The blended cement has been produced at the site for over 15 years. However, Cemex says it is growing production to meet the company’s carbon reduction goals and meet increased demand for lower carbon materials.

US: The California Department of Transportation (CalTrans) has approved the use of Portland limestone cement (PLC) in its projects. The California Nevada Cement Association (CNCA) says that the move has the potential to eliminate 25,500t/yr of CO₂ emissions.

The CNCA plans to achieve cement and concrete carbon neutrality by 2045 through three priority actions. These are investment in promising and critical long-term technologies (crucially carbon capture, utilisation and storage (CCUS) technologies), increased alternative fuel (AF) substitution and the acceptance of PLC for CalTrans projects. Thus, the latest CalTrans decision marks the establishment of one pillar of the CNCA’s ambitious plan for net zero.
