Guide on ISO/TS 19870: Promoting the Global Standard for GHG Assessment in the Hydrogen Value Chain
Author(s): UNIDO, ISO
ISO/TS 19870 is a comprehensive methodology for determining greenhouse gas emissions across the hydrogen value chain, from raw material extraction to the consumption gate. Developed through broad international consensus, it is designed to harmonize and streamline the partial carbon footprint calculation (the GHG emissions of specific segments of the supply chain) for various technology pathways in the hydrogen value chain.
UNIDO and ISO have developed the Guide to ISO/TS 19870 to make this standard more accessible to practitioners, industry professionals, and government stakeholders. The guide refers to ISO's Life Cycle Assessment (LCA) and Carbon Footprint of a Product (CFP) phases and the original ISO/TS 19870 sections, while providing relevant context and explanations. Through this approach, the guide supports ISO/TS 19870, addresses common questions, and enhances its visibility and recognition.
By promoting the use of ISO/TS 19870, the guide strengthens ISO/TS 19870 position as the international benchmark for GHG assessment in the hydrogen value chain, encourages adoption by a broader range of stakeholders, and fosters its implementation in diverse economies—ultimately contributing to a more unified global hydrogen market.
