156 Marcus Feldthus: the Post-Growth Guide

Artwork for Circular Economy Podcast episode 156

We zoom out to the economy part of the circular economy to talk about the Post Growth concept with Marcus Feldthus.

Together with Oscar Haumann, Marcus founded the Post Growth Guide back in 2023, as a learning space for people who want to understand the social and planetary boundaries so as to make real sustainability strategies, avoiding greenwashing, going beyond compliance, and leading the way forward for their business and wider industry.

The platform has a growing membership community and offers explainers, case studies, online courses, books, and public talks.

Marcus Feldthus is an entrepreneur from Denmark with a Master’s Degree in Business from Copenhagen Business School. Marcus, with Oscar Haumann also started a consultancy called Abel, back in 2015.

Marcus will explain the concept of Post Growth, its historical roots and what its aiming to achieve, and we talk about how the circular economy fits into a Post Growth system. We discuss how Post Growth is gaining traction and how it aligns with some of the other approaches to progressive economic, including degrowth and regenerative economics.

Marcus tells us more about the Post Growth Guide and course, about his new book, “The Economies of Small Scale”, coming out soon, and why conversation starters are a great tool to help us all think about this from practical, business perspectives.

International speaker, author and strategic advisor, Catherine Weetman helps people discover why circular, regenerative and fair solutions are better for people, planet – and prosperity.

Catherine’s award-winning book: A Circular Economy Handbook: How to Build a More Resilient, Competitive and Sustainable Business includes lots of practical examples and tips on getting started.
