If the steel industry were a country, it would be the world's third-largest emitter. So to prevent a climate catastrophe, this industry has to change. And not just a little bit: we have to fundamentally transform how we make one of the most versatile, durable, widely used materials human beings have ever created. That's exactly what a group of companies in northern Sweden is aiming to do.

This is Threshold Season 4: “Time to 1.5” In this episode we travel to northern Sweden to explore how a greener process could revolutionize the iron and steel industry, dramatically reduce fossil fuel emissions, and make life better for people in industrial communities.

This work depends on people who believe in it and choose to support it. People like you. Join our community at thresholdpodcast.org
