I reviewed the Doughnut Economics Action Lab 'About Doughnut Economics' page and included it in Chapter 'Call to Action: Our World & Our Future' (Part 1: The Purposeful Investor) because it explains the Doughnut framework — a compass that balances a social foundation and planetary boundaries — and summarises Kate Raworth’s 'seven ways' mindset and actionable Principles of Practice (including organisational design levers: purpose, networks, governance, ownership, finance). This directly supports the book’s argument to shift goals from GDP growth to thriving within ecological limits and provides practical design and investment-relevant guidance for purposeful investors seeking regenerative, distributive strategies (footnote: Page 23).
