As much as 60 pct of the emissions from the cement sector come from the production of clinker, the active component of cement. This primarily uses calcium carbonate as a source of calcium for the clinker, but releases a great deal of CO2. Outside of carbon capture technology, use of new efficient kilns could mean "a 10 pct improvement in the best case scenario at the global level [of emissions]", says the report. The report notes that the concrete-cement sector accounts for approximately 8 pct of global emissions.
The report concluded that total decarbonisation to keep the concrete-cement sectors in line with a 1.5 degree C Paris climate agreement target was "technologically feasible" but would "require very large investments."
