Proposal to establish a new Mutual Resolution No. 5 (M.R.5) concerning Automotive Life Cycle Assessment (A-LCA) to provide an internationally harmonised methodology for determining carbon footprint of light-duty vehicles across all life cycle stages—material production, parts production and vehicle assembly, use, and end-of-life—using a level concept that distinguishes four levels of detail based on data availability and study purpose, applicable to different powertrain types and energy pathways, with provisions for energy modelling, recycling methodology, discrepancy and deterioration factors, maintenance assessment, and third-party verification requirements for Levels 3 and 4.
