2017, equivalent to a reduction in cement per capita from 0.5 to 0.3 tonnes per person (3). The CO 2 intensity of cement production over that period has improved by about 7% (0.6t of CO 2 emitted per tonne of cement in 2017) (2). By 2050, cement production in the EU is expected to remain below pre-2010 levels, ranging between 165Mt
