Fig. 4: GHG emissions pathways of the aluminium industry.
From: Different technology packages for aluminium smelters worldwide to deliver the 1.5 °C target
a–g, Total GHG emissions from the primary aluminium smelting sector in global (a), Europe (b), North America (c), China (d), India (e), Middle East (f) and Africa (g). The light shaded area represents the range of highest and lowest emissions pathways under the five SSP–RCP scenarios. The bold lines depict the five technology narrative pathways. The bar chart represents the emissions structure under P5, illustrating the most climate-ambitious scenario for the global aluminium industry, which adopts all possible technological strategies to mitigate GHG emissions.
