Abiotic resource depletion in LCA-background and update of the anthropogenic stock extended abiotic depletion potential (AADP) model

摘要

The depletion of abiotic resources needs to be discussed in the light of available geologic stocks. For the evaluation of long-term resource availability under consideration of the resources' functional relevance, the abiotic resource stock that is ultimately available for human purposes needs to be identified. This paper discusses the determination of geologic resources stocks and outlines an approach for the estimation of the resource stocks ultimately available for human use in the long-term. Based on these numbers, existing characterization factors for the assessment of resource depletion by means of the anthropogenic stock extended abiotic depletion potential (AADP) model can be updated.
