This chapter discusses the importance of addressing standardization issues, considering its strategic role, and then discusses it in the context of Carbon Capture and Utilization (CCUS) technologies. Standardized metrics, guidelines, and protocols facilitate transparency, comparability, and regulatory compliance, essential for scaling up CCUS projects and integrating them into broader climate strategies. The inconsistent use of abbreviations and terminology introduces technical complexity, impairing communication, public perception, and policy formulation. Establishing standards for technical terms, performance metrics, and operational guidelines is strategic for organizing processes and enhancing stakeholder understanding. CCUS presents unique standardization challenges, and international cooperation through standardization forums, like ISO/TC 265 and CEN/TC 474, contribute to developing and harmonizing CCUS standards. Focusing on a comprehensive approach to standardization, the CCUS industry can overcome current barriers and accelerate its deployment to achieve climate goals.
