As of 2023, practically 2 billion metric tons of metal had been being produced yearly, sufficient to cowl Manhattan in a layer greater than 13 toes thick.
Making this steel produces an enormous quantity of carbon dioxide. General, steelmaking accounts for round 8% of the world’s carbon emissions—one of many largest industrial emitters and way over such sources as aviation.
A handful of teams and firms at the moment are making severe progress towards low- or zero-emission metal. Amongst them, the Swedish firm Stegra stands out. The startup is presently constructing the primary industrial-scale plant on the earth to make inexperienced metal. However can it ship on its guarantees? Learn the total story.

Inexperienced metal is certainly one of our 10 Breakthrough Applied sciences for 2025, MIT Know-how Evaluation’s annual listing of tech to observe. Try the remainder of the listing, and forged your vote for the honorary eleventh breakthrough.
2025 is a important yr for local weather tech
—Casey Crownhart
I like the contemporary begin that comes with a brand new yr. And one factor including a lift to my January is our latest listing of 10 Breakthrough Applied sciences.
As I used to be trying over the completed listing this week, I used to be struck by one thing: Whereas there are some entries from different fields which might be three and even 5 years away, all of the local weather objects are both newly commercially accessible or simply about to be. It’s actually apt, as a result of this yr particularly appears to be bringing a brand new urgency to the combat in opposition to local weather change. It’s time for these applied sciences to develop up and get on the market. Learn the total story.
