Impacts and dependencies
analysis
The sector-average assessment of the top drivers
of nature loss shown in Table 2 is mostly based on
ENCORE,308 and follows a four-step process.
First, the relevant sub-industries were identified
at an ISIC class level309 for each stage of the
value chain. After initially shortlisting the ISIC
classes for the midstream section of the value
chain (direct operations), the ENCORE upstream
and downstream “links” were used to map each
midstream ISIC class to relevant upstream and
downstream ones. A manual review was also
conducted to identify any other relevant categories,
resulting in a total of 68 ISIC classes mapped to the
value chain stages for the mining and metals sector.
Second, the ENCORE “pressures” were mapped
to the five IPBES (Intergovernmental Science-Policy
Platform on Biodiversity and Ecosystem Services)
drivers of biodiversity and ecosystem change.310
Note, “Resource exploitation” was mapped solely
to “Volume of water use”, as the other pressures
(“Other biotic resource extraction (e.g. fish, timber)”
and “Other abiotic resource extraction”) were not
material for the mining and metals sector, and
“Introduction of invasive species” was similarly
excluded given the materiality was mostly low
or below for all ISIC classes where a value was
assigned. See Table 8 for the complete mapping. Third, for each stage of the value chain and IPBES
driver, an average of the ENCORE “pressure
materiality rating” was computed across all the ISIC
classes where a materiality value was assigned (i.e.
not N/A or ND). This was summarized in Table 2 for
those with medium, high or very high materiality.
Finally, this output was tested with business,
civil society and academic industry experts via
interviews and consultation workshops, and
the final ratings were adapted based on the
feedback provided. For the mining and metals
sector specifically, this involved updating the
“midstream, land-use change and ecosystem
disturbance” from medium to high materiality,
and the “downstream, greenhouse gas emissions”
from low to medium materiality.
The impact and dependency descriptions in
Chapter 2 also use the ENCORE “pressure
materiality ratings”, “pressure links”, “dependency
materiality ratings” and “dependency links” datasets
alongside several other sources. These include
CDP Water Watch, WWF Water and Biodiversity
Risk Filters, academic papers, civil society reviews,
company-specific insights and assessments,
analysis by the World Economic Forum and industry
expert interviews and consultation workshops. The
results of this analysis were then used to inform the
development of the priority actions.
