Regarding the replacement of fossil fuels, the Cement Sustainability Initiative states that it can be a good option to reduce fossil fuels usage with lower atmospheric emissions if well controlled. The extraction of 100 kg of diesel oil can emit 62.7 kg of CO2 equivalents and contributes to fossil depletion with 127 kg of oil equivalent. However, due to the large use of road transportation in Brazil, the distances between the source of the alternative fuels and the plant must be taken into account.
