The Problem with Cement Production

Cement production, particularly the use of Portland cement, emits large amounts of carbon into the atmosphere. For every ton of cement manufactured, nearly a ton of CO2 is emitted, making the cement industry the second largest industrial emitter of greenhouse gases. Cement and concrete are widely used in construction, and the demand for these materials is expected to increase as developing countries build more infrastructure. However, the carbon-intensive nature of cement production poses a challenge for mitigating climate change.
