Herman Daly - Toward some Operational Principles of Sustainable Development’

Three important operating rules that a long-term steady-state economy must incorporate –

1.      Exploit renewable resources no faster than they can be regenerated.

2.      Deplete non-renewable resources no faster than the rate at which renewable substitutes can be developed.

3.      Emit wastes no faster than they can be safely assimilated by ecosystems.

Taken from ‘Toward some Operational Principles of Sustainable Development’ by Herman Daly in Ecological Economics 2 no.1 (1990).
