Figure 3. Within the materials sector, company impacts
vary across and within industries. Impacts are shown for three
ecosystem service metrics (coastal risk reduction, nitrogen retention,
sediment retention) and four biodiversity metrics (habitat for endemic
species, habitat for threatened and endangered species, total species
richness, and Key Biodiversity Areas). The values for each metric should
be interpreted as indices; values are comparable within a metric but not
between different metrics. For each boxplot, the midline indicates the
median, with boxes extending from the 25th to 75th percentiles and
whiskers extending to 1.5 times the interquartile range. Outliers beyond
1.5 times the interquartile range are indicated as dots. Note the log
scale of y-axes. The top row shows the total impact, which is affected
by the number, size, and location of each companies’ physical assets.
The middle row shows impact adjusted by company revenue. The bottom row
shows total impact adjusted by the total area (km2) of
physical assets. A higher impact per km2 indicates a company’s assets
are located in areas with great ecosystem service or biodiversity
values.
