Evaluating Net-zero for the Indian Cement Industry - Marginal Abatement Cost Curves of Carbon

from the cement Our baseline estimates show that nearly 56 per cent of the total 0.66 tonnes of CO2 per tonne industry of cement produced is due to the calcination of limestone in the kilns. [...] Thirty two per cent of emissions can be reduced without increasing the cost of cement The transition to net-zero cement will significantly increase the cost of the final commodity to the consumer. [...] Typically, the sum of all values of each bar on the y-axis indicates the total price per unit of emissions for achieving net-zero emissions, whereas the sum of all x-axis values indicates the total CO2 emissions (or mitigation potential) for the base year used to develop the curve. [...] Based on industry feedback, the operating costs for the equipment were assumed to be a percentage of the CAPEX or as a function of the net fuel or electricity (after accounting for the savings on account of the adoption of the energy efficiency or decarbonisation measure) used to operate the equipment. [...] The only competing product for the LC3 is the OPC since the targeted clinker factor is already the least for the PSC cement.
