Fig. 3: Diamond industry environmental impact projections under two SSPs scenarios.
From: The environmental impacts and sustainable pathways of the global diamond industry
a–f represent GHG emissions projections under the assumptions of the SSP1-1.9 (blue) and the SSP2-2.6 (red); g–l exhibit mineral waste disposed or stored projection under the SSP1-1.9 (green) and the SSP2-2.6 (orange); m–r show both potable and non-potable water usage projection of the SSP1-1.9 (purple) and the SSP2-2.6 (yellow). All projections are presented with shaded confidence intervals. Each data is presented as mean values ± standard error of the mean (SEM) based on 95% confidence intervals calculated by two-tailed t-tests (p < 0.05). The selected regions include Australia (a, g, m); Russia (b, h, n); Botswana (c, i, o); DR Congo (d, j, p); South Africa (e, k, q) and Others (f, l, r). The horizontal coordinates present years from 2030 to 2100 and the vertical coordinates for GHG emissions and mineral waste are millions of tones; vertical coordinates for water usage are millions of m3.
