Fig. 4

a Supply ratio of secondary materials and annual net material demand after secondary materials supply under early-loss scenario in SDS for different materials. In each panel, the line chart (left axis) represents the supply ratio (same scale across all materials except Ag and Te), while the bar chart (right axis) represents net material demand (with varying scales). b Supply ratio of secondary materials and annual net material demand under the early-loss scenario for total materials in the SPS and NES. c Supply ratios and net material demand under the regular-loss scenario for total materials in the SPS, SDS, and NES. The three energy scenarios are defined as follows: SPS stated policies scenario, SDS sustainable development scenario, NES Net-Zero Emissions Scenario. Mt denotes megatonne, and Kt denotes kiloton.
