NeedsandLimits | ENL's Core Principles

1. Value is the objective effect of consumption on human beings, and is measured by physical health.
2. Cost is the objective effect of production on human beings. Because cost is the converse of value, it is also measured by physical health.
3. The optimum quantity for an output is reached when the marginal cost of its production equals the marginal value from its consumption.
4. An economy’s environmental budgets are set by the maximum rates of habitat destruction, waste generation, and renewables utilization that do not result in environmental degradation.
5. An output’s share of an environmental budget, called its budget share, is established by its relative contribution to health.
6. An output’s ecological limit is reached when the output has exhausted its lowest budget share.
7. An output’s target quantity is the lower of its optimum quantity and ecological limit.
8. An output may be produced beyond its target quantity in order to satisfy socially-sanctioned wants if its ecological limit is not violated.
9. The target rate for a natural flow is the minimum rate required by target output quantities at maximum ecological efficiencies.
10. A population’s optimum level is reached when average health is maximized due to scale effects.
11. A population’s target level is the lower of its optimum level and the area's carrying capacity.
