Climate Confident - Practical Climate Solutions That Cut Emissions
Climate Confident is a weekly podcast for business leaders, climate professionals, and policymakers who want to understand what is actually cutting emissions and how to scale those solutions. Host Tom Raftery speaks with executives, engineers, scientists, founders, and policymakers about turning climate ambition into measurable progress. Episodes examine technologies, business models, policies, and implementation strategies across energy, transport, industry, supply chains, food, and finance. Rather than distant targets or vague pledges, the show offers candid discussions about what is working, what is failing, where bottlenecks lie, and how leaders can make better decisions on decarbonisation, resilience, investment, and risk. It provides practical ideas and hard-earned lessons for turning climate commitments into action.

AI’s Power Boom Could Pull Factory-Built Nuclear Down the Cost Curve
Get in touch - leave me a messageAI data centres are creating an extraordinary new demand for electricity. The harder question is whether clean, firm power can be built quickly enough to meet it, without falling back on gas.My guest in this episode is Matt Loszak, co-founder and CEO of Aalo Atomics, which is developing small, factory-built nuclear reactors initially for AI data centres. The bet is
Enhanced Rock Weathering’s Scaling Bottleneck Is Proof, Not Rock
Get in touch - leave me a messageEnhanced rock weathering looks deceptively simple: crush suitable rock, spread it on farmland and let chemistry remove CO₂. The harder question is whether you can prove that removal reliably enough to make the economics work.I speak with Chris Zair, Director of Partnerships at UNDO, about what happens when enhanced rock weathering moves from controlled trials into
The 15-Litre Engine Opens Heavy-Duty Trucking to RNG—Economics Decide What Scales
Get in touch - leave me a messageFor years, renewable natural gas had a basic problem in heavy-duty trucking: it lacked a 15-litre engine capable of doing the work fleets expect from diesel. That barrier is disappearing. The harder question now is whether the economics and infrastructure stack up.My guest is Scott Brinner, Executive Vice President of RNG Solutions at NoPetro Energy, who works acro
Carbon Removal’s Real Bottleneck Isn’t Technology. It’s Demand.
Get in touch - leave me a messageCarbon removal is often framed as a technology problem. But what if the harder constraint is demand, and what if waiting decades to remove a tonne of CO₂ carries a climate cost of its own?My guest is Barclay Rogers, founder and CEO of Graphyte, a durable carbon removal company using agricultural and timber residues in a process it calls Carbon Casting. He brings a
Generation Is Not Delivery: The Grid Problem Behind Decarbonisation
Get in touch - leave me a messageBuilding more renewable generation is not enough if the grid cannot carry the electricity to where it is needed. Curtailment, connection queues and delayed infrastructure are turning grid capacity into a climate and competitiveness constraint.My guest today is Niklas Persson, CEO of Grid Integration at Hitachi Energy, with nearly three decades in electrification. W
Solar, Batteries and EVs Are Turning Delay Into an Investment Risk
Get in touch - leave me a messageSolar, batteries and EVs are moving fast enough to change the risk calculus for energy investment.

We examine what accelera
Long-Duration Energy Storage Is Ready. The Energy Markets Aren’t
Get in touch - leave me a messageLong-duration energy storage is increasingly ready to deploy. The harder problem is that electricity markets still struggle to value what duration actually provides - flexibility, reliability and power when the sun sets, the wind drops and demand peaks.My guest is Julia Souder, CEO of the Long Duration Energy Storage Council. She works across the policy, finance an
Buyer Pressure Helped Avoid 2 Million Hectares of Deforestation
Get in touch - leave me a messageTwo million hectares of avoided deforestation is not a theoretical climate benefit.
