Concrete is one of the most important substances in the world. As the linchpin of the built environment, demand has almost tripled during the past 20 years. In 2021, global construction projects consumed 30 billion tonnes of the stuff. That’s 3 million times the weight of the Eiffel Tower.
But concrete has an emissions problem.
Today, its production is responsible for 8% of the world’s greenhouse gas emissions. With every tonne of cement made, almost a tonne of CO2 is emitted.
This time, I get the chance to sit with Grant Quasha, a man with a plan to solve this problem. He is the CEO of Eco Material Technologies, a company taking the built environment by storm by decarbonising concrete wit its concrete substitutes. And he’s selling millions of tonnes of the stuff across North America.
