China National Building Materials

China National Building Materials is the world's largest cement producer, manufacturing approximately 500 million metric tons of cement annually. The cement sector is responsible for roughly 8% of global CO2 emissions, and CNBM's production scale makes it a significant contributor to this total. The company's decarbonization strategy relies heavily on carbon capture, utilization, and storage (CCUS) technologies, which are not yet commercially viable at the scale required. Its published climate targets lack a clear, near-term roadmap for reducing process emissions from clinker production, which are intrinsic to cement chemistry and constitute the majority of the sector's carbon footprint. This technological reliance and absence of a detailed transition plan for its core industrial process represent a form of climate intransigence, as they defer material action on its largest emission source.
