UK scientists found a way to slash nearly 90% of carbon emissions from the country's steel industry

• UK scientists found a way to clean up blast furnaces, the most carbon-intensive part of steelmaking.
• Steel accounts for up to 9% of global emissions and is one of the most difficult climate challenges.
• UK scientists are searching for industrial partners to test their new method in a pilot plant.

Steel built much of our modern world, but it also racked up a massive carbon footprint along the way.
