Cement Energy Environment

43 Innovative and emerging technology Key Indicators for the Brazilian Cement Industry by 2050 The viability of innovative and emerging technology would reduce around 38 Mt of CO 2 or 9% of cumulative mitigation of CO 2 emissions by 2050 in the “2˚C Scenario”, in comparison with the “6˚C Scenario”. Key message: Carbon capture, an alternative still emerging for the mitigation of CO 2 , emissions, would become viable for the Brazilian cement industry only after 2040.

Alternative fuel use includes biomass as well as renewable and non-renewable waste. Electricity intensity of cement production does not include reduction in the demand for purchased electricity from waste heat recovery equipment or electricity used in carbon capture equipment. Direct CO 2 intensity refers to net CO 2 emissions, after carbon capture.
