Sustainability

Sustainability concerns meeting present needs while preserving the conditions for future needs, including ecological and social foundations. It requires explicit boundaries, distribution, and time horizons rather than indefinite repetition of every practice.

Sustainability asks whether meeting present needs preserves the ecological and social conditions on which future needs depend. The Brundtland formulation connects development with intergenerational responsibility, rather than requiring every activity to continue unchanged forever. System boundaries, distribution, replenishment, and the time horizon all affect the assessment.

In a practical application, distinguish a renewable flow from a stock being drawn down, and identify burdens shifted outside the visible system. A temporary drawdown may be deliberate and manageable if its purpose, limits, and recovery are credible. A claim of sustainability needs assumptions and indicators, not merely a reassuring label. A stable local result can still depend on costs borne by suppliers, communities, or future users.

When to use it

When present performance may deplete the resources or relationships needed for future functioning.

How it can help

Examine stocks, replenishment, dependencies, and burdens shifted to others or the future. Distinguish a bounded drawdown from an unsupported claim of continuing capacity.
