Achieving Net Zero in the Cement Industry

Abstract

Cement production accounts for roughly 8% of global CO₂ emissions, making it a critical target for decarbonization. This research explores how a combination of carbon capture technologies, novel clinker substitutes, and digital optimization can cut cement-related emissions by up to 80% by 2050. Through case studies in China, Europe, and North America, I examine the techno-economic factors enabling full-scale carbon capture, as well as policy drivers. Analyzing economic impacts, the study reveals that sustainable finance can bridge capital gaps while mitigating first-mover risks. Results show that scaling these solutions requires robust regulatory support, extensive R&D, and new construction codes favoring low-carbon concrete. Lastly, the research highlights key barriers—including material scarcity, high abatement costs, and fragmented standards—and proposes collaborative pathways for governments, industry, and investors to accelerate a net-zero cement future. By integrating multi-stakeholder initiatives and leveraging emerging markets for “green cement,” this study provides a roadmap to transform one of the world’s largest industrial emitters into a climate-neutral sector.
