In this episode of Climate Confident, I speak with Alice Chun, inventor of the world’s first inflatable, origami-inspired solar light and founder of Solight Design. Alice shares how a career in material technology and a deeply personal experience with her son’s asthma led her to tackle energy poverty, disaster relief, and carbon emissions with a single, deceptively simple product: the SolarPuff™.

We discuss the staggering health and environmental toll of kerosene lighting, especially in off-grid and disaster-affected communities — and how collapsible, durable solar lanterns are not only cleaner and safer, but can also act as tools for education, safety, and psychological recovery.

Alice walks us through the practical design choices (like sailcloth and origami folds) that make the lights lightweight, shippable, and long-lasting. She also unpacks her field experiences from Haiti to Ukraine, why she insists on personally delivering lights, and the complex balance of running a mission-driven company that also needs to survive commercially.

Key takeaways:

• Why light access is essential for disaster resilience and safety
• How solar design can scale through beauty, durability, and function
• The unexpected link between solar tech and trauma recovery in children
• What business models can sustain social impact in climate tech

In this episode of the Climate Confident podcast, I spoke with Ryan Schermerhorn, a US-based patent attorney who’s been helping clean tech innovators navigate the IP maze - until recently with the help of a now-suspended fast-track programme.

We discussed the United States Patent and Trademark Office’s (USPTO) Climate Change Mitigation Pilot Program, which allowed inventors of emissions-reducing technologies to get patents approved in months rather than years, at no cost. Ryan explained how it worked, why it was a big deal for clean tech startups, and how it quietly disappeared earlier this year following a political shift.

We also unpacked what this means for innovators now. Ryan shared practical alternatives - like using international patent offices with similar climate fast-track schemes and leveraging the Patent Prosecution Highway (PPH) to speed things up globally.

We also covered the balance between IP protection and open innovation, why patents still matter in the climate crisis, and how to protect ideas early without blowing the budget.

If you're working in climate tech, clean energy, or emissions monitoring and need to protect or scale your innovation, this episode is for you.

In this episode of the Climate Confident podcast, I sat down with John Sturman, Managing Director at NatPower UK, to dig deep into the realities of grid decarbonisation and energy transition at nation scale.

John pulled back the curtain on how NatPower is scaling up battery storage and renewable projects not just in the UK, but across the globe. From developing Europe’s largest battery storage pipeline to pioneering power solutions for maritime decarbonisation, this conversation gets into the detail of what's needed to hit net zero — and what’s holding us back.

We discussed:

• Why the UK is currently one of the strongest global markets for battery storage
• The urgent grid reform needed to meet the UK’s 2030 clean power targets
• How long-duration battery storage could replace gas peaker plants sooner than expected
• The overlooked challenge (and opportunity) of decarbonising the shipping industry
• Why AI will be essential to balancing increasingly complex power grids
• And why empowering communities is critical to speeding up the clean energy build-out

John didn’t shy away from naming the bottlenecks — planning delays, outdated infrastructure, and regulatory barriers — but he also laid out practical fixes that could unlock faster deployment of clean power.

If you’re serious about understanding the mechanics behind the transition to a net zero grid, this is one you don’t want to miss.

In this episode of the Climate Confident podcast, I sat down with Faustine Delasalle, CEO of the Mission Possible Partnership (MPP), to delve into the real challenges, and opportunities, of decarbonising heavy industry and transport.

Faustine and I explored the current state of industrial decarbonisation, including the progress made over the last five to six years in proving that sectors like steel, cement, and shipping can transition to low-carbon alternatives. But as she points out, technical feasibility doesn’t always translate into financial viability. The sticking point? Making green industrial projects bankable.

We discussed the role of the so-called "green premium" (or dirty discount), why demand signals are crucial, and how the current lack of buyers at scale is stalling momentum. Faustine makes a strong case for the combination of policy mandates and targeted subsidies to unlock investment - drawing comparisons with the growth trajectories of solar and electric vehicles.

A key takeaway from our chat: the path to scaling green hydrogen could start with ammonia, which Faustine sees as the first domino in the next industrial revolution. We also looked at which regions are moving fastest, what’s holding others back, and why emerging economies might play a central role in the coming decade.

If you're in policymaking, finance, or industry, and serious about accelerating climate action, this is one to tune into.

In this episode of the Climate Confident podcast, I had the pleasure of speaking with Sandhya Sabapathy, Global Head of Environment and Net Zero at Entain, about the evolving role of sustainability in business – and what it truly takes to make climate action effective, strategic, and inclusive.

We discussed how sustainability has moved from the sidelines to the boardroom, driven not only by regulation but by clear commercial logic. Sandhya pointed to examples like IKEA – reducing emissions by 24% while growing revenue by 30% – as proof that climate strategy and profitability can go hand in hand.

We explored the growing influence of mandatory ESG reporting, the shift of climate accountability to audit committees, and how these trends are forcing businesses to be more transparent, not just more ambitious.

Sandhya also reflected on how to avoid burnout in purpose-driven work, why inclusivity leads to more resilient climate solutions, and the critical need to include marginalised voices in the climate conversation.

Listen in to hear why manufacturing might be further ahead on sustainability than you’d think, what we can learn from companies like Philip Morris (yes, really), and how even small actions can build corporate momentum for meaningful change.

Whether you’re leading a sustainability team, looking to influence from within, or just starting your climate journey – there’s something here for you.

In this episode of Climate Confident, I sit down with Chris Doherty, CEO of Joulen, to discuss how data, AI, and battery storage are changing the way homes and businesses interact with renewable energy. With energy costs fluctuating and grid constraints becoming more of a challenge, the role of smart energy management has never been more important.

Chris explains how virtual power plants (VPPs) allow households and small businesses to collectively act as a large-scale power provider, reducing costs and generating income. We explore how AI-driven algorithms optimise energy use, ensuring that people buy low and sell high—maximising savings and revenue.

We also break down the regulatory barriers that prevent wider adoption of decentralised energy and discuss what governments can do to speed up the transition. From Germany’s success in residential battery storage to the UK’s evolving energy market, we look at how different countries are tackling these challenges.

Other key topics:

• Why EVs with vehicle-to-grid (V2G) technology could replace home batteries
• How energy storage can help stabilise the grid and reduce investment in new infrastructure
• The financial incentives needed to scale solar and battery adoption in homes and businesses
• The growing role of demand-side management in balancing electricity supply

If you’re wondering how to make the most of your renewable energy system—or how policy can unlock wider adoption—this episode has you covered.

In this episode of Climate Confident, I sit down with Jenny Morgan, author of Cancel Culture in Climate, to explore how public shaming and polarisation are holding back real progress on climate solutions.

We already have the tools and technologies needed to reduce emissions, yet fear of criticism—whether from activists, media, or the public—often paralyses businesses and leaders. Jenny explains how cancel culture leads to three major pitfalls:

• Greenwashing – Overstating sustainability efforts to avoid backlash.
• Greenhushing – Staying silent about genuine climate initiatives to escape scrutiny.
• Green recanting – Companies reversing climate commitments due to heightened pressure.

Rather than tearing down imperfect efforts, Jenny advocates for empathetic accountability—holding organisations to account while keeping the door open for progress. We discuss how companies like Patagonia and Allbirds have embraced transparency over perfection, and how social media can be both a force for good and a major obstacle to climate communication.

Key takeaways:
✔ Why fear of being “called out” prevents meaningful climate action.
✔ How businesses can regain trust after sustainability missteps.
✔ Practical strategies to foster productive climate conversations.

Tune in to rethink how we approach climate accountability—and why working with people is more effective than working against them.

In this episode of Climate Confident, I sit down with Puja Balachander, CEO and co-founder of UpGreen, to explore how commercial landlords and asset managers can accelerate energy efficiency retrofits while keeping costs down.

Buildings account for nearly 40% of global carbon emissions, yet many remain inefficient due to financial and logistical barriers. UpGreen tackles this by reducing upfront retrofit costs and enabling landlords to recapture savings from tenants, turning sustainability upgrades into a viable business strategy.

We discuss:

• Why 87% of UK commercial buildings must undergo energy upgrades within the next five years to meet regulations.
• How UpGreen's model cuts retrofit costs by up to 80% while recovering 60% of expenses through tenant savings.
• The hidden inefficiencies preventing widespread adoption of energy retrofits, despite their cost-effectiveness.
• The challenges of scaling retrofits across different markets, from the UK’s public energy performance data to Germany’s fragmented regulations.
• The future of retrofits beyond energy efficiency, including climate adaptation measures for flood and heat resilience.

This episode offers practical insights for commercial landlords, sustainability professionals, and policymakers looking to unlock the full potential of building decarbonisation.

In this episode of Climate Confident, I sit down with Annalisa Bracco, a physical oceanographer and climate scientist at the Georgia Institute of Technology, to explore how our oceans are changing—and why it matters.

The ocean is a critical carbon sink, absorbing vast amounts of CO₂, but it’s also warming at an alarming rate, driving more extreme weather events and disrupting marine ecosystems. Annalisa explains how rising sea temperatures are fuelling stronger hurricanes, shifting rainfall patterns, and devastating biodiversity—particularly in coral reefs, where we’ve already lost up to 75% in the Atlantic alone.

We also discuss the role of marine protected areas, the surprising impact of sea cucumbers on coral survival, and how AI and machine learning are helping scientists map oceanic ecosystems. Annalisa shares insights on potential solutions, including ocean-based carbon sequestration, enhanced weathering, and the challenge of safely storing CO₂ at depth.

Key takeaways from this episode:
✅ Warming oceans are intensifying weather patterns and reducing freshwater availability.
✅ Coral bleaching threatens food security for over a billion people.
✅ AI is revolutionising how we track biodiversity and predict climate impacts.
✅ Marine conservation efforts can rapidly restore ecosystems and improve fisheries.

The health of our oceans is deeply intertwined with the future of our planet. Listen now to understand what’s at stake—and what we can do about it.
