Heavy industry is still running on an outsized footprint, using 40% of global industrial energy while driving CO2 emissions at 12 Gt, about 30% of the world total in 2022. At the same time, the sector employs huge workforces and records major investment, with heavy industry revenue topping $4.5 trillion in 2022 and global mining employment reaching 40 million. This post puts those pressures and scale points side by side, from steel and cement to mining water and emissions, to show where the real bottlenecks and opportunities sit.
