The report identifies clinker production as the primary source of emissions in the cement sector, accounting for 88% of total emissions. It evaluates three main decarbonization levers: substituting clinker with materials like fly ash and calcined clay, replacing coal and gas with biomass, waste, or green hydrogen, and deploying CCUS. While some progress is noted in developed markets, the report warns that absolute emissions will rise as production grows in emerging markets like India and Africa unless green processes are scaled. Key barriers include supply constraints for substitutes, high upfront costs for CCUS, and a lack of carbon transport infrastructure in high-growth regions.
