nachhaltig

nax.hal.tɪç

The adjective carries two clearly distinct meanings: the environmental and economic concept of sustainability, and an older sense of something deep or enduring. The right English equivalent depends entirely on which sense is intended.

1. sustainable · environmental, business, policy

Used wherever the focus is on ecological responsibility, resource conservation, or long-term economic viability.

Nachhaltiges Wirtschaften ist längst kein Nischenthema mehr.
Sustainable business practices are no longer a niche concern.
Die Stadt plant, ihren gesamten Nahverkehr nachhaltig zu gestalten.
The city plans to make its entire public transport system sustainable.

2. lasting · figurative

Describes a deep, enduring effect, most commonly paired with verbs like impress, shape, or shake.

Der Besuch in der Gedenkstätte hat ihn nachhaltig erschüttert.
The visit to the memorial left him with a lasting sense of shock.
Seine Theorien haben die Wirtschaftswissenschaften nachhaltig geprägt.

Notes

The environmental movement has narrowed the everyday meaning of nachhaltig to sustainable. However, in phrases like Das hat mich nachhaltig beeindruckt it means deeply or profoundly - translating it as sustainable there would be a clear error. This ambiguity is especially common in older texts and formal prose.
