Can we secure the required massive supply of steel and how consequential is the metal’s global production? Do we have adequate supplies of iron ore to keep making steel for many generations to come? Can we produce enough of it in order to build modern infrastructures and raise the standards of living in low-income countries, where average per capita steel consumption is even lower than it was in the affluent economies a century ago? Is steelmaking environmentally friendly or is it exceptionally damaging? Can we produce the metal without using any fossil fuels?
