As of 2023, China’s transportation energy carbon emissions account for over 10%, which has a significant impact on achieving “dual carbon” goals. China successively issued various policies to address pollution in the industry. This study mainly analyzes synergistic effects reduction and measures implemented this We selected 2023 as base year, focused promoting new vehicles (NEVs), advocating bus transit (ABT), advancing rail (ART) three major emission policies, analyzed their air pollutant control greenhouse gas reduction. Based national scale data driving conditions, consumption, factors, reductions gases pollutants brought about by were first calculated. Then, using coordinate system effects, cross elasticity analysis pollutants, normalization evaluation methods, multi capabilities each policy quantified. Quantitative results revealed that NEV substitution achieved CO2 100.966 million tons alongside 1.0196 (CO), 59,506 (NOx), 103,500 (NMHC), 6266 (PM10), 3071 (SO2). APeq ranking, its comprehensive benefits (APeq = 166,734.52) significantly outperform ART 97,414.89) ABT 19,796.80). The main research conclusion shows replacing private gasoline cars with can have effect all five types involved study, positive effect. Moreover, development priority is relatively better based equivalent. Both buses not SO2 reduction, nor they had On basis, also contribute NOx emissions. For other both reducing
