Due to its versatility, durability, and affordability, concrete has become the world’s most popular building material. Since it is used on such an immense scale, it generates roughly 8% of global CO2 emissions. These emissions derived from production are referred to as embodied carbon.
However, the world will continue to need concrete to address 21st-century challenges like climate change, housing crises, and sustainable development. This means that industry, government, and academia must collaborate to reduce its environmental impact. The CSHub is evaluating the potential impacts of a variety of pathways to lower the embodied carbon of cement and concrete, including the possibility of achieving carbon-neutral—or even carbon-negative—concrete.
