As of 2023, almost 2 billion metric tons of metal have been being produced yearly, sufficient to cowl Manhattan in a layer greater than 13 ft 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 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 complete story.

2025 is a essential 12 months for local weather tech
—Casey Crownhart
I like the contemporary begin that comes with a brand new 12 months. And one factor including a lift to my January is our latest record of 10 Breakthrough Applied sciences.
As I used to be trying over the completed record this week, I used to be struck by one thing: Whereas there are some entries from different fields which are three and even 5 years away, all of the local weather objects are both newly commercially out there or simply about to be. It’s definitely apt, as a result of this 12 months particularly appears to be bringing a brand new urgency to the struggle towards local weather change. It’s time for these applied sciences to develop up and get on the market. Learn the complete story.
