Find the Safe and Just Doughnut Space

Doughnut economics seeks a space where social foundations are met without crossing an ecological ceiling.

Below the inner ring means unmet needs; beyond the outer ring means overshoot. Regenerative design restores systems, while distributive design shares value and opportunity.

A housing plan can move inward by improving access while moving outward if its energy demand exceeds ecological limits; judge both rings together.

No. The goal is meeting needs within ecological limits, not maximizing activity inside the ring.

The doughnut is not a growth target; it is a safe-and-just space test.
