Development of Specific Rules for the Application of Life Cycle Assessment to Carbon Capture and Storage

Carbon Capture and Storage (CCS) is a very innovative and promising solution for greenhouse gases (GHG) reduction,<i> i.e.</i>, capturing carbon dioxide (CO₂) at its source and storing it indefinitely to avoid its release to the atmosphere. This paper investigates a set of key issues in the development of specific rules for the application of Life Cycle Assessment (LCA) to CCS. The following LCA-based information are addressed in this work: definition of service type, definition of functional unit, definition of system boundaries, choice of allocation rules, choice of selected Life Cycle Inventory (LCI) results or other selected parameters for description of environmental performance. From a communication perspective, the specific rules defined in this study have been developed coherently with the requirements of a type III environment label scheme, the International EPD^® System, according to the ISO 14025 standard.
