This study employed ozone as a clean oxidant for lignin depolymerization under mild, catalyst\u2010 and base\u2010free conditions. Grass lignin, rich in\n                    <jats:italic>p<\/jats:italic>\n                    \u2010coumaric acid (\n                    <jats:italic>p<\/jats:italic>\n                    CA), ferulic acid (FA) moieties, and \u03b2\u2010O\u20104 linkages, achieved 91.55% conversion with a 15.41% monomer yield and 18.43% carbon efficiency within 3\u2009min at 0\u2009\u00b0C, outperforming most reported systems in rate and selectivity. Process optimization and Van Krevelen diagram confirmed that ethanol served a dual role as a green solvent and reactant, enhancing sustainability compared to fossil\u2010derived solvents. Kinetic studies revealed that\n                    <jats:italic>p<\/jats:italic>\n                    \u2010hydroxyphenyl (H)\u2010type monomers exhibit higher stability than guaiacyl (G) and syringyl (S)\u2010type products. Softwood lignin with abundant G units and C\u2500C linkages gave a low monomer yield (2.40%), but high vanillin selectivity (&gt;90%). Hardwood lignin predominantly generated S\u2010type products, including syringaldehyde (selectivity 53.17%). Pearson correlation analysis linked lignin structural features, including unit composition, linkage types, and molecular weight to monomer yields and selectivity. Overall, this study highlights ozone oxidation as a promising route for rapid lignin valorization and demonstrates strong associations between lignin structural features and depolymerization efficiency and product selectivity.\n
