Climate Entrepreneur Mini Documentaries
Zeroing in on Climate Solutions that Work
At the Climate Knowledge Initiative (CKI), our job is to zero in on climate solutions that work and to steer attention toward investable and scalable technologies. That often means looking at hard-to-abate sectors like cement, steel, and construction.
We teamed up with The YEARS Project to showcase how some of the most promising climate entrepreneurs are disrupting legacy industries and building a low-carbon future.
Sublime: Cleaning up cement, one electron at a time
In a small warehouse just across from a local brewery, Leah Ellis and her team of young, ambitious scientists are working on something incredible. They’re making a new kind of cement to solve one of the industry's biggest problems: pollution. Cement production is a massive contributor to climate change. Climate Economist and @ColumbiaBusiness Professor Gernot Wagner heads to Sublime System’s laboratory to see what’s really going on.
Stegra: Steel is one of the world’s dirtiest industries, but a company in Sweden may have an answer
Deep in Northern Sweden, just outside the Arctic Circle, a high-tech steel company is working on something new. It’s called Green Steel and it could change our world. @ColumbiaBusiness Professor and Climate Economist Gernot Wagner heads to Sweden to find out if this company really cracked the code to clean steel.
Brimstone: How one company uses different rocks to make the same cement
Cement production is something we rarely think about, but it’s one of the largest contributors to climate change. As more cement is needed every year, is there anything we can do to stop this problem from building up? Caltech Ph.D. Cody Finke has a high-tech solution and he’s already attracting big name investors. @ColumbiaBusiness Professor and Climate Economist Gernot Wagner heads to Brimstone's laboratory to see what’s really going on.
