Correcting remaining truncations in hybrid life cycle assessment database compilation

Hybrid life cycle assessment (HLCA) strives to combine process-based (PLCA) and environmentally extended input–output (EEIO) analysis bridge gaps of both methodologies. The recent development HLCA databases constitutes a major step forward in achieving complete system coverage. Nevertheless, current applications still suffer from issues related incompleteness the inventory data gaps: (1) hybridization without endogenizing capital inputs EEIO database leads underestimations, (2) unreliability price hinders application streamlined for processes some sectors, (3) sparse coverage pollutants multiregional limits handful impact categories. This paper aims at offering methodology tackling these manner visualizing their effects on scores across an entire PLCA multiple Data reconciliation algorithms are demonstrated ecoinvent3.5 EXIOBASE3.
