I totally understand your impulse here. The Doughnut is such a compelling model and I think many people are trying to figure out how best to apply the model at a more micro-economic level. I suggest that you check out the Strongly Sustainable Business Model Group - and if you use LinkedIn, there is a group with over 1500 members globally. Simply search for the group in LinkedIn and ask to join.
The group was created around the graduate work of Antony Upward, in Toronto. Anthony took Alex Osterwalder’s “Business Model Generator” book and considered how this framework could be adapted to fully embrace the challenges and opportunities for creating ‘sustainable’ businesses, and not simply ‘successful’ ones. I’ve been part of the group since 2013, about a year after group began to form. We continue to have monthly face-to-face meetings, which are all broadcast over the internet, as well as recorded and accessible for anyone. Each monthly meeting involves one or two presenters - from all over the world - working on this.
Although we have drawn inspiration from a history of inspired thinking in ecological economics, Kate’s book on “Doughnut Economics” has provided a major boost. It seems that the two levels - Kate’s macro-economic level, as well as business/enterprise-based micro-economic strategies, structures, feedback loops and systems - require bridging.
So, please have a look at the SSBMG materials (and you can find more info on websites if you check out http://ssbmg.com/ as well as www.flourishingbusiness.org. We are in the process of building a Flourishing Enterprise Institute, which is envisaged as being a decentralized research and development network around the world. There’s lots going on!
