kestävyyydeltään

kestävyyydeltään is a Finnish compound adjective that reflects the quality or degree of sustainability/ durability of an object, process or system. It is formed from the noun kestävyyttä (sustainability/durability) with the suffix -ltä (from) and the adjectival ending -en, indicating comparison or possession, so that the word literally means “with respect to its durability.”

The term is common in Finnish technical, environmental and business discourse. For instance, a product’s environmental footprint may be evaluated "kestävyyydeltään" to compare its ability to perform over time without excessive resource consumption. In engineering reports one might say “Tämän laitteen energiatehokkuus kestävyyydeltään on merkittävästi parempi” meaning “this device’s energy efficiency, from a durability standpoint, is significantly better.” The phrase is also used metaphorically in economics, for example, to describe a company's financial resilience: “Yrityksen velkakaava kestävyyydeltään on vahva.”

The formation follows a regular Finnish lexical pattern where a noun is followed by -ltä (from) plus the adjectival suffix -en, similar to words such as koulutettavuudeltaan (“with respect to trainability”). This construction signals a comparison against a reference value or standard.

kestävyyydeltään is not an everyday spoken word but appears frequently in written Finnish, especially in reports, research papers, and policy documents where comparative analysis of sustainability metrics is required. It is considered neutral and descriptive, fitting well into the objective style of official Finnish prose.
