Q&A: Why cement emissions matter for climate change
The production of Portland clinker, which acts as the binder, is a crucial step in making Portland cement. Limestone (CaCO3) is "calcinated" at high temperatures in a cement kiln to produce lime (CaO), leading to the release of waste CO2. Overall, the following reaction occurs: Why does cement emit so much CO2?
