Coal price rises will impact cement costs 28 January 2017 Although there has been a big move away from fossil fuels in many parts of the world, the cement sector still relies on coal as cheap fuel to fire a good number of its cement kilns.
Cement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production. Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately 3.4% of global CO 2 emissions from fossil fuel combustion and cement production.
