Q&A: Why cement emissions matter for climate change ,
Why does cement emit so much CO2? Around half of the emissions from cement are process emissions arising from the reaction above This is a principle reason cement emissions are often considered difficult to cut: since this CO2 is released by a chemical reaction, it can not be eliminated by changing fuel or increasing efficiency
