Tree plots - ‘footprints’ - across 9 indicators for our palette of 18 elements. Each indicator is represented by a block for 18 elements. The size and color of each sub-block represent the indicator value for each element. Darker red hues and larger block sizes denote higher impacts. MP-material price, SR-supply risk, NVSR-normalized vulnerability to supply restriction, EE-embodied energy, WU-water usage, RMR-rock-to-metal ratio, HHD-human health damage, HRP-human rights pressure, LRP-labor rights pressure.
