Carbon dioxide emissions from the world's steel sector will fall 30% by 2050 compared with last year as more mills turns to less-polluting electric arc furnaces (EAF), consultancy Wood Mackenzie (WoodMac) said in a study on Tuesday. Around 48% of global crude steel will be made via EAF by 2050, according to WoodMac, increasing from 30% in 2021 and almost on a par with traditional blast furnace steelmaking.
