Abiotic depletion
Definition
Abiotic depletion is an impact category concerned with the use or depletion of non-living natural resources such as minerals, metals or fossil resources.

This reference provides supporting context for how “Abiotic depletion” is defined and used.
Overview
What it means in practice
Abiotic depletion should be read as a life-cycle and product-footprinting term. Its meaning depends on the study goal, scope, data source, method and interpretation context.
In practice, users should state the boundary, baseline, data source and method. That keeps abiotic depletion useful as a reference without overstating the result.
Why it matters
Abiotic depletion matters because footprinting language determines what is counted, compared and communicated. Clear definitions make assumptions visible and reduce the risk of misleading comparisons.
Common misconception
A common error is to treat Abiotic depletion as a neutral technical label. The stronger approach is to explain the modelling choice and how it changes the result.
Review questions
What boundary, baseline or comparison is being used? What evidence supports the term? What assumption or limitation would change how a reader interprets it?
How it is used
In professional practice, “Abiotic depletion” helps designers, manufacturers, procurement teams, life-cycle practitioners and waste managers describe or assess an impact category concerned with the use or depletion of non-living natural resources such as minerals, metals or fossil resources.
It is commonly encountered in product design, procurement, footprinting, material selection, production and end-of-life decisions. A credible application identifies the product system, life-cycle stages, functional unit, geography, timeframe and measurement method.
