Headline: Interpretation of LCA results. A worked example on a CO2 to fertilizer process

This worked example is part of a series of examples that are designed to provide practical guidance to the application of the Techno-Economic Assessment and Life Cycle Assessment Guidelines for CO2 Utilization. In this worked example the impact of “picking and mixing” inventory data on results interpretation is explored in detail. The results of 18 LCA inventories (for a CO2 to nitrogen rich fertilizer pathway) are assessed, showing the inconsistencies in the conclusions drawn from the interpretation phase of the studies.
