Just like most other countries, the UK is plotting a course to a cleaner, greener economy. But there’s a sticky issue at the heart of this transition – steel. From building turbines to laying train tracks, the country will need more steel if it wants to be greener. Producing it can be a polluting and costly business, however.

But they also rely on vast amounts of electricity – which doesn’t come cheap in the UK. On top of that, a flourishing trade in selling scrap overseas means those prices are high, too.
