Regional Doughnuts
One framework. Many places.
One of the Doughnut's greatest strengths is its scalability. It can be applied at the global level or tailored to the unique context of a state, region, county, or city.
CalDEC is working with cities and counties across California to assess where they currently sit within the Doughnut and to identify priority areas for action.
