chain visibility solutions. Mike himself is passionate about connecting mission driven entrepreneurs to JLR's strategic goals, and elevating the work of CVCs across Europe.

Climate Takes Synthetic Biology
Welcome to Carbon13's podcast "Climate Takes" where we ask special guests for their "takes" on their industry and climate challenge, as well as setting a call to action, asking what will it take to solve the climate emergency?
In this episode we're looking at synthetic biology, which sounds simple: it means engineering organisms to have new functions. But it's not a peripheral technology, it is predicted to be one of the 21st century's most disruptive technologies on a scale similar to AI. The current bioeconomy is already $4 trillion, and it's projected to hit $30 trillion by 2050.
But like AI, synbio has a lot of challenges, and there's a graveyard of startups in this sector. In this episode, Tim Corcoran and Manuel Rios of Deep Blue Biotech give us their takes on why startups have struggled, and yet, why synbio could be so significant for human progress.

Climate Takes Critical Materials
Welcome to Carbon13's podcast "Climate Takes" where we ask special guests for their "takes" on their industry and climate challenge, as well as setting a call to action, asking what will it take to solve the climate emergency?
Climate Takes Critical Materials covers the most global question of this podcast so far: the supply chains of critical materials. They are the stuff we need for the world's energy transition, its energy storage, and even the screen you're reading this on.
But, one battery maker alone can have over 10,000 suppliers. A renewable energy project can be killed entirely by a 6 month delay in materials supply.
So we talk to Sarah Montgomery, CEO of Infyos, an AI supply chain operating system for energy and mobility, built by experts in Chinese supply chain data supply chain disruption.

Climate Takes Venture Builders
Welcome to Carbon13's podcast "Climate Takes" where we ask founders, investors and builders for their "takes" on their industry and climate challenge, as well as setting a call to action, asking what will it take to solve the climate emergency?
On Climate Takes Venture Builders, we're joined by two serial entrepreneurs who work within Carbon13: Puja Balachander and Nishul Saperia. Using their Founding and Venture Building experience, we take a look at the very model of Carbon13 itself.
Our conversation includes: What are venture builders, how do they differ to accelerators and venture studios, how do they work, and how do they make meaningful change in climate innovation?
Carbon13's own Venture Builder has seen over 1000 founders pass through our programmes, resulting in nearly 80 invested ventures, collectively worth over £230million, with a potential to reduce emissions by 500 million tonnes per year.

Climate Takes Ammonia
Welcome to Carbon13's podcast "Climate Takes" where we ask special guests for their "takes" on their industry and climate challenge, as well as setting a call to action, asking what will it take to solve the climate emergency?
On Climate Takes Ammonia, we're talking about the chemical that feeds half the world, is a $230 billion industry, and is key to a clean hydrogen future.
But which right now is the most polluting chemical process on earth.
To make one tonne of ammonia, two tonnes of emissions are generated.
But industry is so keen for Nium's clean ammonia, that they already have a $120 million project pipeline and $50 million in signed offtake agreements, while still at TRL 5.
We'll be getting the story behind those numbers and more, with CEO Lewis Jenkins.
We hope you enjoy the podcast and it becomes a catalyst for you for climate tech innovation too.

Climate Takes Concrete
Welcome to Carbon13's podcast "Climate Takes" where we ask special guests for their "takes" on their industry and climate challenge, as well as setting a call to action, asking what will it take to solve the climate emergency?
In this episode hosted by Sara Jones, we speak to Eliot Brooks, CEO and Co-founder of Cocoon Carbon. In just 18 months, the cofounding team has scaled their technology to TRL6, raised $5.4m in pre-seed funding, and grown the company to 12 people.
Eliot was already an award winning entrepreneur and Forbes 30 Under 30 when he joined Carbon13's Venture Builder in 2023, in this episode, he shares his journey and his mission to make Cocoon Carbon one of the fastest growing climate hardware companies in the world.
Why does concrete matter? Concrete is the second most used man-made material after water. It's also one of the biggest single emitters of carbon dioxide, responsible for 8% of emissions. If it was a country, it would be the 3rd or 4th most polluting country in the world.
Sara Jones is Head of Marketing at Carbon13. She's worked in London's startup ecosystem for well over a decade and has been with Carbon13 since 2020, turning it into one of the strongest magnets for climate focused entrepreneurs in Europe.
