An ecological balance sheet applies the two-sided logic of accounting to what a project does to the whole field, not just to its budget. On one side, the assets it creates: new skills, infrastructure, knowledge, networks, optionality, institutional capability. On the other, the liabilities it creates: resource depletion, dependency, concentrated power, environmental damage, deskilling, exclusion, fragility, lost alternatives. The difference is its net ecological position once the work is done.
Why it changes decisions
Two projects can look nearly identical on a financial statement and completely different on an ecological one — same cost, same output, but one leaves trained people, local suppliers, and open knowledge while the other leaves a proprietary dependency and an external workforce. The balance sheet makes that difference visible, and it is what makes it possible to choose projects by capacity return rather than price alone. See Choosing Projects by Ecological Return.
