kestävämmin

Kestävämmin is a Finnish adverb meaning “more sustainably” or “more durably,” depending on context. It is the comparative form of the adjective kestävä, which expresses sustainability or durability. The word is formed by adding the comparative adverb suffix -mmin to the stem of the adjective, allowing it to describe the manner in which an action is carried out or the quality of a process, product, or system as being more sustainable or more durable than a reference point.

In usage, kestävämmin typically appears in statements about improvements or comparisons. It can modify verbs to indicate that something is done with greater sustainability, for example: “Rakennushankkeita suunnitellaan kestävämmin” (Construction projects are planned more sustainably). It can also describe processes or practices, such as: “Energiankäyttöä vähennetään kestävämmin kuin ennen” (Energy use is reduced more sustainably than before) or “Laite on kestävämmin rakennettu” (The device is built more durably).

Relation to other terms: kestävämmin is closely related to kestävä (sustainable, durable) and kestävyy (sustainability). While kestävämmin expresses relative improvement, the adverb kestävällä tavalla or kestävällä tavalla phrasing can be used to emphasize a general, non-comparative manner, and kestävällisesti is a more common adverb for “sustainably.” The term is widely used in environmental, corporate, and policy discourse to articulate ongoing efforts toward greater sustainability or durability.
