There are alternatives to highly polluting blast furnaces, but they require vast quantities of green electricity
Wind turbines and washing machines, skyscrapers and ships — they all have one thing in common: steel. Strong, durable and recyclable, this alloy of iron and carbon is one of the world’s most common manufacturing materials. But the steel industry is also one of the most polluting, accounting for 7-9 per cent of global carbon dioxide emissions, according to the World Steel Association.
5C above pre-industrial levels, as per the Paris Agreement. The International Energy Agency’s Net Zero by 2050 scenario calls for more than half of steelmaking capacity to use EAF by 2050. But, on current plans, only 32 per cent of total capacity will be using EAFs by then, according to Global Energy Monitor. Much will depend on China.

But an experience like stand-up teaches you about a quality vital to success: resilience.
