I'm a believer that we should first focus on redesigning the specific systems in our lives where we can see tangible change, then let a label come later. Certainly don't think Doughnutism will be the name of future economics, but I'm a big fan of Kate Raworth's Doughtnut Economics theory that advocates for ~~"humanity striking a balance between the maximum capacity of our environment and the minimum basic quality of life that every person has a right to." It's about balancing our production & consumption with the environmental limitations of Earth, based on very specific metrics from UN climate scientists which makes it easier for us to track our progress.
Would highly recommend watching her TED talk for an optimistic vision for the future of economics! I wrote about the theory & also about the City of Amsterdam applying Doughnut Economics as their official economic policy during the COVID pandemic, requiring companies to develop a circular supply chain among other things:
