Switzerland: LafargeHolcim reduced its net CO2 emissions per tonne of cementitious material by 1% year-on-year to 576kg CO2/t in 2018 from 582kg CO2/t in 2017. It said that the improvement was achieved by reducing the clinker-to-cement ratio and consuming less energy per tonne of cement, mostly by using alternative fuels and improving the efficiency of the company’s processes. However, data from its Sustainability Report 2018 shows that both its overall gross and net emissions grew. Its net CO2 emissions from cementitious material increased by 2.5% to 121Mt. At the same time its clinker production rose by 2.7% to 151Mt from 147Mt.
The group increased its treatment of waste-derived resources to 52Mt. its alternative raw material substitute rate grew to 11.2% from 10.7%. It established a new pre-processing facility in Madukkarai in India and upgraded its waste handling capacities in Mexico, Ecuador, Brazil, Argentina, the Czech Republic, Bulgaria, India, Canada, Spain and Germany. It also reduced its freshwater withdrawal for cement production and improved its lost time injury rates.
