As of 2023, practically 2 billion metric tons of metal have been being produced yearly, sufficient to cowl Manhattan in a layer greater than 13 toes thick.
Making this metallic 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 excess of such sources as aviation.
A handful of teams and corporations are actually making critical progress towards low- or zero-emission metal. Amongst them, the Swedish firm Stegra stands out. The startup is at the moment 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 one in every of our 10 Breakthrough Applied sciences for 2025, MIT Know-how Assessment’s annual checklist of tech to observe. Try the remainder of the checklist, and solid your vote for the honorary eleventh breakthrough.
2025 is a vital 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 checklist of 10 Breakthrough Applied sciences.
As I used to be wanting over the completed checklist 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 obtainable or simply about to be. It’s actually apt, as a result of this yr specifically appears to be bringing a brand new urgency to the struggle 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.
