Hydrogen is increasingly recognized as a pivotal component in the global drive towards decarbonizing energy systems. This collaborative UNIDO/ISO guide underscores the critical role of ISO/TS 19870 in establishing a harmonized and transparent framework for measuring and comparing emissions across diverse hydrogen production pathways.

Such standardization is fundamental to advancing international trade, shaping effective policy frameworks, and creating robust mechanisms for low-emission hydrogen, thereby supporting the transition to a sustainable energy future.
