Host Jeni Miles talks to Anastasia Linn, co-founder of the Arketa Institute for Post-Growth Finance, about why sustainable finance is built on flawed economic foundations.
They explore ecological economics, the risks facing pension funds, moral purity in climate action, and why staying inside extractive industries — not leaving them — may offer the greatest leverage for change.
KEY TAKEAWAYS:
- Discover why neoclassical economics, the foundation of all mainstream finance, leaves nature and energy out of its models entirely.
- Understand the shift from an "empty world" to a "full world" economy, and why growth-based finance no longer fits planetary limits.
- Learn why walking away from extractive industries may be less effective than staying and using your position for change.
- Explore how "multi-capital" thinking (natural, social, human and manufactured capital) reframes what a secure retirement actually looks like.
- Hear why UK actuaries are warning that ecological collapse threatens the entire financial system, even as other institutions downplay the risk.
- Move beyond the trap of moral purity, and understand why shame-based climate narratives can hold back real systemic change.
- Find out why hope, in Anastasia's view, isn't something you wait for. It's something you build through action.
