Unlocking preventive healthcare for people and planet.

Health is one of our most complex and deeply interconnected systems—shaping and shaped by climate change, food, agriculture, policy, and poverty. While healthcare delivery carries a significant environmental footprint, climate impacts from extreme heat to air pollution are rapidly worsening health outcomes worldwide. In this episode, Wayne and Sally explore how to shift from reactive "sickness" systems to preventive, climate-resilient healthcare.

Guests

Dr Sandro Demaio — Director, World Health Organization Asia Pacific Centre for Environment and Health

Dr Jonny Groome — Associate Medical Lead for Sustainability, Nuffield Health; Climate Director, Tottenham Creative Climate Collaborative; Consultant in Paediatric Anaesthesia, Royal London Hospital

What We Cover

• Why changing disease patterns and climate risks require an urgent transition in global health systems
• The double burden: How healthcare creates 5–7% of national carbon footprints while facing escalating climate impacts
• Decarbonizing scope 3 health supply chains and hospitals while keeping products and care affordable
• Lessons from Asia and the Pacific: Relocating vulnerable hospitals, greening cities, and driving regional political consensus
• Shifting from a reactive "sickness service" to preventive, plant-forward, community-centered wellcare
• The "7 Acts" for individual action and leveraging creative communities to build local climate resilience

Key Quotes

"The solutions that are required to tackle chronic disease are the same things that we need to do to address climate change and environmental degradation." — Dr Sandro Demaio

"Healthcare's emissions contribute 4 to 5%, but we touch about 90% of global supply chains... If we bring our entire supply chain along, we start to bleed into other carbon emission routes." — Dr Jonny Groome

The Line Dance (with a Flashmob twist) — A line dance because transforming healthcare requires everyone moving in synchronized choreography regardless of what you wear, and a flashmob for the rapid, emergency response needed when systemic crises strike.

How finance underpins all sector transitions—and how we fix the flow

The finance system underpins almost every major transition underway, acting both as a root cause of past systemic failures and as the ultimate lever for future solutions. In this episode, Wayne and Sally explore how to unlock financial flows to accelerate transitions across energy, food, nature, and health—despite political headwinds, market backlashes, and regulatory hurdles.

Guests

• Paul Dickinson — Co-Founder and Managing Partner, Transition Value Partners; Co-Host, Outrage + Optimism
• Claudine Blamey — Chief Sustainability Officer, Aviva

What We Cover

• Why finance acts as a "bird's-eye view" underpinning all other systems transitions
• Navigating political pushback, "Planet Trump vs. Planet Biden," and anti-ESG headwinds
• Reframing policy makers as "policy collaborators" rather than adversaries
• Shift in corporate action: Moving beyond net zero to climate adaptation, community resilience, and risk management
• How to turn nature into an investable asset class through ecosystem services and catchment-level multi-solving
• The role of individual consumers and investors in driving broader financial systems change

Key Quotes

"We need to reframe the policy maker as the policy collaborator... to unleash the investment which will give us clean and more wealthy societies." — Paul Dickinson

"Our vision is for nature to become an investable asset... creating the product and the customer so that nature yields a return." — Claudine Blamey

The Health System Transition

The food system is full of big numbers — and even bigger tensions.

In this episode, Wayne and Sally dive deep into one of our most culturally embedded and vital global systems. From soil health and water usage to biodiversity and the power of food to bring people together, the food system connects deeply to human health, culture, and planetary boundaries. But with food accounting for a third of global greenhouse gas emissions and millions facing acute hunger or unaffordable healthy diets, the need for a transition toward regenerative agriculture and systemic change has never been more urgent.

Is regenerative agriculture the ultimate solution? How can we empower farmers at the center of this shift? And what does it take to transform a system from the inside out? Wayne and Sally explore these questions alongside three key leaders transforming the food landscape.

Guests

• Andy Cato — Co-founder of Wild Farmed; award-winning farmer and Grammy-nominated musician.
• Brian Griffith — Executive Chairman of Griffith Foods; fourth-generation leader of a global B2B product development and food ingredient business operating across 30+ countries.
• Chantelle Nicholson — Award-winning chef, restaurateur, author, and owner of Apricity in London; independent board member for ReLondon and member of City Harvest's Food Council.

What We Cover

• Why the food system accounts for a third of global carbon emissions — and why $2.6 billion people still cannot afford a healthy diet.
• How regenerative agriculture shifts the focus from chemistry back to biology, restoring soil fertility and water infiltration.
• Why we must move past the false binary choice between food production and nature restoration.
• The financial realities facing farmers and the need to align economic incentives through private finance and community support.
• How B2B food businesses can embed purpose (People, Planet, Performance) across global supply chains.
• The critical role of culture, taste, and hospitality in changing consumer behaviour without lecturing.
• Why applied technology in food systems — like precision fermentation or upcycling waste — must serve biology rather than replicate fragile chemical models.

This Episode's Dance

Like a Tango, the food system involves equal and opposing forces — between business, government, farmers, and consumers. Navigating the transition requires a delicate, coordinated dance between culture, economics, policy, and nature to choreograph real systemic change.
