How we stop cement ruining the climate

Cement is the second most consumed commodity on Earth. That's a problem. Learn more about the climate crisis on Nebula (and get 40% off with my code): https://go.nebula.tv/simonclark

Our carbon emissions are overwhelmingly from our use and generation of energy, which means that our response to the climate crisis largely needs to be the decarbonisation of energy, specifically ending our dependence on fossil fuels. However, around one quarter of all our emissions come from other processes, one of the largest of which is construction. These emissions are mostly from cement production, due to the nature of making cement.
In this video I shine a light on one company - LEILAC - who are developing what I think is a realistic, scalable solution to this problem. Which, in what may be a surprise to some, involves carbon capture technology. I also ask how a company has made a business model out of preventing carbon emissions, and what this tells us about how capitalism can respond to the climate crisis.

Video about cement production, cement CO2 emissions, cement carbon emissions, how cement is ruining the climate. In this video I talk about unavoidable carbon emissions, and a fringe case that calls for the use of carbon capture technology, and look at a company providing carbon capture technology called LEILAC. If you like video essays about climate change from Wendover, Real Engineering, Smarter Every Day, It's OK to be Smart, or Veritasium, you'll enjoy this fun science video about carbon capture.
