What does it take to scale real-world climate solutions fast?

In this episode, we explore what happens when you treat climate action like an engineering challenge, not just a moral imperative.

Joining us is Nick Wirth, aerodynamicist, engineer, and former Formula One team owner turned cleantech entrepreneur. Today, he’s applying high-performance engineering to supermarkets, trucks, and buildings through Wirth Research, saving clients energy costs and cutting emissions with every installation.

Nick walks us through his journey from designing wind-tunnel-free F1 cars to developing AirDoor and EcoBlade, technologies which are now being used across the UK retail sector to cut heating and cooling loads by up to 70%.

We explore why sustainability only scales when it delivers a strong return, how overlooked retrofits could unlock widespread adoption of heat pumps, and what supermarkets reveal about behavioural economics and invisible design.

The good news is that the business case is stronger than ever. The challenge now is moving fast enough, and thinking big enough, to match the moment.

Nick’s story is a powerful reminder that many of the answers we need already exist. What’s missing isn’t innovation but implementation at scale. Listen in, and find out what it looks like when a Formula One mindset meets a broken energy system – and decides to rebuild it.

Let’s step out of the ESG echo chamber and into a much bigger conversation: what are the real limits of our planet and how close are we to crossing them? Life on Earth has remained stable for the last 12,000 years, but that stability is starting to unravel.

It’s tempting to treat climate change, pollution, biodiversity loss, and land use as separate “issues,” each with their own strategy, timeline, and department. But that’s not how Earth works, and businesses that think that way are flying blind.

In this week’s episode, Felicia speaks with Dr. Katherine Richardson, Earth system scientist, professor of biological oceanography at the University of Copenhagen, and one of the architects of the Planetary Boundaries framework.

We explore why six of the nine planetary boundaries have already been breached and what that really means for our future. Katherine explains how Earth system science reframes sustainability, moving us beyond the idea of simply doing less harm toward a far more urgent goal: staying within the planet’s safe operating space.

We may be overdue for a social tipping point, and business leaders can help accelerate that shift. We ask what executives actually need to understand about science (hint: it’s not the chemistry), and examine how outdated metrics, short-term thinking, and misaligned incentives keep many companies stuck, while others are quietly forging a different path.

This episode is a wake-up call, but also a message of hope. Change is happening, albeit not fast enough. But as we’ve learned from smoking bans to seat belts, social tipping points often come quickly if enough of us help push.

From climate volatility to food insecurity and antibiotic resistance, the global food system is at a breaking point. Industrial agriculture contributes up to 25% of global emissions, drives biodiversity loss, and strains farmers with volatile prices and precarity.

It’s clear we need to change how food is made, not just how it's consumed: one bold solution is clean agriculture.

In this week’s episode, Felicia speaks with Jim Mellon, entrepreneur, investor, and executive chairman of Agronomics, a company backing cellular agriculture and precision fermentation to create meat, dairy, eggs, and oils, without animal cruelty, deforestation, or ultra-processed additives.

Agronomics is invested in companies such as Meatly, BlueNalu, Liberation Labs, and Clean Food Group, aiming to industrially replace high-impact ingredients such as palm oil, dairy proteins, and even bluefin tuna with bio-identical, lower-impact alternatives.

In this episode, we unpack what clean agriculture really means, and why it’s fundamentally different from plant-based food and from GM. We explore its potential to cut emissions, reduce antibiotic use, ease pressure on land, and stabilise food prices in an era of growing volatility.

Jim Mellon why new fermentation infrastructure is critical, what investors often misunderstand about this emerging sector, and how dogs might just be the unlikely bridge to a cleaner, more sustainable future for meat.

Whether you care about emissions, animal welfare, farmer livelihoods, or just the price of chocolate, this episode makes the case for why clean agriculture might just be the food system moonshot we need.
