Carbon Clarity#19: Building more than networks: How energy infrastructure creates social value AND saves carbon.When you hear about half-billion-pound heat network projects, you probably think: carbon savings, right? But what if I told you these massive energy infrastructure schemes are also creating apprenticeships, building local supply chains, and bringing serious inward investment to cities? Kit Gillibrand from Hermetica Black has spent over a decade turning complex energy projects into reality – from Madagascar to Manchester. And he's got a powerful message: the best energy infrastructure projects don't just decarbonize cities, they transform them. In this conversation, Kit explains how places like Greater Manchester are using long-term energ...

Carbon Clarity#16 How data centers could heat your morning shower . With Andrew CrippsIn one possible transition to low carbon heat we might spend millions on individual heat pumps for every home and building... but what if there's a smarter way to heat entire areas of our towns and cities?In this episode, I'm talking to Andrew Cripps from Vital Energy about heat networks - the technology that's been quietly heating more of our cities than you might realise for decades, and could be the key to decarbonising homes and other buildings.In this fascinating conversation, we explore how one energy centre can heat 10s, 100s, or even 1000...

Carbon Clarity#15. Don't look back: Construction's missing feedback loop with Joe-Jack Williams.We spend weeks perfecting tender documents for projects we might not even win, but how much time do we spend learning from the buildings we actually build? Spoiler alert: almost none. In this wide-ranging conversation, I discuss with Joe-Jack Williams from Bywater how the construction industry has developed a serious case of selective blindness when it comes to post-occupancy evaluation – and why it's such a missed opportunity.But that's just one of the things we talk about!Alongside some great insights to the use of timber in construction, Bywater's speciality, Joe-Jack tak...

Carbon Clarity#14 Lock it in. Why carbon storage matters.We all know we need to cut carbon emissions... but what about the carbon that's already out there?I recently sat down with Garrett Boudinot, founder of Vy-Carb, and he shared a really powerful perspective. He says it's not just about fixing the leaky tap – it's also about mopping up all the water that's already spilled!Mitigation, reducing our emissions, is absolutely non-negotiable, but if we're serious about hitting our climate targets, we have to think about actively removing and storing carbon too.Garrett explains both carbon capture and storage, what options are av...

Carbon Clarity#13 The Critical Chain: Minerals, Geopolitics, and the Green TransitionWhat do electric vehicles, wind turbines, smartphones, and satellites all have in common?They rely on a complex, often invisible web of elements – rare earths and critical minerals – pulled from the ground, refined across borders, and essential to our transition to a net-zero carbon future.But here’s the catch – the term “critical” isn’t as clear-cut as it sounds. It depends on who you ask, where you’re standing, and what you need.In this episode, we dig deep into the world of critical minerals:What makes a mineral critic...
