The direct CO2 intensity ofcement productionincreased 0.5% per year during 2014-18. To get on track with the SDS, a 0.8% annual decline is necessary to 2030. Sharper focus is needed in two key areas: reducing the clinker-to-cementratio (including through greater uptake of blended cements) and deploying innovative technologies (including CCUS)

G. Habert, in Eco-efficient Construction and Building Materials, 2014 10.1 Introduction.Cement productionhas undergone tremendous developments since its beginnings some 2,000 years ago. While the use ofcementin concrete has a very long history (Malinowsky, 1991), the industrialproductionof cements started in the middle of the 19 th century, first with shaft kilns, which were later
