Evaluating net-zero for the Indian cement industry: marginal abatement cost curves of carbon mitigation technologies

This report analyses carbon abatement measures for achieving net zero in the cement industry and plots a MAC curve for existing plants across the country. The marginal abatement cost (MAC) curve plots the annualised CO2 mitigation cost (USD/tCO2 ) of a given carbon mitigation technology against the total mitigation potential (tCO2) of that technology. The carbon abatement measures investigated can broadly be classified into four categories– Energy efficiency (EE), use of alternative fuels and raw material (AFR), use of renewable energy and alternative fuels such as biomass and municipal solid waste instead of fossil fuels, clinker factor reduction (CF) and carbon management solutions.
